ELECTROLUX WASHING MACHINES AND DISHWASHER ERROR CODES AND TROUBLESHOOTING RECOMMENDATIONS

ELECTROLUX WASHING MACHINE – ERROR CODES LIST – CAUSES – TROUBLESHOOTING LIST

 If you try to describe the machines of the Swedish brand Electrolux briefly, the first things that come to mind are their durability and endurance. But these units do not have an infinite operating life.
The fact that there is something wrong with the automatic device is evidenced by problems with spinning, the powder that is not washed out from the dispenser, extraneous noises and puddles on the floor, or an error code appears on the display suggesting the nature of the failure. First, review the instructions – you can fix some problems yourself.

What do the incomprehensible symbols on the display of the Electrolux automatic washing machine mean? Most often, these are indications of certain errors. Knowing the error codes of Electrolux washing machines, we will be able to quickly find the faulty unit or repair some or other failure. In addition, error codes of Electrolux washing machines will help cope with abnormal situations. If the manufacturer recommends referring to professionals, call for Electrolux specialist to repair the washing machine.

We put all the codes in a small table with which you can quickly carry out the diagnosis of your washing machine. But as practice shows, some errors are missing from this table. For example, EH0 error in the Electrolux washing machine indicates a low supply voltage, and such a code cannot be found in the tables for services.

Code	Causes
10:11 REAL TIME CLOCK OUT OF ORDER	The real time clock is used by the CPU, measuring time, power failure, error codes, etc. The error code is activated if there is a time out in the communication with the internal real time clock in the CPU or if the data sent to/from the real time clock is incorrect. The error can only be removed by turning of the power to the machine for 30 seconds.
10:13 INITIALIZATION FAILED	The CPU has an internal time limit for initialization of the system. The error code is activated if 15 seconds has expired during start up and the hardware still is not initialized. Press the control knob/start button to retry.
11:1 NO WATER	When filling with water, the level specified by the program must be attained within a certain time. This time is normally set to 10 minutes but can vary depending on the type of machine and the software. If the filling time exceeds the maximum allowed filling time, this error code will be displayed. Long filling times can be caused by a blocked filler valve, defective filler valve, a break in the cable between the filler valve control board, defective valve control board, leaking level system, etc.
11:2 DOOR OPEN	This error code can only arise during an on-going program. This error code will be displayed if the control system detect that the input for door closed has been deactivated during an on-going program. This can be caused by for example a bad or defective door lock, loose cable to door lock, problem with door lock edge connection.
11:3 DOOR LOCK FAIL	This error code can arise at program start. If the door lock doesn't lock within a certain time after program start, this error code will be displayed. This error code will also be displayed if the door switch for locked door signals that the door has been unlocked during an on-going program. This can be caused by for example a bad or defective door lock, loose cable to door lock, problem with door lock edge connection.
11:4 WATER LOW TEMP	This error code is displayed if the temperature around the temperature sensor is below approx. -9°C. A low temperature means that the resistance in the sensor is too high, above approximately 23.7 kO. This can be caused if the machine for example has been standing outdoors, an open circuit in the sensor, a break in the cable to the sensor.
11:5 WATER HIGH TEMP	This error code is displayed if the temperature around the temperature sensor exceeds + 98°C. A high temperature means that the resistance in the sensor is too low, lower than approximately 350 Cl. This can be caused by for example a short circuit in the sensor, break in the cable to the sensor, etc.
11:6 WATER IN MACHINE	This error code can only arise in the case of rapid advance to the end of the program or if program is aborted. This error code will also appear if the level system has not indicated “empty drum" within a certain time (approximately 3 min). This time may vary depending on the size of the machine. Action • Check drain for dirt. • Blow through the level hose and check that it is not blocked and does not contain any water. • Check in the service program that the level control is working correctly. • Check for detergent overdosing.
11:8 NO HEATING	This error code is displayed if the temperature is rising too slowly when heating is active. The limit for this error code is normally set to a water temperature increase of approximately 3°C per 10 minutes but can vary depending on the type of machine and software. This error code can be caused by for example a defective heating element, a break in the power supply to the heating element, defective heating contactor, etc. On machines built for washing mops, it can be caused by too low level in the program step. The lowest level for a mop program in the main wash with heating is 90 scale units.
11:9 DRUM OVERFILLED	This error code will be displayed if the drum has been filled with water above a pre-determined level during an on-going program. This error code can be caused by for example a blocked level hose, drops of water in the level tube, defective filler valve, defective electronic filler control, etc. Action • Blow through the level hose and check that it is not blocked and does not contain any water. • Check in the service program that the level control is working correctly. • Check using the service program that all the water valves are working correctly.
11:10 DRUM NOT DRAINED	This error code is displayed if the water in the drum is not below a predetermined level when a drain period has been completed in the program. This error code can be caused by for example a blocked drain, blocked level hose, a water drop in the level hose, defective level control, restricted drain lines to the machine, too many machines emptying simultaneously into drain pipes that are too narrow, etc. Action • Check the drain installation and that the waste water can flow freely out from the machine without any restrictions. • Check the drain valve in the machine with regard to dirt. • Blow through the level hose and check that it is not blocked and does not contain any water. • Check in the service program that the level control is working correctly.
11:16 TIMEOUT HEATING	This error code is based on degrees/minutes. A check is made during water filling. If there is a drain leakage there will be repeated fillings and therefore no error code from gradient check. This timeout is an overall timeout that is started when heating is started. If heating time is longer than set in max heating time (Config 2) this error code will be displayed.
11:17 DOOR LOCK	This error code is displayed if the door lock is locked at the start of the program, i.e. that the door is locked although the timer has not requested locking.
11:27 LEVEL OFFSET	This error code arises if the level system indicates a level at the start of the program (when the drum should be empty) that exceeds what the program unit can compensate for automatically. This can be caused by for example blocked drain, blocked level hose, a drop of water in the level hose, leaking level system, defective level control, etc. Action • Check drain for dirt. • Blow through the level hose and check that it is not blocked and does not contain any water. • Check in the service program that the level control is working correctly.
11:28 WATER LEVEL HIGH DLCU LEVEL LOW	The DLCU on I/O type 10 contains a mechanical level guard which ensures that there is no water in the machine when the lock opens. To ensure that the level guard functions correctly, the mechanical level guard is compared with a nominal value generated by the level system, which is compared with the electronic level sensor. When the water level exceeds the nominal value during first fill, a check is made to ensure that the mechanical level guard is switched on, and if not, this error code is displayed. Cause • The level control can be damaged. • Cross talk in the level control electrical system. • Leakage in the level controls’ air hoses. • Incorrect nominal value, possibly caused by a error in the electronic level control. Action • Check the level control function. (Switch-on level = 40 mm, switch-off level = 15 mm Wg). • Check the cables and their connections. The voltage across the level controller should be 0 V when the water level is < 15 mm Wg and 5 V when water level is > 40 mm Wg. • Blow through the level hoses and check that they are not blocked and does not contain any water.
11:29 WATER LEVEL LOW DLCU LEVEL HIGH	The DLCU on I/O type 10 contains a mechanical level guard which ensures that there is no water in the machine when the lock opens. To ensure that the level guard functions correctly, the mechanical level guard is compared with a nominal value generated by the level system, which is compared with the electronic level sensor. When the mechanical level monitor is switched off during draining, the water level in the drum must be below the nominal value measured by the electronic level control. Cause • The level control can be damaged. • Cross talk in the level control electrical system. • Leakage in the level controls’ air hoses. • Incorrect nominal value, possibly caused by a error in the electronic level control. Action • Check the level control function. (Switch-on level = 40 mm, switch-off level = 15 mm Wg). • Check the cables and their connections. The voltage across the level controller should be 0 V when the water level is < 15 mm Wg and 5 V when water level is > 40 mm Wg. • Blow through the level hoses and check that they are not blocked and does not contain any water.
20:1 O.H. DRUM MOTOR	Not valid for washer extractors with MCU. This error code is activated if the overheating protection for the drum motor has trigged. The overheating protection is automatically restored. When the overheating protection is restored the error code is automatically reset and the ongoing program will continue. A long press on the control knob/start button will make the CPU reset and ongoing program will be ended. The error code can be trigged if: The motor is very warm. Check that the vent holes in the motor are not covered. If the overheating protection is not trigged, but there is still an error code: Check the harness, connectors and functions by reading the electrical schematic and by using the show inputs menu when the machine is in service mode.
20:2 NO MOTOR COMMUNICATION	This error code arises if the first message sent from the CPU to the MCU was not replied to during start up. Action • Check that there is power reaching the MCU. Check the fuses in the Protection Cable. If one of the components in the Protection Cable is damaged, the cable must be replaced. • Check that the indicator LED on the MCU is on. The LED can be seen by looking down by the MCU edge connections. • Check that the communication cable between the CPU board and the MCU is intact and not damaged. Measure also with a reference instrument to see whether there is contact between all the leads in the communication cable.
20:3 LOST MOTOR COMMUNICATION	This error code arises if the communication between the CPU and the MCU has stopped working. Action • Check that there is power reaching the MCU. Check the fuses in the Protection Cable. If one of the components in the Protection Cable is damaged, the cable must be replaced. • Check that the indicator LED on the MCU is on. The LED can be seen by looking down by the MCU edge connections. • Check that the communication cable between the CPU board and the MCU is intact and not damaged. Measure also with a reference instrument to see whether there is contact between all the leads in the communication cable.
21:1 HEATSINK TOO HOT	This error code is generated by the MCU. There is a temperature sensor (NTC) mounted on the MCU cooling flange next to the power transistors in the output stage. If the temperature of the cooling flange gets too high (> 90°C) the error code will be set to protect the transistors. The cause of high cooling flange temperature can be e.g. a stiff drum in combination with intensive use and high ambient temperature. There may also be an error in the motor (sticking bearings or short circuit in windings, which impairs the efficiency of the motor). Action • Make sure the drum turns easily. • Check the value on the error code counter for the error code. • Check the last 8 MCU error codes. • Start a 90°C normal program with load on continuous operation and measure the temperature of the motor and MCU. • Replace the defective part.
21:2 MOTOR TOO HOT	This error code is generated by the MCU. Each time the motor is started from stationary, the MCU will first measure the resistance between two phases in the motor. The MCU processor governs the output transistors so that a DC current flows between two phases in the motor winding. The actuation of the transistors is a measure of the voltage applied to the winding and the resistance can be calculated using the current and voltage values. The resistance can then be converted to a temperature since the winding resistance at 20°C and the temperature coefficient are known. If the average value of the four latest temperature readings is higher than the maximum motor temperature (e.g. 150°C), the error code will be activated. The cause of high motor temperature can be a stiff drum, possibly in combination with intensive use and high ambient temperature. There may also be an error in the motor (sticking bearings or short circuit in windings, which impairs the efficiency of the motor). There could also be a contact error in the connectors between the MCU and the motor or an error in the motor cable. An error in MCU temperature measurement circuits can also occur. Action • Make sure the drum turns easily. • Check the value on the error code counter for the error code. • Check the last 8 MCU error codes. • Measure the three phases to the phase resistors on the MCU motor connector (disconnect MCU and take the reading in the cable connector) to make sure they are the same. • Start a 90°C normal program with load on continuous operation and measure the temperature of the motor and MCU. • Replace the defective part.
21:3 NO INTERLOCK	This error code is generated by the MCU. The MCU must be powered with 230V / 50 or 60 Hz on the interlock input in order to drive the motor. This signal is a confirmation that the door is closed and locked. MCU receives its commands to rotate the drum from the CPU via a serial communication link between the MCU and CPU. Since the CPU also has access to the interlock signal, the CPU must never send a run command to the MCU if the interlock signal is missing. If this does happen, this error code will be activated. The cause of this error code being activated can be e.g. a break in the cable leading the interlock signal to the MCU. There may also be an error in the connector in the door lock, which connects 230V / 50Hz to the interlock signal. An error in the interlock circuits of the MCU can also set this error code. Action • Use a measuring instrument to check that the interlock signal comes on X302:1-2 when the door lock is activated. Read also bit 1 in the second byte under "Motor Status" in the service program (the bits are numbered from 0 to 7 where bit 0 is on the far right). If bit 1 in the second byte is 1 then the lock is open, while a 0 indicates that the lock is closed. • Replace the defective part.
21:5 MOTOR SHORT CIRCIUT	This error code is generated by the MCU. The MCU reads the power consumption of the motor continuously. If the current for some reason gets too high (= exceeds a certain limit), the MCU will cut the current to the motor. After the motor has stopped (= tachometer indicates stationary motor), the MCU will attempt to restart it. If the MCU then detects high motor current again, this error code will be activated. If on restarting after a first short circuit, the MCU rotates normally, an error code will not be activated. Cause This error code can be activated for a number of reasons: • Short circuit in motor. • Short circuit internally in motor winding (impaired efficiency, higher current consumption). • Short circuit in motor cables. • Short circuit in connectors. • Drops of water causing short circuits in the motor connector. • Short circuit in the MCU output transistors. • Bad contact in tacho signal. • Bad contact in interlock signal.Action If the error is a stable one, it is generally not difficult to locate the defective unit through resistance measurement and testing with the service program. Further information can be obtained by studying the contents of "MCU FAULT LOGGER". Study the following: • SHORT CIRCUIT 2 (specifies how many times the error code has been active). • SHORT CIRCUIT 1 (specifies now many times the current limit has been exceeded. The difference between short circuit 1 and short circuit 2 indicates how many times there has been a short circuit 1 that has not been confirmed when restarting the motor). • LAST FAULT CODE N/8 (shows the 8 latest error codes). • TACHO CUT-OUT LOW RPM (can give a clue in case of intermittent errors). • TACHO CUT-OUT HIGH RPM (can give a clue in case of intermittent errors).
21:6 INTERLOCK HARDWARE	This error code is generated by the MCU. The MCU must be powered with 230V / 50 or 60 Hz on the interlock input in order to drive the motor. The interlock circuits in the MCU have been split into two channels so that a component error in MCU cannot give a false confirmation that the door is locked. These two channels are checked against each other. If this check gives an incorrect result this error code will be activated. The reason for this error code being activated can be attributed to an error in the interlock circuits in motor control. Action • Replace MCU.
21:7 LOW DC VOLTAGE	This error code is generated by the MCU. The MCU constantly measures the voltage over the mains input. If the voltage is too low (= falls below a certain limit), the MCU will shut off the current to the motor. Once the motor has stopped (= the tacho sensor indicates that the motor is stationary), the MCU checks to see whether the input voltage is still low. If it is, this error code is activated. The reason for this error code being activated can be low mains voltage or that the machine’s on/off switch has been operated in an unsuitable manner. Further information can be obtained by studying the contents of "MCU FAULT LOGGER": • UNDERVOLTAGE 2 (specifies how many times this error code has been active). • UNDERVOLTAGE 1 (specifies how many times the voltage has dropped below the limit. The difference between undervoltage 1 and undervoltage 2 indicates how many times there has been an undervoltage 1 without it being confirmed when the motor has stopped). • LAST FAULT CODE N/8 (shows the 8 latest error codes) Undervoltages can be registered even during normal operation. Consequently, a small number of registrations need not mean that there is an error in the MCU. Action • Check that the supply voltage is stable and never drops below nominal voltage -10%. • Check the fuses and cables. • Check the supply voltage in the network cabling and at the MCU in the machine.
21:8 HIGH DC VOLTAGE	This error code is generated by the MCU. The MCU constantly measures the voltage over the mains input. If the voltage is too high (= exceeds a certain limit), the MCU will shut off the current to the motor. Once the motor has stopped (= the tacho sensor indicates that the motor is stationary), the MCU checks to see whether the input voltage is still high. If it is, this error code is activated. The reason for this error code being activated can be high mains voltage (e.g. power surge). Further information can be obtained by studying the contents of "FC FAULT LOGGER": • OVERVOLTAGE 2 (specifies how many times this error code has been active) • OVERVOLTAGE 1 (specifies how many times the voltage limit has been exceeded. The difference between overvoltage 1 and overvoltage 2 gives the number of times overvoltage 1 has occurred without it being confirmed when the motor has stopped). • LAST FAULT CODE N/8 (shows the 8 latest error codes). Overvoltage registrations can also occur if there is a bad contact in the tacho signal. Check also the following registers: • TACHO CUT-OUT LOW RPM (number of short tacho interruptions during wash rpm). • TACHO CUT-OUT HIGH RPM (number of short tacho interruptions during extraction rpm). Action • Check the tacho cables if there are many registrations in the TACHO CUT-OUT registers.
21:15 MOTOR NOT FOLLOW	This error code is generated by the MCU. The MCU must always receive information on the rotation of the motor from the tacho sensor in order to rotate. If the tacho sensor is not working, the motor can rotate for max. 10 seconds during the starting process. After this period, this error code will be activated. Cause • Break in the cables between the tacho sensor and the MCU. • Break in connectors in tacho cables. • Break in one of the phases to the motor (cables or connectors). This error can be suspected if the motor does not rotate for 10 seconds (the motor will not start with only two phases). • Error in tacho generator. • Error in tacho circuits in the MCU. Further information can be obtained by studying the contents of "FC ERROR LOGGER”. Study the following: • MOTOR NOT FOLLOW (specifies how many times this error code has occurred). • LAST ERROR CODE N/8 (shows the 8 latest error codes). • TACHO CUT-OUT LOW RPM (can give a clue in case of intermittent errors). • TACHO CUT-OUT HIGH RPM (can give a clue in case of intermittent errors). Action • Replace the defective part.
21:20 NO PARAMET. SET IN MCU	The program unit has read from the MCU or I/O board that the interlock is not active. The reason for interlock failure can be a problem with the hatch lock, damaged motor supply cables or the I/O board with interlock voltage etc. The most probable error source is the I/O board.
40:1 I/O BOARD MISHMASH	The error code is activated if wrong I/O board is adressed to wrong position in the machine. After addressing of I/O boards the CPU reads the type of board in every position. If there is a mishmash between what the CPU reads and what the software expect on any address the error code will be displayed. Readdress all I/O boards. Use the electric schematic to find correct I/O board to address.
40:2 I/O INTERLOCK	The program unit has read from the I/O board that the interlock is not active. The reason for interlock failure can be a problem with the hatch lock, damaged motor supply cables or the I/O board with interlock voltage etc. The most probable error source is the I/O board.
40:21 I/O COMMUNICATION	The error code is activated if the CPU no longer communicate with one or more I/O boards. There is an internal data bus between the different I/O boards in the machine with information about inputs, outputs, etc. that the CPU use to control the machine. The error code is activated if the CPU has lost communication with one or more I/O boards. The error will also be activated if the service button is pressed on the wrong I/O board during configuration of I/O boards. If there is communication between the I/O board and CPU the LED next to the service button will flash. If there is no communication to the I/O board but power, the LED will light when the button is pressed on the I/O board. Check that all I/O boards are configured in i/o configuration menu when the machine is in service mode. If all I/O boards present in the list check the LED and harness, connectors and functions by reading the electrical schematic.
41:1 CHARGE CIRCUIT	The DLCU on I/O board 10 contains an arming circuit that is charged when the door lock coil is to be activated. For safety reasons, this arming circuit must be discharged when the door lock coil is not to be activated. If the arming circuit for operating the door lock is charged when it is not supposed to be, an error message will be sent to the CPU. If the error ceases, the message will not be sent to the CPU. CPU reads the error message when the door is locked and unlocked and generates an error. The error is ignored between these two occasions. Cause • The error can bee caused by overloads and/or defective components in the DLCU on I/O board 10.
41:2 SET SIGNAL NO TACHO	The DLCU on I/O board 10 counts the tacho pulses from the motor in order to guarantee that the drum is stationary when the door is opened. To ensure that the signal from the tacho generator is working correctly, DLCU compares the tacho signal to a digital bit value from the CPU, which is due to the CPU having activated the motor. The tacho signal should always correspond to the digital bit value and if the tacho signal is not present when the digital bit value is present, an error message will be generated to CPU. The error message is filtered in such a way that the digital bit value should have been on for 2 seconds; if this is the case, a check is made that the pulses from the tacho sensor are present when the digital bit value ceases. Internally the DLCU will automatically clear an error if it disappears during program run. CPU reads the error message when the program finishes and generates an error code, the error message is ignored between these two occasions. Cause • The error can be caused by breaks in the circuits for the tacho sensor, or caused by a error in the magnet in the tacho sensor. • Collateral damage due to a error in the motor system.
41:3 ACTUATOR CIRCUIT	The DLCU controls the door lock actuator coil. The DLCU checks continuously that the coil is engaged. DLCU can detect a break in the circuit (>50 kQ) (DLCU cannot detect a short in the circuit). If there is a break in the actuator circuit, CPU will be notified; the error code will disappear if the error ceases. CPU reads the error message when the program starts and finishes and generates an error code, the error message is ignored between these two occasions. Cause • The error can be caused by a break in the cables between the hatch lock and the I/O board 10, or caused by a error in the hatch lock solenoid. • Error or break in the I/O board 10 circuits. Action • If the error returns after a reset, and is not caused by a error in the hatch lock or the cables for the hatch lock, change the I/O board 10.
42:1 INTERNAL ERROR	Reading of A/D values out of range.
42:2 POSITION TEST	Position value out of range. Check that I/O module type 6 is still in correct position.
42:3 EXTRACT TEST	I/O module type 6 is not able to read any or too low values during extraction.
51:22 NO CBT COMMUNICATION	Machine with payment system using serial communication to machine. Serial communication with payment system interrupted. Check network cable between machine and payment system. Check that payment system is operational.

Error codes of washing machines are necessary in order to simplify the diagnosis. Using them, we will easily understand what is out of order in our household appliances.
