REPAIRING AND NOT THROWING AWAY

Richtige Fernseher haben Röhren!

In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!
Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

SAMSUNG WF6450S7W - WASHING MACHINE - ALIGNMENTS AND ADJUSTMENTS - ERROR CODE DISPLAY

SAMSUNG WF6450S7W - WASHING MACHINE - ALIGNMENTS AND ADJUSTMENTS - ERROR CODE DISPLAY


DRIVING COMPARTMENT TEST MODE
  • Hold down “1” and “2” keys simultaneously and then press POWER S/W “4” on.  (Whole lamps turn on and display show “t1” after 2 Seconds.)
  • The driving compartment can be tested when you press “3” key right after entering into the initial stage of the TEST MODE.
DRIVING COMPARTMENT TEST
Pre-wash VALVE ON(0.3sec) → OFF(0.3sec) → COLD VALVE ON(0.3sec) → [OFF(0.3sec) → HOT VALVE ON (0.3sec):OPTION ] → OFF(0.3sec) → Pump MOT OR ON(0.3sec) → OFF(0.3sec) → MOTOR Left (1.0sec) → OFF(0.5 sec) → MOTOR Right (0.5sec) → OFF(0.3sec) → HEATER RELAY ON(0.3sec)→ OFF(0.3sec) → DOOR OPEN (Function continues when door is closed).

THERMISTOR TEST MODE
  • Hold down “1” and “2” keys simultaneously and then press POWER S/W “4” on. (Whole lamps turn on and display show “t1” after 2 Seconds.)
  • Press the “Delay start” key and display shows “t2”.
  • Press the “Start/Pause” key and display shows the inside temperature of tub.
An occurrence of an Error will make a sound of error melody for 5sec and continuously show one of the Error Displays from the following errors. (But, Fault Check Led will flash for 0.5sec.)
All of the steering parts will be off at that time until that error was released.
  • Water Supply Error
If there is no higher change in water frequency than 100Hz for 2 minutes during the initial time of water supply and if water level doesn’t reach the preset level in 10 minutes, this error will occur.  This error will be released using Start/Pause button, which performs the initial condition of operation. [ Display : “4E”]
  • Water Drain Error
If water level frequency is still lower than the reset level frequency (25.20kHz) in 10 minutes after starting of water drain, this error will occur.  This error will be released using Start/Pause button, which performs the initial condition of operation. [ Display : “5E”]
  • Over Flow Error
If an abnormal water level frequency is sensed (for occurrence of Over Flow :21.00kHz), Auto Power Off may release this error and continuously progress water drain until the frequency reached 25.00kHz.   If Over Flow is also sensed even after the following check of water level frequency indicating that error, it functions to progress water drain. [ Display : “OE”]
  • Door Open Error
This error will be released by closing Door. [ Display : “door”]
  • Unbalance Error
This error will be released by pressing start/pause S/W. [ DISPLAY : “ UE”]
  • Water Heater Error
This error will be released by turning off Power S/W. [ Display : “HE1”(Over Heat),] [ Display : “HE2”, indicating no operation of HE.]
  • Pressure S/W (Single Part Trouble) Error.
Frequency signals(kHz) generated by water level S/W.
Water Level
Low
High
Abnormal Frequency
30.00 KHz
15.00 KHz
If the above frequency signals are displayed longer than 5sec, it indicates Pressure S/W Error.   Drain water for 3 minutes for that Error, and turn OFF water drain pump. Pressure S/W Error display “ IE” will be shown.
  • Abnormal Water Temperature ERROR
Water drain begins if abnormal water temperature is sensed at the initial time of water supply. If the frequency higher than 25.20KHz is sensed, water will be drained by force. [ Display : “CE”]   This error will be released by turning off Power S/W.
  • Natural Drain/Water Leak Error
If more than 4 times of water supply and safe water level of Heater are sensed for each course, this error will occur. [ Display : “LE].   This error will be released by turning off Power S/W.
  • Tacho Error
If Motor Tacho is abnormal, this error will occur.   If Tacho signals are inputted less than 2 for 2sec after Motor started, this error will occur. [ Display : “3E”].   This error will be released by turning off Power S/W.
  • Motor TRIAC Short Error
If Tacho signals are inputted more than 300 every 1sec in the operational interval less than 90RPM, this error will occur.  Turn off Power S/W at that time. [ Display : “bE”].   This error will be released by turning off Power S/W.
  • Thermistor Abnormal Error
If Thermistor circuit is abnormal, this error will occur.  If Thermistor is lower than 0.2V or higher than 4.5V, this error will occur. [ Display :”tE”].   This error will be released by turning off Power S/W.
