How to replace board control - Washing Machines

It's possible that the issue is with the control board and not just the control panel. Before replacing the control board, here are a few things you can check:

1. Make sure the control panel is properly connected to the control board. Check the connections and make sure they are secure.
2. Check for any damaged wires or connectors. Look for any signs of damage, such as frayed wires or loose connectors.
3. Check the voltage to the control board. Use a multimeter to check the voltage at the control board. If there is no voltage, there may be an issue with the wiring or power supply.
4. Check the fuses on the control board. If the fuses are blown, the control board will not function properly.

If none of these steps resolve the issue, it's possible that the control board is faulty and needs to be replaced. However, it's important to note that diagnosing and repairing electrical issues can be dangerous and should only be attempted by qualified professionals. If you're not comfortable working with electrical components, it's best to seek the help of a certified technician.

F1 - Control Board Failure - Replace control board (ERC). F2 - Oven Temperature Too Hot - Replace oven temperature sensor. F3 / F4 - Shorted or Open OvenTemperature Sensor - Replace oven temperature sensor. F5 / F6 / F8 - Control Board Failure - Replace control board.

Communication problem. Check the wiring between the Main
Control Board and the Speed Control Board. Wiring bad, correct wiring problem. Wiring good, replace the Main Control Board. If the problem is not corrected, replace the Speed Control Board.

I assume that should be "SC400"... This is an error which can be reset by turning the MAIN power switch off for a few seconds and then on. The code will be cleared, provided the problem does not happen again.

SC400 - Image transfer belt bias error

Detected Conditions:
- Timing -
While the image transfer belt bias is ON
- Condition -
The feedback voltage is 4.8V or higher, or PWM value is 50% or higher for 500ms continuously.

Possible Causes:
• Poor connections
• Defective high voltage supply board (T1/PCC/BR)
• Defective I/O control board
• Defective main control board
• Worn Transfer Belt

Troubleshooting Procedure:
1. Make sure the high voltage cable and trigger lines are properly connected to the high voltage supply board, I/O control board, and main control board.
2. Replace the high voltage supply board (T1/PCC/BR).
3. Replace the I/O control board.
4. Replace the main control board.
[Signal Check]
• Feedback signal: CN209-9, TP264, or CN211-A4 on I/O control board / CN302-A6 or TP106 on main control board.
• PWM: CN209-10 or TP272 on the I/O control board.

I think I figured this one out. I think it means that the washer is not able to drain, therefore it won't spin either. Underneath the washer is a series of outlet hoses and within one of them is a filter. When I finally found the filter it was clogged up with lint, fibers from a pillow and coins. You have to dig the filter out and then clean the filter and rehook up the hoses, this was relatively simple even for me. The washer works perfectly now.

I WOULD SAY REPLACE THE PRESSURE SENSOR IF BOTH CONTROL BOARDS HAVE BEEN REPLACED

THE MOST ECONOMICAL PART ASSOCIATED WITH THE CONTROL BOARDS ESPECIALLY AFTER HAVING ELECTRICAL PROBLEMS IS MORE THAN LIKELY THE PRESSURE SENSOR it may have BLOWN ALSO
