Repairman didn't reset my error 3 code

If during the water heating step in the wash cycle, the water temperature sensor (NTC) value is out of range, or the heating element circuit has failed, the F05 error code will be displayed. Might need to be taken to a repairman

The "F01" error code is indicating a communication error between the Central Control Unit (CCU) and the EEPROM on board the CCU occurred. Generally in order to correct this failure the CCU board will need to be replaced.
Before you cal the repairman, try unplugging the washer for 3 minutes and then power up again and see if the error clears.

Good luck.

i think the engineer has unpluged it. check that its plugged in at the back when he or she put it back together they would of unpluged it from the socket to put the cover back on.

You need to set DIPSW 3-1 to 0. You need to boot into mode 25 to do this. If you didn't fix the problem in the fixing station that caused this it could be bad.

Hello

Try pressing pause and cancel twice.

Then restart the washer.

I had this same problem with mine, i unplugged it and pushed the reset button on the side and now it's working fine.

“F21” (AKA SD) is a Long (SLOW) Drain error (LD). If the drain time exceeds 8 minutes this error code will be displayed. In addition, a “SUDS” error may also be displayed. This may be an indication of a drain pump problem and/or clog in the drain line. You will need to check the following:


1.First, attempt to unplug the washer for at LEAST 30 minutes to reset the Central Control Unit (CCU). Sometimes this is all that is required to correct momentary glitches with the unit. If the error code returns, proceed to step 2.
2.Check the drain hose to make sure it is not kinked or clogged.
3.Check the electrical connections to the pump and ensure the pump is running.
4.Remove the drain pump filter and check for foreign objects and/or debris.

If the above procedures do not correct the problem, it is recommended by the manufacturer to replace the drain pump.
