Sorry for the delay in getting to you, I've only just logged on and seen your question waiting.

If you have repaired the fault on the machine then the reset procedure in the service manual is as follows.

Close the door -

Set program selector switch to position 0 ("OFF") -

Set program selector switch to position 8 (6:00 o'clock) - W

ait until the start LED is flashing.LED Start/Pause is flashing -

Actuate and hold the “Spin speed” button -

Set program selector switch to position 9 (turn clockwise)state LED’s and seven-segment display are illuminated for a period of 3 sec -

Release the “Spin speed” button.

Turn to off then back on.

You may have to do this several times to clear all errors in memory.

Hope this helps

Just ignore the flashing light part, keep trying the reset.

If it won't clear, then it would suggest a damaged board or motor and a new code is being generated.

Let me know how it goes.
