Diplomat ADP 8242 3Flashing lights and the last light stays on?

About three months ago I got an error code combination that was not described in the user manual. I called the engineer out and it took him 2 minutes to reset the washer.
It seems this washer has an overflow sensor setting on the pcb but is not fitted with the sensor hardware! I got error lights showing 1, 2 & 3 flashing and 5 on constantly.
After a power cut, the same error happened again so I tried the following reset.
Turn off at the power button and leave for 10 seconds.
Turn on power button and press the program button 4 times
I found that you had to be very quick pressing the program button four times after powering up. You know you've hit it right when then two outer lights stay lit.
Then push the program button once.
Then power off (without closing the door).
Wait 15 seconds then power up and the reset should have taken place.
