ok went to a Beko washer dryer which came up E00 on odd occasions
would not fault for me on day one but was a bit noisy. On taking the lid off the power board had snapped the holding bracket and was hitting the drum so I costed and orderd a new board as the the box that the board sits in only comes with it
Went back today. fitted new board and pressure hose as that was partly rubbed through. Turned on, set a programme and the machine faulted out E00 instantly. Tried swopping old board back as the old board was fine it was just case damage, result no change. tried the old favourites and disconnected elements, still no change. then as i was playing one of the wires connected to the pressure switch broke off. I set about and managed to solder this wire back into the plug, reconnected and hey presto all now working
so a broken wire to the level switch will give you E00 fault
not sure if any other circuit problem will do the same but check this first
