Re: AEG LAVATHERM 3300W
From what you add then I can only assume the control module at fault in that the relays on the board are sticking maybe? Maybe you could try tapping the PCB during the period the motor is not energised to see if it bursts into life. Or remove and check the Rast connection blocks to the timer/module unit? 😕
Interestingly, the service manual is less than specific on this issue, the wiring diagram drawn up by some maniac professor from his prison cell by the looks of it. So no help there I’m afraid. 🙁
