Re: Siemens WTXL720CGB/01 won’t start
you say it switches off ?
long shot check what sort of power supply they use on the board. if its a series capacitor then when motor relays kick in the board power supply might fail causing board to crash
also i would measure voltages on board motor relays to see if the board is trying to turn then on. Relays on board fail quite a lot and it not unusual to put 8 volts or so on a 12v relay. when its new it works but as with any mechanical device it wears and fails with age
hope it helps more than my previous entry
