Appliance switches on and starts, but switches itself off at varying stages during the cycle and the display disappears. This is on the automatic drying side of the cycle. The customer is trying it on the timed drying side as a comparison. Once it is switched back on and restarted, it will go off again at varying stages. There is no pattern in the timing that it switches itself off. I am suspecting the door interlock as a possibility. has anyone had this experience? Cheers for any assistance. Much appreciated as usual. Steve.
