I had a call today about this dishwasher that no matter what program you select it gets too hot, even the rinse cycle gets boiling hot. The customer told me it takes an hour or so for the machine to cool down again. Does anyone have any info/ wiring diagram for these machines?
if this was a beko made machine then occasionally i get called to circuit boards where the heater relay has stuck in the on position. a good clue is switch it on at the panel and without selecting or starting a cycle, you will hear the water in the heater start to boil. checking the relay would of course apply to other brands but not as common. i believe yours is a Haier
