HI gents
have an indesit dishwasher shows AO2 not on every wash might take a week or two to show this fault .Have changed pcb hopeing to rectify lasted 2 monthes customer says water is getting hot but has shown AO2 again any ideas model DE73
cheers alro
That means you have to check:
– heater relay from board (not to be stuck/jammed ON)
– heater (intrerrupted or broken/leakage to mass/earth)
– safty thermostat (OFF/OPEN) (*also thermistor to be in his position/with thermal paste for good temperature transfer)
IIRC had this before where the customer used to put a large pan in the dishwasher which blocked the water spray to the area of the temperature sensor. This gave an incorrect reading. Very intermittent fault but stopped when she stopped putting the pan in that position. :rolls:
