Hi,
My dishwasher stopped heating water, replaced through flow heater and thermostate, washed once heat OK, stopped after that. Any clues what else should be replaced?? Any idea how to retrieve any foult codes as this is one swith only operation.
you need a multimeter on the ohms scale and you would expect a reading under 100 ohms if its ok. take the wires off the heater and measure between the terminals
if its blown then its either
A fault which is rare
B the heater is coming on with no water in it which is a timer problem
