I’ve had a Diplomat ADP 8640 Dishwasher for 4 years now and I must say it’s been brilliant..
However it has now begun going through the washing cycle but not heating the water.
Can anyone tell me, Is it simply a case of changing the heat exchanger which looks straight forward enough or could it be a more sinister problem?????
Have you checked the heater to see if it is open circuit, that would be your first thing to check if its open circuit then you have found your problem if its ok then you may have a break in the wiring or even maybe a faulty timer. The machine you have is actually a whirlpool machine and to be honest the heaters are usually ok, have a check then let us know.
