For some reason the heating element on our dishwasher is not coming on during the wash cycle. I used the diagnostics to confirm that the element works, but the unit will run through a cycle and not heat up no matter what settings we use. We normally use the heavy wash function with steam, sanitize and heat dry so the element should definitely be coming on. I replaced the wash pump kit a few months ago and used all the new wiring harnesses. It worked normally for a few months until last week. At first I thought maybe the element had just burned out because it had been run a few times before we realized that the wash pump was dead and I thought maybe it overheated. As far as I can tell this unit doesn't have a replaceable thermostat or thermistor anywhere. I'm thinking it must be the control board, but if the element will come on during the diagnostics, whatever on the control board turns the element on is obviously still working. I've seen some comments online that the turbidity sensor or float sensor can affect the heating, but, at least from what I can tell, those appear to be OK and most claims of those being the culprit seem to be overturned by a technician online.
Before I drop $175 on a new control board I'd like to exhaust any other possible options. Still cheaper than a new dishwasher, but still
