GE Dishwasher GDT680SSH8SS will not heat water or dry
« on: July 29, 2019, 10:04:30 PM »

Hello everyone, I have a GE dishwasher model no. GDT680SSH8SS that won't heat the water or dry dishes.  I disconnected the wine colored wire connector on the electronic control board and hooked up the two wires to a cheater cord, plugged it in and the heater got hot so I know the heater& tub thermostat are OK.  I replaced the electronic control board wd21x24797 but it still does not heat.  I see on line that some models have a hidden heater in the pump module and I will check that tomorrow.  I can't find the mini tech sheet in the dishwasher.  If you know the service manual part no.  I'll be able to get it online.  Also do you know if the new electronic control board needs to be programed to this model?  If you can help, please let me know.  thanks!!!

I see a lot flood float switch assembly, part number WD21X10519 can cause no heat problems. Here is the Mini Manual.

Hey dab147315,  Thanks for you advice on fixing this dishwasher,  I reinstall the customers old electronic control board, checked the heater with my meter (good) replaced the tub thermostat that came as a wire harness only and replaced the flood float switch as you told me to.  The dishwasher now heats great in the dry cycle too.  Thanks again for all your help!!!
