DETERGENT MODULE WD12X32799

I pulled the dish washer out and, make sure you turn off the power, disconnect the water and drain line. un screw the mounting screws.
The first thing i checked was the drain filter which was clogged. I took shop vac and sucked all the excess water out and removed the flood switch. seemed ok but you can't tell if its ok, so just r ... Read more eplace it. I then removed the door from the unit. I needed to replace the dispenser. After the door was off I tilted the machine forward, to check the heater. I pulled the quick connects off and checked the resistance across the heater, should be 16 ohms mine was 16.3 so heater not bad. looking at the bottom of the machine, follow the left hand wire and it will attach to a thermal overload. (a small round disc which is not listed in the parts manuals ), I checked for continuity across the switch it was open.
On this model GE the switch is resettable, a small reset button in the middle of the overload. I reset it and continuity was restored. only three things might cause this to kick. one the flood switch, the vent fan or the turbidity sensor. I replaced all three and the machine is working great.
If you have replaced your heater and still doesn't heat, try resetting that switch. and give GE a big thank you for not telling any one about the switch.
A big thank you to PartSelect for having all the correct replacement parts.
