Justin K for Model Number GDF520PSF4SS I am still having trouble with a g.e dishwasher.This is my second letter to your on it.I followed everything your told me to do on first letter and still having problems with it.The problem is the dishwasher is not drying the dishes.I will give your a quick run down of what your told me to check last time and what i did.Your told me to check out the machine control.with the wires connected to heater,J702 test from violet wire to red and white wire for 23.4 ohms.I did that and my unit was dry and i got a ohm reading of alittle over 21 ohms.your originally said if resistance shows open but was showing good at heater then Tco on a/c wire harness and pump kit has failed.But my resistance was not open and i did disable the heat strip and test it by itself and it tested good.The last thing your said in first letter was if reading is good at two wire points the machine control would be cause of problem and my readings were alittle lower than 23.4 ohms but nothing in resistance was open or did heating element show bad.So i replaced main control board and heating element due to ohm reading being alittle low and dishwasher is still not drying the dishes.Could your please direct me to what else i need to check when i ran them both times before replacement of parts and then after the replacement of the parts i check for power at heat element and amperage when it goes into dry mode and i get no voltage or amperage,so the heat element is not coming on or trying to come on.One thing to mention is i am running dishwasher on a cold water supply line instead of hot water supply line.Could this be causing my problem or could it be something else. Your help again on this dishwasher would be so so greatly appreciated.Thanks for your time once again.
Answer Justin, You will want to have the dishwasher set up on a hot water line as the unit would not be able to heat the water to the proper temperature. Hot water coming to the dishwasher is one of the most important aspects of getting clean dishes and them drying. Read More... Answered by AppliancePartsPros.com | Thursday, October 27, 2022
