My dishwasher runs fine until it gets to the dry cycle. It starts to beep and the drying cycle does not run. I changed out the sequence switch but it did not help. Does the control board need to be replaced?
You will want to check your heater circuit to make sure that it is working properly. Make sure that your heater is good and that any thermostats for the heater are good. If these check ok then the control board would be faulty and need to be replaced.
My GE Triton dishwasher is about 7 years old. We don't use it very often, but recently it stopped actually washing the dishes. The water fills up in the bottom, and then it makes some normal "wash cycle" noises, but the water never actually pushes through the spinning wands to wash the dishes.
I am wondering what part may have failed.
Answer Brian, First check to make sure there is enough water in the bottom of the tub, Start and allow the dishwasher to fill and wash for 3 to 5 minutes, the water level at that point should be 1/4 to 1/2 inch up from the bottom of the float dome, in the left front corner. If not, there's not enough water in the tub to operate the pump and wash the dishes properly. If the water level is in range, and based on your information, you would need to check the fiilter WD22X10043, sump filter WD22X10021,and sump cover WD12X10040 for debris and deposits clogging the system, and not allowing the water to flow and return to the pump assembly. If all's OK, you'll need to remove the pump/motor assembly, and check the impeller assembly for danaged vanes WD19X10032 Damaged vanes won't pressurize the pump, and water can't be driven up to the spray arms.
How do I know if I need a new control board or a new sequence switch? The problem is the dishwasher doesn't drain. There is no voltage going to the drain pump during the drain cycle. However, when I ran a diagnostic test, the drain pump did pump out the water. So I know the drain pump is OK, and I know the hoses are clear.
Answer Hi Brad. Put the drain hose (loose from the sink) into a bucket and advance unit into drain. Look at the end of the sink drain and put a screwdriver in it to make sure it is also clear. Remove the drain hose from the pump and see if there is something in the pump impellers. Take the top cover grills in the tub off and see if there is anything in the holes that clog it. You have to check the drain pump power wire at the board for 120 vac out put to ground or neutral (white wire). Remove all top pieces from the lower wash arm down and make sure all is clear. Make sure the opening at the rear of the tub where the dirty water collects, that the chopper blade is freely working. Thank You.
