Our 8 year old machine, suddenly started emitting a constant high pitched noise similar to faulty PC motherboard. Nothing works, no lights illuminate and turning off the breaker for 30 seconds plus does not rectify the problem. Do I need to replace the module control?
You will want to do a voltage check to the control board. If the control board is getting 120vac and there is no display then check to make sure that the ribbon harness is fully seated. If all checks ok then the control board is more than likely faulty and needs to be replaced.
GE d/w has erratic display. Cycle times change , as cookware function will sometimes be 121 minutes --116 minutes. Normal wash function also has erratic times displays. Does the control module WD21x10215 need replacing, if so what is involved in the replacement process. Thank you for your help.
Answer Travis, you may not need anything at all. Your dishwasher is probably working "normally". Your dishwasher is equipped with sensors that react to temperature, suds, turbidity, etc. These sensor inputs to the control will extend or shorten the cycle as needed. You may want to start and run the most commonly used cycle empty no detergent etc., this will reset the sensor and control and return to the baseline cycle.
Dishwasher going through cycle but not dispensing detergent until dry cycle evidently sense detergent capsules are evidenced in the bottom of the d/w after cycle complete. Do I need a whole new module?
Answer Jerry, You may not need a module at all. First thing to check is the amount of water in tne bottom of the tub. Start the dishwasher and allow to run for five(5) minutes, then unlatch and open the door, remove the lower rack and check the water temperature(120 dgrs. minimum) and water level " Amount of Water – Make sure dishwasher is level. Check water level, allowing dishwasher to fi ll normally for fi rst fi ll. The water level should be to the center of the bottom of the fl oat dome. If water level is low, check for clogged screen in water valve and check float switch." Low water level and or low water temp. can give the impression of not operating properly. Allow the dishwasher to run the complete cycle and make sure the dishwasher fills and drains properly and the drain system is not syphoning the water out of the tub during the cycle.
