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.
