Dishwasher has power to it but display does not work. Only button/feature that works is the start/cancel button so we can still wash dishes but do not know what mode it is in. Do I replace control panel or control board? Thanks
Answer Hello Glen,
You should first open the door panel to access the connection between the board and the control panel. If you cannot correct any electrical connections to eliminate the issue, the issue can be caused by the control panel or the control board. This can sometimes be determined by the visual appearance of the ribbon cable or the ribbon cable receptacle on the board.
Have power but have no lights on control panel.
Answer Hello Frank. You removing the ribbon cable and see if cleaning it with an eraser will repair the unit. If not, and the door switches are good, you will need to replace the control board on the unit. If cleaning makes some lights work, but not all, replace the touch pad in the unit.
Dishwasher will continue to run when door is shut. It will run for hours and hours. Washing and extra rinse indicators continue to blink (green light). Depressing any front panel button including washing and extra rinse does nothing for operation of the dishwasher. Dishwashing will only stop washing when door is opened. Request any assistance available.
You will want to check the turbidity sensor as the sensor may be faulty causing the unit to continuously run. To test the sensor, you will need to check at the control board on connector J5 pin 1 to pin 4. The sensor should be 10K at 77 degrees =/- 3% and 2.4K ohms at 140 degrees =/- 6%. When testing the J5 connector pin 1 to 4 0 ohms = closed and infinite ohms = open.
All the lights on the control panel work, I can select any option. I turn the washer on and it starts to wash then stops, it will start back up on its own then stops again. It usually takes 24 to 48 hours to complete a wash cycle. What should I replace?
You will want to check to make sure that the power supply wire to the dishwasher is at least a 12 guage but you could go with a 10 guage. If the wire is too small it could cause it to heat up and cause an over current. You will also want to check to see if the motor is getting constant voltage of 120 vac. If it is then the motor is faulty and if not then the control board is faulty.
