Paul999 for Model Number KUDP01DLBS3

I replaced the control bd and it worked fine for 3 days. Now there is nothing on the display. I jumpered the door switch, still nothing. The original problem: it stopped mid-wash with 2 dash lines on display and control bd was burnt on pin 8 (tan wire) which come off the switch. I checked the new bd, it's not burnt and the connection to pin 8 is solid as are all the connections. I've not checked the thermofuse but it looks the same. What could be causing this and or blowing the thermofuse if that's the case? Also is the control bd now bad?

Hello Paul999. It sounds like the fuse 8193762 is bad and needs to be replaced. Make sure the wires are replaced with the new fuse. If not, the fuse will continue to blow in the unit. Hope this helps.

Hello Lee. Remove the ribbon cable from the control board and make sure it is clean and dry. Reinstall the ribbon cable and turn the power back on to the dishwasher. See if the unit works properly. If not, you will need to replace the electronic control assembly WP8564543. Hope this helps.

Hello Paul999. The two dashes on the display indicates the door switches WP8269209 are bad on the unit. If the board is burnt, the switches could have shorted it out and the board WP8564543 will need to be replaced as well. Hope this helps.

Hi Katrina. Air Dry: Opens the circuit to the heater element during the dry period of the cycle. This option is not available on quick wash or rinse only cycles (which have no dry period).Stuck Key: If the control detects that a key is stuck in the depressed position, dishwasher operation will be suspended and the control will flash the LED associated with that key until the condition is corrected. If a key without an LED is stuck or multiple keys are stuck, the control will flash the lock-out LED. The keypad is part # WP8269826. Access the tech. sheet in the lower kick plate and enter a field service test to check further. Thank You.

Walter, You most likely have a problem in the keypad/control panel assembly WP8270233, "STUCK KEY: If the control detects that a key is stuck in the depressed position, dishwasher operation will be suspended and the control will flash the light for that key until the condition is corrected. If a key without a light is stuck or multiple keys are stuck, the control will flash the light for the Rinse Only/Quick Rinse key." Pressing the following option keys in the sequence shown will either start the Diagnostics Cycle or turn on the Rapid Advance feature for stepping through customer selectable cycles: HI TEMP SCRUB, AIR DRY, HI TEMP SCRUB, AIR DRY Or SANI RINSE, AIR DRY, SANI RINSE, AIR DRY (Note: HI TEMP SCRUB = HI TEMP SCOUR) (Note: AIR DRY = NO HEAT DRY = ENERGY SAVER DRY)" and here's how to reset the control board " If the above key sequence is entered with the dishwasher in Standby, the Diagnostics Cycle is started. The Diagnostics Cycle can be rapid-advanced, interval by interval, by pressing the Pots&Pans/Heavy or Anti-Bacteria/Cookware or Start key". That's where you need to start. Thanks and Good Luck

Tim K for Model Number KUSD

Model KUDS01FLSS2. User Interface Panel (UIP) lights are not illuminated, washer does not work at all. Previously replaced UIP board because of water corrosion issue and failure. Washer worked for several months until total failure with UIP lights no longer illuminated. Suspected Electronic Control Assembly failure due to water corrosion because it is located immediately below the UIP and it appeared to have same corrosion. Removed and replaced Electronic Control Assembly AP3775964 (8564542). Verified power to fuse on Electronic Control Assembly unit is 120 volts. Unit appears to be fully hot, but User Interface panel lights are still not illuminated. Have not yet performed voltage level troubleshooting on each electrical component. Any suggestions before I begin this process?

Hello Marilyn. Check and make sure the water is coming into the unit hot and that the water level inside the unit is correct and the heater is working. If so, then it sounds like the control WP8564543 could be bad and will need to be replaced. Hope this helps.
