Todd for Model Number KUDIO1FLSS6

I have a kitchen aid dishwasher and there are no lights on the control panel. I checked with a multi meter and I have 120v to the appliance. Furthermore I checked the thermal fuse and it's correctly reading closed. I also checked the voltage at the thermal fuse and it's 120v. About a week ago I replace the main water pump (old one was leaking). Everything was working well but after running it 3 times with the new pump it quit in the middle of the cycle and there are no lights at the control panel. From reading the posts on the forum and on your site everything seemed to point to the electronic control board (pn 8564543). I ordered that from your site and replaced it but there are still no lights on the control panel. What should I try next?

Hello Todd. The thermal fuse 8193762, even though it is testing good, it most likely failing under a load and will need to be replaced with the new wiring sent with it. It is commong to test good but fail under a load. You can test for power passing through it but be carefula dn do not get shocked.

Bill, Recheck the wire connections at the heater and the hi limit thermostat. Run the diagnostic cycle "HIGH TEMP(Power Scour)>AIR DRY (No Heat Dry)(Energy Saver Dry)>HIGH TEMP(Power Scour)>AIR DRY(No Heat Dry)(Energy Saver Dry) DIAGNOSTICS CYCLE SERVICE FEATURE – Press the above option keys in the sequence shown, while the dishwasher is inactive, to run the Diagnostics Cycle. This cycle may be rapid advanced, interval by interval, by pressing the Pots&Pans/Heavy key, Antibacteria/Cookware key, or Start key." to reset the control board. Start a wash cycle, and check the water temperature in the bottom of the tub when the dishwasher starts to wash, the temperature in the tub needs to be 120 to 130 dgrs.F. for the machine to heat and advance properly.

Forthecos, If you have 120 vac going into the control board but nothing coming out of the control board then the control board is bad and would need to be replaced.

Kip, You will want to check to make sure that the wiring does not have any shorts in it but it sounds like the board failed due to faulty or weak part.

Jeff for Model Number kudp01flbi6

I have a 7 year old Kitchenaid dishwasher. I have replaced the touch panel and interface about 6 months ago with no problems. Now the dishwasher has stopped working. I can push the buttons to start with the corresponding leds lighting up. If I hit start it blinks like it should. However, the unit never starts. The only other issue I have noticed is that before this lately we we would see dirty water left in the unit. I just cleaned the chopper assembly but still won't start. Also did the diagnostic test hitting the four button combination with no luck. What could be the problem?

1 Answer

Jeff, You will want to check to make sure that when you hit start that you are getting power to the water valve. The water valve energizing is the first step in the process. If there is no power to the water valve you will want to check wiring from valve back to control panel board and if wiring checks ok then check to make sure that the connection between the control board and user interface is a firm connection.

Gino for Model Number KUDM01TJWH0

Hi, this is Gino again. My control unit could be bad, but I disconnected the ribbon wires from the board and connected them back. Flashing lights stopped, and my dishwasher is working again! I understand that it can be temporary solution, but if my dishwasher will stop again, I will try to disconnect the wires again. My question is, why the disconnecting wires worked, when unplugging did not? Does it give you any clue what part is faulty? Thanks!

1 Answer

Hello Gino. If the issue happens again, you will need to replace the control panel on the unit. If not, it sounds like you have got it fixed!!

Elaine S for Model Number kitchenaid KUDS01FL dishwasher

The unit is approximately 7 years old. My husband just replaced the door tensioners and latch. It kept falling open & then latch didn't seem to be holding. The unit was working fine again after he fixed it. I have used it for several weeks but now no lights are coming on panel at all. Seems like it quit mid-cycle since there was still water in bottom. My husband has taken it apart. All the connections seem to be fine. Verified power is going to dishwasher & reset breaker but still no lights on panel & is not operating. Do you think it is the control board?

1 Answer

Elaine, You will want to check the thermal fuse for in the control panel area for continuity. If there is no continuity then the fuse is bad and needs to be replaced. If the fuse is good make sure that there is power getting to the control board and check to make sure that the latch is making good contact. With door closed make sure that you have 120 vac at the latch assembly. If power getting to the control board and the latch has power then the control board would most likely be the cause.

Steve, A non responsive light on the display is a general indication that there is a problem with the user interface.
