Jillian for Model Number KUDD01DPPA1

I have 2 Kitchen-Aid dishwasher drawers. Problem is the same with both of them. After selecting cycle dishwasher fills with water and begins cycle only to stop mid-cycle - and regardless of cycle chosen appears to be stuck, blinking "Heavy/Rinse" litghts and they stop working. I have replaced the rotors in both, dried out the overflow pan underneath but the problem persists. So far it has cost me around $700 and no solution. Latest repair service thought there might be a slight puncture in the top drawer pan and suggested it should be replaced! More cost which as this stage would not be worth it. The control board appears to be sealed in the plastic tub - could this be the problem and if so how does one replace it? Does it mean completely disassembling the dishwashers? Any and all ideas/solutions would be welcomed. Thanks!

Hi. Code: Fill failure. Water supply valve turned off. Make sure the valve is cycled on and off a few times to remove any clogs or sediments. Inlet valve part # WP8194068 failed. Check resistance of the solenoid coils, 65-75 ohms per coil. Replace if open or more then 10% out of tolerance. Low water pressure. Incoming water pressure must be above 4.3psi. If the water inlet valve is good then make sure the inlet screen is not clogged. Spray arm not in place. Replace the wash arm in its proper location. Obstructed inlet supply water hose or kinked. Bad wiring to the junction box or the controller. Machine is siphoning. Check drain hose installation so there are no vapor locks creating siphoning. This is the tech sheet for the model. Control board part # WP8564543. Thank You.

My dishwasher (Kitchenaid model # KUDP01DLBT0) does not drain completely at the end of a wash cycle. I have to push the cancel button to get it to drain. We already cleaned all the drain hoses, so there isn't a blockage of any kind. When I press the cancel button, the dishwasher displays "2" for the "2 minute" drain cycle, and the dishwasher drains for the full 2 minutes whether it needs to or not. It makes a horrible rackety sound while it is still trying to drain when there isn't any liquid left to drain. The dishwasher is 8 years old. Could this be a problem with the electronic control panel? If not the control panel, what could be causing this problem? Thanks!

Margo, You're going to need to remove and check the drain pump WP661658 and housing for debris, that could be causing the noise and the poor drain performance. Drain pump noise level will incease once the water is drained, but the "horrible rackety sound" is indicative of a problem. " Removing the Drain Pump Motor 1. With one hand, press back on the plastic tab that holds the pump motor from rotating. 2. With the other hand, rotate the pump motor counterclockwise approximately ¼ turn. The pump motor will now be free of the pump assembly."

Hello Tom,

The complaint you describe is most likely going to be a stuck button on the control panel WP8270232. When a button is stuck, the light above the stuck button will flash, as described on the tech sheet.

Hello KD,

While you may not have hurt the ribbon cable, hard to say for sure, it is not recommended to clean the ribbon cable with any solvent. The recommended method of cleaning it is by rubbing it only in the direction of the traces toward the end of the cable with a regular pencil eraser. This will leave no residue like alcohol will and as long as the eraser rubs the ribbon along with the traces, will not separate the traces from the ribbon.

The complaint you describe is most likely going to be a stuck button on the control panel WP8270224. When a button is stuck, the light above the stuck button will flash, as described on the tech sheet.

Hello Brian. If there is a button stuck on the control panel, you will need to order and replace the control panel WP8531257 on the unit.

Hello Christopher,

The components on this unit are 120Vac. Nothing that I see on the wiring diagram is dc voltage. The control board WP8564543 is bad on this unit.

Ivy, Don't replace anything, yet. Your dishwasher maybe operating properly. There are sensors in the pump, if the sensors inform the control to heat the water or there is a large amount of soil on the dishes, etc. the control extends the cycle, and the displayed time can increase or decrease. We'll send you some information that will be helpful in explaining the operation and things you can check.

Hello Boni. Based on the information you provided, it sounds like the control panel WP8270228 may be bad in the unit. Try removing the ribbon cable and cleaning it. If the issue continues, replace the control panel.

Lotus for Model Number KUDM01TJBT0

So are you suggesting that I need to replace both Control Panel and Control Board? First I replaced Control Board but it didn't work so you suggested to replace control panel.So returned the control board and I replaced the control panel which worked 2-3 weeks and then stopped working. Your sales rep sent another control panel but that is also not working. Is there anything else that might be wrong ie fuse? ============================== This is regarding latest question in this thread. I actually replaced control panel twice (not control board). I think confusion arose because I posted question in control board page. I reposed question to control panel page. Any suggestions? Asked by Lotus for Model KUDM01TJBT0 Hello Lotus. If the control panel is new, then you will need to replace the control board AP3775506 on the unit if it is not working.

Hello Lotus. If the lights, work, but none of the buttons work, it is not the fuse. If the whole thing is dead, no light nothing, then the fuse 8193762 could be the issue with the unit. Based on your past questions, it sounded like the lights worked, but no buttons worked. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
