KitchenAid Dishwasher KUDS40CVSS3 stops after 20 minutes

We purchased our home a few months ago and have had issues with our Kitchenaid KUDS40CVSS3 dishwasher since our first use. The first time we used it, the cycle stopped and had no lights, no response to the control panel, nothing. I flipped the circuit breaker, waited a while (probably an hour), reset the breaker, and still nothing.

I ordered and replaced the thermal fuse and everything seemed to be good. I hit the cancel button and the dishwasher drained the water that still remained. I started a new cycle, seemed to be working fine, came back 30 minutes later, and noticed it had stopped with a flashing start/resume button, the normal wash button still lit, and the heat dry button lit.

Thought it odd, but pressed the start/resume button and it started running again. 10 minutes later, it stopped again with no lights, then the same three lights came back on with the flashing start/resume. Pressing the cancel button drains the dishwasher for approximately 2 minutes, then all lights are off. Opening the door at this point reveals plenty of steam, an open soap door, and wet dishes.

Doing the Heat Dry-Normal-Heat Dry-Normal diagnostics reveals nothing. The diagnostics run for approximately 20 minutes, stops, then all lights go off.

The wife is ready to have a functioning dishwasher, so any and all help is appreciated!!!

Hi, it sounds like a bad control panel keypad assembly.

To help you determine which part is bad, Your tech. data sheet says this:

To determine if the control board or keypad is faulty, do the following test:
Unplug dishwasher or disconnect power. Open the dishwasher door. Open console and disconnect the keypad ribbon connection from the control (at P1). Make sure all other connections are made. Put console back together. Do not close the dishwasher door. Plug in dishwasher or reconnect power. Wait 5 seconds. Close dishwasher door. Monitor the control’s response.

➔If the control board is OK (no longer sees shorts with the keypad unplugged), it will respond by turning on the drain motor for 2 minutes. Replace the control panel keypad assembly if the control board responds OK.

➔If the control board is not OK (still sees shorts with the keypad unplugged), then the drain motor will NOT respond. If drain motor does not start within 10 seconds, repeat or verify that all steps were followed, and then replace the control board.

Here's the control panel keypad assembly for your model you can order if the control board is OK:
WPW10084124 Panel-Cntl


Let us know the results.

Thanks Jake. The drain motor kicked right on after closing the door, so we're pointing toward the keypad as the culprit. Anybody getting away with doing component-level changes these days or is it all swaptronics on major assemblies?

You nailed it!

No, no component level changes can be done, just swap the control panel keypad assembly with the new one you order.

Let us know how it goes.
