How to Reset a Kenmore Dishwasher Diagnostic Cycle

Many Kenmore dishwasher models feature an electronic diagnostic cycle. This feature is designed to automate Kenmore dishwasher troubleshooting, searching for -- and correcting -- minor problems as they arise. However, in some instances the diagnostic cycle itself can malfunction, and your dishwasher runs an endless diagnostic check. If all the dishwasher's LED lights are illuminated and the cycle does not end, you need to reset the diagnostic cycle mode on your Kenmore dishwasher.

To reset the cycle, you may need to shut off all power to your kitchen.

Step 1

Press and hold the "Start/Resume" button on your Kenmore dishwasher. This button controls the power for the entire unit. Holding down the button forces a reset of the system.

Step 2

Shut off power to your kitchen using your home's fuse-box, if the power button does not reset the diagnostic cycle. In some cases, a malfunctioning diagnostic cycle can prevent a proper shutdown, and you must cut off power to the entire unit. Shutting off power at the circuit breaker is much easier than unplugging common units, since most Kenmore dishwashers are designed to be built into cabinetry. If your dishwasher is not built-in, you can unplug it from the wall, rather than turning off the circuit breaker.

Step 3

Flip the circuit breaker switch back on, restoring power to the dishwasher.

Step 4

Press the button again to start up the unit. Whether you reset the system by pressing the button or cutting off the power, you'll need to press the "Start/Resume" button to power the unit back on afterward. Diagnostics will run again, but after a forcible reset, the diagnostic cycle usually proceeds without incident.
