Diagnostic and troubleshooting steps

Kenmore dishwasher won’t start a cycle? Follow the steps below to troubleshoot common issues like a defective door switch, control board failure, or electrical power problem.

Step 1:

Check the Power Supply

Ensure that the dishwasher is properly plugged into the outlet.
Check the circuit breaker and reset it if necessary.
Inspect the power cord for damage, and make sure the outlet is working by testing it with another device.

Step 2:

Inspect the Door Latch and Switch

Close the door and listen for a clicking sound when it latches.
If you don’t hear it, the door latch or switch may need to be replaced. You can do this by removing the panel and replacing the switch.

Step 3:

Reset the Dishwasher

Sometimes, simply resetting the dishwasher can resolve the issue.
Unplug the dishwasher for a few minutes, then plug it back in and try starting the cycle again.

Step 4:

Clean the Filter

Check and clean the dishwasher’s filter.
Remove any food particles or debris, and ensure that it’s properly seated in place.

Step 5:

Inspect the Control Board

While testing the control board requires specialized tools, you can visually inspect it for signs of damage, like burn marks or cracked components.
If you suspect the control board is faulty, it’s best to call a professional.

Key actions for homeowners:

Regularly clean the filter to prevent clogs and ensure your dishwasher functions efficiently.
Check the door latch periodically to ensure it’s closing properly.
Inspect the water line for leaks or blockages, and clean the inlet valve when necessary.

Most common repairs needed to fix a kenmore dishwasher

When your dishwasher won’t start a cycle, certain repairs are more commonly required than others. Below are the most frequent fixes:

Inspect and Replace Faulty Door Latch or Door Switch: If there’s no continuity or the switch is visibly damaged, replacing the part is essential. This is a relatively simple DIY repair that typically requires a screwdriver to remove the inner door panel. Once the faulty latch or switch is removed, install a new, compatible part designed for your Kenmore dishwasher model. Be sure to reconnect the door switch wiring carefully to avoid any electrical issues.
Check the Door Seal and Gasket: If the seal appears compromised, it’s important to replace it to avoid leaks and ensure the dishwasher runs efficiently. Replacing the door seal is an easy repair that typically requires no tools—simply remove the old seal and press the new one into place.

Frequently Asked Questions

Why won’t my Kenmore dishwasher start its cycle?
There are several reasons your Kenmore dishwasher may not start. The most common causes include a faulty door latch or door switch, power supply issues, a broken control board, or a malfunctioning start/reset button. Check the power connections, inspect the door latch to ensure it's engaging properly, and ensure the dishwasher is correctly set to start. If these don’t resolve the issue, a more complex component like the control board or thermal fuse may need to be replaced.
How can I tell if the door latch or switch is causing the problem?
To check if the door latch or switch is at fault, listen for a “click” when you close the dishwasher door. If you don't hear it, the latch may not be engaging properly, which can prevent the dishwasher from starting. You can also test the door switch for continuity with a multimeter. If there's no continuity or the switch looks damaged, it will need to be replaced.
What should I do if the dishwasher’s power is fine, but it still won’t start?
If your dishwasher is properly plugged in and the circuit breaker is not tripped, but it still won’t start, the issue could lie with the control board or the start/reset button. The control board manages all of the dishwasher's functions, and if it's malfunctioning, it could prevent the cycle from starting. In this case, you’ll likely need to replace the control board. The start/reset button can also wear out over time, so make sure it’s working properly before considering more complex repairs.
Can I fix my Kenmore dishwasher myself, or should I call a professional?
Many issues with a Kenmore dishwasher won’t start a cycle can be resolved with DIY repairs, such as inspecting and replacing the door latch, cleaning the filter, or resetting the circuit breaker. However, if the problem involves more complex components like the control board or thermal fuse, it's advisable to call a professional technician. Working with electrical components or diagnosing deep mechanical issues can be tricky and might require specialized tools and expertise.
