Faulty Door Latch Switch
If your Kenmore dishwasher won’t start, the issue could be the door latch switches. A dishwasher’s door latch ensures it stays shut during a cycle to prevent water leaks. It also turns on the door switch to supply electric power to your dishwasher when the machine is closed.
- Unplug the dishwasher to inspect the door latch and switches.
- Remove the inner door panel to access the door latch assembly at the top.
- Confirm that the latch activates the switches when you close the dishwasher door.
- If the door latch activates the controls, remove these mechanisms and use a multi-meter to test for continuity.
- If the controls do not have continuity, you may need to replace the door latch assembly.
Defective Timer or Electronic Control
- Access the timer (look behind the cycle control knob), and inside the timer housing you will find several contacts that are controlled by a little motor.
- Use a multi-meter to check the timer contacts for continuity.
Damaged Selector Switch
Faulty Motor Start Relay
Thermal Fuse Issues
- Unscrew the inner door panel and locate the thermal fuse—it comes with two wires.
- Remove these wires and use a multi-meter to check for continuity.
Broken Drive Motor
- Unplug the dishwasher.
- Remove the lower access panel to locate the drive motor.
- Use your multi-meter to check the motor windings for continuity.
