When your dishwasher won’t start a cycle, a defective electronic control board could be causing the problem. The control board will freeze up and fail to start a cycle when its internal memory and logic is corrupted. A failed internal electronic relay or bad electronic part on the circuit board could be causing the control board to freeze up and not start a cycle. Determining whether a control board is defective is difficult. Have a Sears Home Services technician diagnose and repair your dishwasher when it won’t start a cycle.
A damaged power supply board could be causing the problem when your dishwasher won’t start a cycle. The power supply board provides the electrical current needed to operate components such as the fill valve and pumps in the dishwasher. A damaged power supply board won’t provide power to components to operate the dishwasher. When your dishwasher won’t start a cycle, have a Sears Home Services Technician check the power supply board and replace it if it’s damaged.
When the dishwasher won’t start a cycle, a failed door switch may not be detecting that the dishwasher door is shut. Microswitches in the door switch assembly can break or short out. If the control doesn’t detect that the dishwasher door is closed, the dishwasher will not fill with water and start washing. Because the door switch is hard to access and test, have a Sears Home Services Professional visit your home and repair your dishwasher when you suspect that the door switch failed.
First, follow the tips in the owner’s manual for your dishwasher to find out why it won’t run a cycle.
If those basic troubleshooting tips don’t help, check for an item stuck underneath the mushroom float for the overfill switch. The dishwasher won’t start filling if that float is stuck in the up position.
Remove an item it you find it stuck underneath there.
Here’s a DIY troubleshooting video that provides additional expert tips on finding out why your dishwasher won’t start a cycle:
Following the steps in this diagnostic video may help you find and fix the cause of your dishwasher not starting the cycle.
A faulty door switch will keep the dishwasher from starting. If the door switch is stuck in the "open" position, the dishwasher won't start because it's waiting for you to shut the door—even if you did shut the door.
To test the door switch, check the resistance through the door switch with a multimeter. Disconnect electrical power to the dishwasher by shutting off the house circuit breaker or unplugging the dishwasher. Remove the Torx screws from the outer edges of the inner door panel. Support the outer door panel with one hand as you remove the final screws so it doesn't fall.
Separate the outer door panel and the control panel slightly from the inner door panel, and rest the outer panel on the floor while you disconnect the user interface control wire harness. Pull off the outer door panel and control panel.
Release the door latch assembly from the inner door panel and unplug the wire harness from the door switch. Carefully trip the door switch by pushing this lever, keeping your fingers away from the spring and latch. Press the door switch lever to simulate a closed door that's engaging the door switch.
With the multimeter set to check resistance, place a meter probe against each of the door switch prongs. You should measure near 0 ohms of resistance, or continuity, through a working door switch. If you measure infinite resistance, replace the door switch because it's defective.
If you measure continuity through the dishwasher door switch, it’s likely that a defective control board or a wiring failure elsewhere in the dishwasher is keeping the dishwasher from starting.
Schedule dishwasher repair service to have a Sears Home Services technician examine and repair your dishwasher.
Correcting most won't start a cycle problems usually involves replacing the electronic control board, power supply board or door switch. However, there are many potential causes, so a thorough diagnosis is key to fixing the problem. An accurate diagnosis is essential to understanding how much the repair will be.
When the dishwasher won't start a cycle it can be for many reasons. To avoid replacing unneeded parts we recommend having a Sears Home Services professional perform diagnostic tests to identify the root cause of the problem. Our technicians are experienced at diagnosing all types of dishwasher failures.
Diagnosing modern appliances without proper knowledge and training can be difficult. Without using proper diagnostic techniques, fixing your dishwasher problem will only be achieved through changing parts on a hunch. Appliances, especially in the last 10 years, have become extremely advanced, and many models have electronic parts that are difficult to test. DIY repairs on the latest appliance models are becoming increasingly difficult.
When your Kenmore dishwasher ignores the start command, a door latch error or shorted control board might be stopping it. Dishes won’t clean themselves, so consider dishwasher fix near me. A quick repair launches cycles properly.

Thorough
James called to give an estimated arrival time. He was professional and personable. He had 2 professional ideas of the problem and found 1 was correct, but he didn't stop there. He did a thorough check of the appliance. 1 small part was needed. He ordered the part to my house. Fortunately, he was able to schedule for the next week, just before Thanksgiving. As before, he called ahead, arrived and quickly fixed the problem. My appliance is working perfectly.
