Common Causes of a Whirlpool Dishwasher Starting and Stopping

Several factors can cause a dishwasher to start its cycle only to halt unexpectedly. Below are some of the most common reasons:

1. Power Supply Issues

One of the first things to check when your Whirlpool dishwasher starts and stops is the power supply. Dishwashers require a consistent electrical connection to run properly. A loose or faulty power cable can interrupt the cycle, causing it to stop suddenly.

2. Door Latch Problems

If the dishwasher door isn't properly latched, the machine may not start or may stop midway through a cycle. The door latch ensures that the dishwasher remains closed during operation. If it is damaged or not fully engaged, the machine may pause, thinking that the door has been opened.

3. Faulty Motor

The motor is responsible for circulating water throughout the dishwasher. If the motor fails, the machine may start the cycle but then halt when it cannot move the water properly. Over time, motors can wear out or burn out, leading to intermittent operation.

4. Control Board Failure

The control board acts as the brain of your Whirlpool dishwasher, governing all operations from start to finish. A malfunction in the control board can cause the dishwasher to stop suddenly or fail to complete the washing cycle.

5. Overheating

Many modern dishwashers, including Whirlpool models, have safety mechanisms that shut off the machine if it begins to overheat. Overheating can be triggered by various factors, such as a clogged filter or faulty thermostat. If the machine shuts off due to overheating, it may require cooling down before it can be restarted.

6. Water Supply Problems

Dishwashers need a steady flow of water to operate correctly. If there's a problem with the water inlet valve or the home's water supply, the dishwasher might stop partway through the cycle due to insufficient water. Clogged filters or kinks in the water supply hose can also impede water flow.

How to Troubleshoot a Whirlpool Dishwasher That Starts and Stops

Before you call a repair technician, there are several steps you can take to troubleshoot the issue on your own. The following checklist can help identify the problem and potentially save you from costly repairs.

1. Check the Power Connection

Ensure that the dishwasher is properly plugged into the power outlet and that the circuit breaker hasn't tripped. If the power cord or outlet is damaged, you may need to replace them. You can also try resetting the dishwasher by unplugging it for a few minutes and then plugging it back in.

2. Inspect the Door Latch

Open and close the door to ensure that it latches securely. If the latch appears loose or damaged, it may need to be replaced. Be sure to check for any debris that might be preventing the door from fully closing.

3. Test the Motor

If you suspect the motor is faulty, you can listen for unusual sounds when the dishwasher starts. A humming noise could indicate that the motor is struggling. In this case, it’s best to call a professional technician to assess and potentially replace the motor.

4. Reset the Control Board

Some Whirlpool dishwashers have a reset function that can clear temporary glitches in the control board. Refer to your user manual for specific instructions on how to reset your model. If resetting doesn’t resolve the issue, the control board may need to be repaired or replaced.

5. Clean Filters and Check the Water Supply

Regularly clean the dishwasher’s filters to prevent clogs that can disrupt water flow. Additionally, ensure that the water supply hose is free from kinks and that the water inlet valve is working properly. If you notice that the machine is struggling to fill with water, this may be the root cause of the problem.

When to Call a Professional

While some troubleshooting steps can be done at home, certain issues may require the expertise of a qualified technician. If you’ve followed the steps above and the problem persists, it may be time to call in professional help.
