A malfunctioning dishwasher can disrupt your daily routine and leave you with a pile of dirty dishes. At Pro Service Mechanical, we often receive calls about dishwasher problems. This guide will help you troubleshoot common issues and understand when it’s time to call a professional.

Common Reasons Why Your Dishwasher Stopped Working

Power Supply Issues

Sometimes, the problem isn’t with the dishwasher itself, but with its power supply. A tripped circuit breaker or blown fuse can prevent your dishwasher from turning on.

Door Latch Problems

If the door latch is faulty or misaligned, your dishwasher won’t start as a safety precaution.

Clogged Filters

Over time, food particles can accumulate in the dishwasher’s filters, affecting its performance or preventing it from starting.

Water Supply Problems

If your dishwasher isn’t getting water, it won’t be able to run a cycle. This could be due to a closed water supply valve or a kinked supply line.

Less Obvious Causes

Faulty Float Switch

The float switch prevents overfilling. If it’s stuck or faulty, it might signal that the dishwasher is full when it’s not, preventing it from starting.

Thermostat Issues

If the thermostat is malfunctioning, it might not signal the heating element to activate, which can prevent the cycle from starting or completing.

Pump or Motor Failure

More serious issues like a failed pump or motor will require professional diagnosis and repair.

Control Board Problems

The control board is the brain of your dishwasher. If it’s malfunctioning, it can cause various issues, including failure to start.

DIY Troubleshooting Steps

Check the Power Supply

Ensure the dishwasher is properly plugged in and the circuit breaker hasn’t tripped. Reset the breaker if necessary.

Inspect the Door Latch

Make sure the door is properly closed and latched. Clean any debris that might be preventing the door from closing fully.

Clean the Filters

Locate and remove the dishwasher filters. Clean them thoroughly with warm, soapy water and rinse well before replacing.

Verify Water Supply

Check that the water supply valve under the sink is fully open. Inspect the supply line for any kinks or damage.

Run a Reset Cycle

Many dishwashers have a reset function. Consult your owner’s manual for instructions on how to perform a reset cycle.

Check for Error Codes

Modern dishwashers often display error codes when there’s a problem. Refer to your manual to interpret these codes and follow recommended actions.

When to Call a Professional

Electrical Issues

If you’ve checked the power supply and breaker, but your dishwasher still won’t turn on, it’s time for professional help.

Water Leaks

Any signs of water leaking from your dishwasher warrant immediate professional attention to prevent water damage.

Unusual Noises

Strange sounds like grinding, buzzing, or clicking during operation could indicate mechanical problems that need expert diagnosis.

Incomplete Cycles

If your dishwasher starts but doesn’t complete cycles, or if dishes aren’t getting clean, a professional can identify the underlying issue.

Age of the Dishwasher

If your dishwasher is over 10 years old and having frequent issues, it might be more cost-effective to replace it rather than continue repairs.
