Dishwashers are modern conveniences that many homeowners come to depend on. When you load yours and turn it on but nothing happens, it’s natural to worry. Before you panic, though, you should know that there are a handful of simple things to check that might solve your problem. Otherwise, you can count on the experts at Detroit Appliance to diagnose and repair any electrical or mechanical issues. Here are some common reasons for a dishwasher not starting.
Check the Power Supply First
A power failure is one of the most common reasons a dishwasher can fail to start, so it’s the first thing to check. If your dishwasher has an illuminated display, check whether it responds. If other nearby appliances have also stopped working, a power failure is the likely culprit. You can also check the circuit breaker for the circuit that powers your dishwasher. If needed, reset it and see if that resolves the problem. If your dishwasher has power but won’t start, check the following causes.
Make Sure the Door Is Closing and Latching
Dishwashers all have door and latch sensors that ensure their doors are fully closed before beginning a cycle. If your dishwasher door hasn’t closed all the way, the dishwasher won’t start. Check for anything blocking the door from closing fully. Be sure to also check your dishwasher’s door latch. If it doesn’t engage fully, it may prevent operation. Worn or damaged door latches can prevent your dishwasher from starting, even when the door is fully closed.
Check the Control Settings
Some dishwashers have settings that can make them refuse to start as expected. If your dishwasher has a delayed start mode, check whether you’ve inadvertently activated it. Next, check whether a control lock setting is preventing proper cycle selection. If neither applies, review your cycle selection. If your dishwasher didn’t complete a previous cycle, you may need to cancel or reset it manually. Otherwise, check your current cycle selection, and make sure your dishwasher isn’t waiting for further input.
A Faulty Door Switch May Prevent Startup
If your door switch is the cause of your problem, you may find that moving it around slightly will cause your dishwasher to activate. In that case, you likely need a new door switch. Door latch sensors or tension springs can also fail, preventing your dishwasher from starting. In either case, one of our appliance experts will diagnose the problem and replace the latch.
Electrical Problems Can Keep the Dishwasher From Running
There are a handful of internal electrical components that may fail in ways that prevent a dishwasher from starting. Control boards, wiring, fuses, and power supplies are common culprits. Often, internal electrical issues will produce additional symptoms. For example, a circuit breaker that frequently trips warrants calling a professional for repair. Watch out for burning smells in or around your dishwasher or sudden power losses as well.
The Control Panel or Electronic Controls May Be Failing
The control knobs or panels of the average dishwasher may also fail in ways that prevent proper operation. If you notice visible wear on your dishwasher controls, they may need replacing. If your dishwasher’s touch controls often freeze or seem unresponsive, have them checked. Sometimes, intermittent responses from certain buttons can indicate failing control circuitry. If your dishwasher lights are on but it won’t start, failed circuitry could also be to blame.
Water Supply Problems Can Interrupt the Cycle
You should also be aware that issues with your dishwasher’s water supply or drain can prevent proper operation. For example, a clogged drain is a common reason for a dishwasher not turning on. This self-protection mechanism prevents leaks or pump damage. A faulty water supply valve or inlet valve may also prevent your dishwasher from starting.
When Should You Schedule Dishwasher Repair?
With so many common causes of dishwasher issues, it’s not always easy to know when to schedule dishwasher repair. If your dishwasher start button is not working and resetting the controls doesn’t help, call for repairs. If your dishwasher has power but won’t start, you should call for a repair appointment. The same applies if your dishwasher door won’t latch properly. Unresponsive controls or a dishwasher that starts but immediately stops also warrant a repair call.
Some situations suggest you should stop using your dishwasher immediately and call for a professional repair. They include a repeatedly tripping circuit breaker, crackling sounds near your dishwasher, and burning smells. Those symptoms often indicate serious electrical malfunctions that require urgent attention.
Repair or Replace the Dishwasher?
When your dishwasher needs repair, you may wonder if replacing it is a smarter investment. Generally, that decision hinges on your dishwasher’s age, overall condition, repair history, and the cost of the needed repair. Our experts can help you decide what’s best after diagnosing your dishwasher’s specific problem.
