Dishwasher Not Turning On? What to Check First

Let the panel guide your first check

When button presses get no response, we'd check the external power supply first because an unlit, unresponsive panel can mean power isn't reaching the dishwasher. When the controls respond, we'd move to the door and settings because those can hold up a machine that has power.

The possibilities worth checking before a service call include a disconnected supply, an incompletely latched door, control lock, sleep mode and delayed starting. Water supply belongs in that first round, too. Use what you can see to choose your next check, then follow the instructions for your brand and model.

Keep one exception in mind if you own a GE dishwasher. Some GE models have Sleep or Sabbath Mode, which switches off lights and sounds while power remains connected; use your model's owner's manual to turn that feature off. GE's US no-start guidance (opens in a new tab) explains this exception.

A plug or switch may be interrupting power

If your dishwasher has a plug, make sure it's plugged in. Whirlpool's power checks cover both plug-in and hardwired installations, so a machine without a power cord sends you to the circuit breaker check below.

For a GE dishwasher fitted with a cord, look in an adjacent cabinet or the cabinet under the sink for its outlet. A loose cord can interrupt the supply, and the outlet needs to be functioning. Those locations are part of GE's US power guidance (opens in a new tab), with the cord check applying only when one is fitted.

If that GE dishwasher is plugged into a GFI/GFCI outlet with a Reset button, press Reset to restore power. If its installation uses a wall switch, make sure the switch is on. GE suggests looking around the kitchen counter or under the sink for a switch you don't normally use.

For a Bosch dishwasher, you can check the outlet by plugging in another device. If that device doesn't work either, the problem may be with the outlet or your home's electrical system. Bosch's US troubleshooting guidance (opens in a new tab) uses that result to separate an outlet problem from the appliance checks.

Check the dishwasher's circuit breaker

Locate your home's electrical panel and identify the breaker connected to the dishwasher. A tripped breaker is a possible reason the machine has lost power, including on a hardwired Whirlpool dishwasher.

For the breaker check, Whirlpool's instructions (opens in a new tab) say to move that breaker to Off for a few seconds, then back to On. Check whether the dishwasher responds afterward. This is the breaker action for the supply check; the Whirlpool control reset later includes Cancel and a longer power interruption.

Bosch also directs owners to check the electrical panel for tripped circuit breakers or blown fuses that could affect dishwasher operation. Keep this check at the external controls. Leave wiring, fuse replacement and panel removal to professional help.

The door needs to latch, not just look closed

Make sure the door latches completely before trying to start a cycle. It can look closed while still being unlatched, so pay attention to whether it actually closes securely. On a Whirlpool dishwasher, a lower rack installed backward can prevent the door from latching.

On a GE dishwasher, open the door and close it firmly after checking for an obstruction. A rack that's not pushed fully in or a pan handle can block closure. Trim, insulation, cabinetry or the countertop can also interfere with the door; the latch must fully engage so the switch can signal that the dishwasher is ready to operate.

Bosch identifies full door closure as a safety requirement: its dishwasher won't start with the door improperly closed. Its display guidance also includes the latch check when the screen won't light up, so a dark Bosch panel still deserves a door check after the supply checks.

Whirlpool worked example for locked or sleeping controls

Look for an illuminated lock icon on your Whirlpool dishwasher's display. Control lock prevents unintended use and disables the buttons, so pressing Start while it's active won't begin a wash. Some models also have a sleep mode.

The lock light can stay on briefly to show that locking is active. Whirlpool's support guidance describes that light flashing three times when you press a button with the controls locked. Use that specific indication to check control lock, then follow your owner's manual for the unlock method.

Whirlpool's reset blog (opens in a new tab) gives a method of holding the lock button for three seconds and notes that flashing behavior depends on the model. Its US support guidance (opens in a new tab) instead directs you to your model's owner's manual. We'd follow your model's directions because the applicable controls and indicators vary.

If your Whirlpool has sleep mode, wake it by opening and closing the door, or by pressing Start/Resume or Cancel. Check the panel's response after waking it. For a GE or Bosch dishwasher with locked controls, use that model's owner's manual for the unlock instructions.

Whirlpool delay settings can leave it waiting

Check for a delay indicator or a countdown on your Whirlpool dishwasher. A delay wash schedules the cycle for later, so the machine waits until the selected time arrives. That waiting period can explain why it accepts settings but doesn't begin washing.

To cancel a delayed cycle, Whirlpool's US support guidance (opens in a new tab) specifies CANCEL/DRAIN. Use that named control when following the support-page method.

Whirlpool's blog gives a different method (opens in a new tab): select the Delay button again once the displayed time is counting down. With that method, the dishwasher should start immediately and the delay indicator should switch off. Keep these as separate methods and use your model's instructions to choose the applicable controls.

If you're trying to keep a delayed start instead, the blog describes pressing Start/Resume within 30 seconds of selecting delay to begin the countdown. Otherwise, the dishwasher may turn off. This timing belongs to that delay-setting procedure.

Whirlpool also needs its water supply on

Confirm that your Whirlpool dishwasher's water supply is turned on. If it doesn't detect water, the cycle won't start, so this check still matters when the controls respond.

If you're unsure how to check the supply, use the installation instructions for your model. Whirlpool's water-supply guidance (opens in a new tab) makes that the next step for an uncertain owner. Keep this to confirming the supply is on before moving to the control reset.

Try the Whirlpool control reset

Try this after the external supply, door and settings checks. Whirlpool's US control-reset procedure (opens in a new tab) may help restore operation by reinitializing the controls. Cancel clears the current settings and halts any current cycle, so expect to choose your wash settings again.

1. Press Cancel to halt any current cycle and clear its settings. Check the panel's response.
2. Unplug the dishwasher, or switch its circuit breaker off, and leave power disconnected for about one minute. Keep the plug disconnected or the breaker visibly at Off during that interval.
3. Reconnect the plug or switch the breaker back on to reinitialize the controls. Try starting a wash and check whether operation returns.

For another brand, follow its own reset instructions. Reset methods vary by brand and dishwasher type: some use power removal, while others use a Start/Reset control. The Whirlpool sequence above is a family-level worked example, with your model's instructions governing its controls and features.

When to book a technician

If checking the settings, water supply and door, followed by the reset, still leaves the dishwasher unable to run, book an appliance technician. Describe whether the panel stays dark, responds to buttons or shows the lock indication, and explain which checks you've completed.

Leave internal diagnosis to that appointment. Whirlpool names a faulty drive motor or failing electrical components as possible problems a professional can assess, including whether repair or replacement makes sense. Keep the appliance in place and leave disassembly and electrical testing to the technician.

For a newly installed GE dishwasher with no power, contact the company that installed it. GE says installation issues aren't covered by the dishwasher warranty. For unresolved GE no-start problems, GE's US support page directs owners to Bodewell (opens in a new tab) for a repair appointment.

For a Bosch dishwasher that still won't start, contact Bosch Support at 1-800-944-2904 for assistance or to book service. You can also use Bosch's US troubleshooting and service guidance (opens in a new tab) to find a Bosch authorized servicer.
