Try resetting the dishwasher. If the dishwasher won't start but has power, it could be stuck between cycles. If the start button has been pushed more than once, the dishwasher may revert to a drain cycle. To remedy this, allow the drain cycle to run, let it sit for 60 to 90 seconds, then press the start button once.
The most common reasons a dishwasher will fill but not start the wash cycle are a broken drive motor, faulty wash arms, or a detergent door that's stuck closed. You can either try to diagnose and repair the problem yourself or hire a professional to come check it out.
Several factors can contribute to this, including: Power Issues: The dishwasher might not be plugged in, the circuit breaker could have tripped, or there might be a blown fuse. Door Latch: As mentioned earlier, if the door doesn't latch correctly, the dishwasher won't start as a safety measure.
Some models require you to shut off the power to the dishwasher either by unplugging it or shutting off the circuit breaker. Others are reset by pressing and holding the Start/Reset button on the control panel, then waiting a few moments before attempting to start a wash cycle.
It could be an improperly positioned drain hose, a door that's not fully closed, a water supply that's turned off or an overfill protection float that's got something stuck in it.
Here's a short checklist of ways you can find out why your dishwasher might be turning on, but not getting water. An open or unlatched door, a clogged or malfunctioning water inlet valve, a shut off water supply or an obstructed overfill protection float could be the culprit.
Signs pointing to a faulty inlet valve include: Leaks that fill the dishwasher when it's off. Inadequate water for a cycle. The dishwasher fills too slowly or not all.
Your dishwasher takes a moment to start because it's draining first. If it doesn't start right away, it could be due to Child Lock, Delay Start, the door not being closed all the way, or just holding the Start button for too long.
If you find your dishwasher stopping mid-cycle, it could be due to several reasons, including a malfunctioning door latch, a defective control board, or even a power interruption.
Issues like leaks, poor drainage, unclean dishes, foul odors and overall appliance operation, though infrequent, can be the most common problems with a dishwasher that isn't operating properly. In some cases, you can resolve these issues with a little elbow grease and the help of your product manual.
Most dishwashers have a Start button that doubles as the reset button. You can also reference your dishwasher owner's manual to determine the exact location of the reset feature.

You will want to consult your owners manual to find manufacturer instructions on how to reset a dishwasher that has power but is not turning on.
How do I know if my dishwasher's control board is faulty? Look for symptoms like unresponsive buttons, erratic cycle behavior, frequent error codes, or the dishwasher failing to start or complete cycles. These often indicate control board issues.
Make sure the dishwasher is in Standby mode (no cycle running). Press the "Heated Dry," and "Normal," buttons one after the other, twice. After entering the correct button sequence, the control panel should light up as the dishwasher begins the reset.
It usually costs around $80 to $125 to replace the water inlet valve.
