When a dishwasher gives you nothing at all — no lights, no hum, no response to the start button — the cause could be as minor as a setting or as significant as a failed control board. Working through these steps in order rules out the easy answers first.
Step 1: Confirm the Door Is Fully Latched
A dishwasher won’t run at all if its door latch isn’t detected as fully closed. Push firmly until you hear or feel it seat, and check for any food debris along the latch mechanism itself.
Step 2: Check for a Delayed Start Setting
It’s a surprisingly common false alarm: a delay-start option left active from a previous use can make a dishwasher appear dead when it’s actually just waiting for its scheduled time.
Step 3: Check Power at the Source
Confirm the dishwasher’s dedicated breaker hasn’t tripped, and that any under-sink shutoff switch for the unit is in the on position.
Step 4: Look for a Locked Control Panel
Many models include a control lock feature to prevent accidental changes, often engaged by holding a specific button for a few seconds. An accidentally locked panel looks identical to a dead unit at a glance.
