Dishwasher Won't Start: Causes and Fixes
A dishwasher that won't start usually has a door that isn't latched, an active Control Lock or Delay Start, or a power issue at the breaker. The door latch must fully engage for the cycle to begin. Confirm the latch, check for lock/delay modes, then reset power.
What to Check First
- 1
Push the door until the latch clicks firmly — a misaligned or worn latch is the #1 no-start cause.
- 2
Check for Control Lock (often a 3-second button hold) and cancel any Delay Start.
- 3
Confirm power at the breaker — dishwashers are usually hardwired or on a dedicated circuit.
- 4
Make sure a cycle is actually selected and Start was pressed and the door closed within the start window.
- 5
Power-cycle at the breaker for 60 seconds to clear soft faults.
