Dishwasher Won't Start? Door Latch, Control, or Power.

When a dishwasher won't start, it's almost always one of three things: the door isn't latched (or the latch is broken), the control board has failed, or there's a power issue at the unit.

Common causes

What's actually wrong

Door latch / switch

Most common. Dishwashers won't start unless the door latch electronically signals 'closed.'

Control board failure

Touchpad or main board failure on built-in models. Common at year 7-10.

Thermal fuse on control board

On some models, a small thermal fuse on the board pops and disables the unit.

Power supply at the unit

Sometimes the obvious — a tripped breaker or a loose connection at the junction box.

Bosch tension cord broken

On Bosch built-ins, broken cords cause the door not to seat — and the unit won't run.

Before you call

Quick checks you can do

  • Check the breaker.
  • Open and close the door firmly. Listen for the latch click.
  • Try a 'reset' by holding the cancel/drain button (varies by model).
When to call us

Latches and control boards are common replacements. We diagnose with a multimeter — no guessing on parts.
