Why won't my dishwasher start?

The most common reasons are a door that is not fully latched, the control lock or delay start turned on, a tripped breaker or GFCI outlet, or a wall switch that is off. If those check out, a failed door switch, thermal fuse or control board is likely.

Turn off power at the breaker before you remove any panel. Dishwashers use water and electricity together, so do not open the control panel with the power on.

What are the 7 things to check?

1. Is the door latched?

The dishwasher will not run unless the door clicks shut. A rack or tall pan can stop it from closing all the way.

2. Is the control lock on?

Many models have a child or control lock. When it is on, the buttons do nothing. Look for a lock icon and hold the lock button for a few seconds.

3. Is a delay start set?

A delay timer makes the dishwasher wait hours before it runs. Cancel it and try again.

4. Does it have power?

Check the breaker, the GFCI outlet under the sink and the wall switch some kitchens use for the dishwasher.

5. Will a reset help?

Turn off the breaker for a few minutes, then turn it back on. This clears many control glitches after a power blip.

6. Is there an error code?

Write down any code or blinking pattern. It helps a technician bring the right part.

7. Is a part worn out?

A failed door latch switch, a blown thermal fuse or a bad touch pad can all stop the start. These need a technician to test and replace.

How can you keep it from happening again?

  • Close the door gently; slamming wears out the latch.
  • Load racks so nothing blocks the door.
  • Clean the filter monthly. In parts of Mountain View with harder water, mineral buildup makes parts work harder.
  • Wipe the control panel dry after cleaning.

When should you call a technician?

Call if the dishwasher still won't start after the checks above, if it hums but no water comes in, if it trips the breaker, or if the same error code returns. Most dishwasher repairs in Mountain View run about $150 to $400 with parts and labor.

If your dishwasher runs but leaves water behind, read dishwasher not draining. If it leaks, see dishwasher leaking. For spots and film, read hard water and your dishwasher. See all our dishwasher repair services.
