Quick Answer
If your dishwasher won’t start, the most common causes are a faulty door latch, no power to the unit, or a control board that needs a reset. Checking the door, breaker, and performing a simple power reset often solves the problem.
Why This Happens
Dishwashers are designed with safety systems that prevent them from running if something isn’t right. If the door isn’t fully latched, the control board won’t allow the cycle to start. Power interruptions, tripped breakers, or control board glitches can also leave the dishwasher unresponsive.
Startup issues like this are some of the most searched problems in the
Dishwasher Troubleshooting category.
What NOT to Do
Do not slam the dishwasher door repeatedly or try to bypass the door latch. Avoid pressing buttons aggressively or attempting to force the unit to start. Never open electrical panels without unplugging the dishwasher first.
Step-by-Step Fix
- Make sure the dishwasher door is fully closed and latched.
- Check the circuit breaker and reset it if tripped.
- Inspect nearby GFCI outlets and press the reset button.
- Unplug the dishwasher or turn off power for 5 minutes.
- Restore power and select a new wash cycle.
- Listen for water filling or motor activity.
Alternative Fixes
If the dishwasher still won’t start, the door latch switch may be faulty or the control board may be damaged. In some cases, a failed touchpad or timer prevents the cycle from initiating.

Prevention Tips
Close the dishwasher door gently and avoid overloading racks that strain the latch. Use surge protection to protect the control board. Regular inspections described in the
Dishwasher Troubleshooting category can prevent startup failures.
