When Your Dishwasher Refuses to Start
A dishwasher that will not start is frustrating, but the cause is usually one of a small number of common issues — many of which do not require a repair visit. Work through these checks before calling.
Check These First
- Door latch: Dishwashers will not start unless the door is fully latched. Press firmly until you hear a click. A worn latch may feel like it is closed when it is not.
- Child lock activated: Many modern dishwashers have a child lock that disables all controls. Check your manual for how to deactivate it — usually holding a specific button for 3 seconds.
- Control lock or delayed start: If someone accidentally activated a delay start, the machine will appear unresponsive. Check the display for a countdown or lock indicator.
- Power supply: Check the circuit breaker for the kitchen circuit. Dishwashers in NYC apartments sometimes share a circuit that trips under heavy load.
If None of That Works
- Faulty door latch switch: Even when the latch clicks, the micro-switch behind it may have failed. The dishwasher thinks the door is open and refuses to start — a common and easily replaceable part.
- Thermal fuse blown: A blown thermal fuse cuts power to the control board completely. This is a safety device that blows if the dishwasher overheats.
- Failed control board: If the display is completely dead and power is confirmed, the control board itself may have failed — particularly common after power events in older NYC buildings.
- Water supply issue: Some dishwashers will not start a cycle if they detect no water pressure at the inlet valve.

Step-by-Step Diagnosis for a Dishwasher That Won't Start
Before calling for service, try these steps: (1) Open and firmly close the door until you hear a definitive click — most dishwashers require the door to fully latch before the control board enables starting. (2) Check the circuit breaker for the dishwasher circuit. In older NYC kitchens, the dishwasher and garbage disposal sometimes share a circuit that is easy to trip. (3) If the display is blank, check that the control lock (child lock) is not active — hold the lock button for 3 seconds to toggle it on most brands. (4) Unplug the dishwasher for 5 minutes, then restore power. This resets the control board and clears most software-related faults. If none of these resolve the issue, the door latch, thermal fuse, or control board requires inspection by a technician.
