Dishwasher stops mid-cycle and all lights go off, then may resume later.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Safety First: Turn off power at the breaker before inspection.

Check junction box wiring: Tighten all wire connections and replace any burnt components.
Inspect door latch: Ensure the latch is tight and the door does not sag. Replace latch if the switch is intermittent.
Control board inspection: Look for signs of overheating on the control board. If present, replace the board.
