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

Failed main relay or triac on control board, Open neutral or line connection to fan/heater, Safety interlock not detected as closed

Safety first: Unplug the unit before opening.

Interlock:

Verify the basket or door is fully closed and the interlock switch operates correctly. Replace the switch if faulty.

Control board and wiring:

Inspect wiring from the control board to the fan and heater for loose or burned connectors.
Check the main relay on the control board for visible damage. If the relay does not click when a cycle starts and power is present at its coil, replace the main control board.
