How to Fix / Troubleshooting

Safety First: Disconnect power before inspecting wiring or controls.

  • 1. Note when it stops: Determine if the stoppage occurs during wash, drain, or dry to narrow down the component.
  • 2. Inspect wiring harness: Check connectors at the control board, door switch, and pumps for looseness or heat damage.
  • 3. Check door switch: Ensure the door is not flexing and opening the switch mid-cycle. Replace the latch/switch if intermittent.
  • 4. Assess motor temperature: If the circulation pump is extremely hot when the unit stops, it may be overheating and should be replaced.

Persistent mid-cycle failures often require professional diagnosis of the control board.
