How to Fix / Troubleshooting

Safety: Unplug the unit before testing switches.

  • Verify bin not full: Empty the bin and confirm the bin full sensor is not blocked or stuck.
  • Inspect float: Check the water level float switch for free movement. Clean and reposition if stuck.
  • Reset control: Disconnect power for 5–10 minutes to clear any latched error. Restore power and attempt to start a cycle again.
