Possible Causes

Drain hose installed incorrectly, Hose end submerged or elevated, Clogged drain adapter, Internal drain path partially blocked

How to Fix / Troubleshooting

Safety: Unplug the unit and remove water before working on the drain system.

  • Verify hose connection: Ensure the hose is firmly attached to the continuous drain outlet and any rubber plug inside the bucket port is removed (per manual).
  • Ensure downward slope: The hose must run downhill with no loops or upward sections. Shorten if necessary.
  • Check hose outlet: The end of the hose should not be submerged in water or sealed; this can cause backpressure.
  • Clean drain adapter: Remove and clean the drain adapter and internal port to clear any sludge.
