- Inspect the drain hose along its full length; straighten kinks and re-route below the height limit in the manual.
- Disconnect the hose and flush with warm water; replace if interior is glazed with biofilm.
- If installed in a cold area, warm the space or move the dryer until thawed.
- If hose is clear and routed correctly, test the drain pump for continuity and clear blockage at the impeller; replace if seized.
- Reconnect, plug in, and verify code clears on a short cycle.
