How to Fix / Troubleshooting
Safety: Turn off and unplug the unit before draining water.
- Drain water: Place a shallow pan under the lower rear drain outlet. Remove the drain cap and allow all water to drain. Reinstall the cap securely.
- Continuous drain setup: If using a continuous drain hose, ensure it slopes downward with no kinks and that the end is not submerged in standing water.
- Clean drain path: Remove the rear panel to access the condensate tray. Clean out any slime, mold, or debris blocking the drain outlet.
- Check float mechanism: Verify that the float moves freely and is not stuck in the up position. Clean and reposition if necessary.
- Test level switch: If P1 persists after draining and cleaning, test the water level switch or sensor with a multimeter and replace if faulty.
