Possible Causes

Internal tank full, Blocked drain hose, Faulty water level sensor, Unit not properly leveled

How to Fix / Troubleshooting

Safety first: Turn off and unplug the unit before draining.

  • 1. Drain water: Open the lower drain plug and drain water into a shallow pan until flow stops.
  • 2. Check continuous drain: Ensure the hose is not kinked and slopes downward.
  • 3. Clean float and sensor: Access the base pan, clean the float mechanism, and ensure it moves freely.
  • 4. Level the unit: Adjust the unit so it is slightly tilted toward the drain side.

If P2 persists with no water present, the water level sensor or float switch likely needs replacement.
