How to Fix / Troubleshooting

Safety first: Unplug the unit before tipping or disassembling. Mop up any spilled water to avoid slipping.

Step-by-step:

  • 1. Inspect tank: Remove the water tank and check for cracks or overfilling. Ensure the tank is not warped and seats properly.
  • 2. Clean drain channel: With the tank removed, locate the condensate outlet and channel above the tank. Use a small brush or pipe cleaner to remove slime and debris.
  • 3. Check continuous drain setup: If using a hose, ensure it is firmly attached to the drain port, slopes downward continuously, and is not kinked or blocked.
  • 4. Inspect internal pan: Remove the front/rear cover to view the internal drain pan under the evaporator. Look for cracks or misalignment. Replace the pan if damaged.
  • 5. Test for leaks: Reassemble, reinstall the tank, and run the unit while observing for drips. Adjust tank position if necessary.
