Possible Causes

Extremely humid environment, Continuous drain hose not installed or not working, Bucket not set up for continuous drain mode, Drain hose routed uphill

How to Fix / Troubleshooting

Safety first: Unplug the unit before adjusting drain connections.

Steps to reduce bucket filling:

  • Install continuous drain: If your Whynter model supports it, attach a suitable drain hose to the drain outlet and route it to a floor drain.
  • Ensure downhill flow: Make sure the hose slopes downward with no loops or high spots.
  • Check bucket position: Some models require the bucket to be in place even when using continuous drain. Ensure it is seated correctly.
  • Reduce moisture sources: Use exhaust fans in bathrooms and kitchens, and close windows during dehumidifier operation.
