Possible Causes

How to Fix / Troubleshooting

Safety: Unplug the cooler before working inside. Water and electricity are a dangerous combination.

Steps to clear the drain:

  • Locate drain hole: Inside the cabinet, at the bottom of the rear wall, locate the small defrost drain hole or channel.
  • Clear blockage: Use a soft pipe cleaner, cotton bud, or flexible plastic strip to gently clear any debris. Do not use sharp metal objects.
  • Flush with warm water: Using a syringe or turkey baster, flush a small amount of warm (not boiling) water through the drain to melt any ice and carry away debris.
  • Check rear drain tube: At the back of the unit, locate the drain tube leading to the evaporation tray above the compressor. Ensure it is not kinked or disconnected.
  • Clean drip tray: Empty and clean the evaporation tray if accessible to prevent overflow and odors.

Tip: Regularly wiping condensation and ensuring the door is not left open for long periods will reduce drain blockages.
