Possible Causes

Frozen defrost drain tube, Debris blocking drain hole, Improper cabinet leveling causing water to pool

How to Fix / Troubleshooting

Safety: Unplug the freezer before defrosting or removing panels. Use towels to absorb water.

Steps to clear internal water/ice:

  • Remove ice: Take out baskets and chip away loose ice carefully with a plastic scraper. Do not use sharp metal tools.
  • Access drain hole: Remove the rear interior panel to expose the evaporator tray and drain hole at the bottom.
  • Defrost the drain: Pour warm (not boiling) water into the drain hole using a turkey baster until the ice plug melts and water flows freely.
  • Clean the tube: If accessible from the back, gently run a flexible plastic line or pipe cleaner through the drain tube to remove debris.
  • Level the unit: Ensure the freezer is level so defrost water flows properly to the drain.

Note: Regularly check and clean the drain area to prevent recurring ice buildup.
