Possible Causes

Blocked defrost drain hole, Frozen drain tube, Cracked internal liner allowing water behind panels, Door gasket leaking warm air causing excess frost melt

How to Fix / Troubleshooting

Safety: Unplug the freezer before removing internal panels or using hot water.

  • Locate drain: On frost-free Zanussi freezers, a small defrost drain hole is usually located beneath the evaporator behind the internal rear panel.
  • Clear blockage: Use a soft pipe cleaner or flexible plastic rod to gently clear debris from the drain hole. Do not use metal objects that can puncture the liner.
  • Flush with warm water: Using a turkey baster or syringe, flush warm (not boiling) water through the drain until it flows freely into the drain pan above the compressor.
  • Check drain tube: From the rear, inspect the drain tube leading to the drip tray. Ensure it is not kinked or frozen.
  • Inspect door seal: A poor seal can cause excessive frost and meltwater. Replace the door gasket if necessary.
