Refrigerators

Refrigerator leaking water onto the floor

Water pooling under or in front of the fridge is most often a clogged defrost drain or a cracked water line, both of which are usually fixable without replacing the fridge. Locating where the water first appears narrows down the cause.

Symptoms

  • Puddle of water in front of or under the fridge
  • Water inside the fridge pooling in the bottom drawers
  • Dripping sound from inside the fridge walls
  • Water appears mainly after the defrost cycle runs

Likely causes

  • CommonClogged defrost drainFood debris or ice can block the small drain hole at the back of the freezer, causing melted frost to overflow inside instead of draining away.
  • CommonCracked or disconnected water lineIf the fridge has an ice maker or water dispenser, a damaged supply line can leak slowly at the connection or valve.
  • PossibleBlocked or full drain panThe pan underneath the fridge that catches condensation can overflow if displaced or too full.
  • PossibleDoor not sealing, causing excess frost and meltA bad gasket lets in humid air that frosts up and later melts faster than the drain can handle.

What to do

  1. Unplug the fridge and pull it out carefully to check underneath for the drain pan and water line connections.
  2. Locate the defrost drain hole inside the freezer, usually at the back or bottom, and check for ice or debris blocking it.
  3. Clear the drain using warm water flushed through with a turkey baster or a pipe cleaner, being gentle to avoid pushing debris further in.
  4. Check the water line running to the ice maker or dispenser for cracks, kinks, or loose fittings, and tighten or replace if needed.
  5. Check that the drain pan sits properly and isn't cracked or overflowing.
  6. Check door gaskets for gaps that could be letting in extra humidity.
  7. Run the fridge for a day after clearing the drain and monitor for recurring leaks.
