Common Causes of a Fridge Leaking Water
Finding a puddle of water under or inside your fridge is alarming but usually not serious. The majority of fridge water leaks have straightforward causes and can be resolved in a single engineer visit.
Blocked Defrost Drain
This is the most common cause of water pooling at the bottom of a fridge or underneath it. During defrost cycles, water from the evaporator coils drains through a small hole at the back of the fridge into a drip tray. If this drain blocks with ice, food debris, or bacteria, water overflows into the fridge compartment.
Engineers can unblock the drain quickly, usually in under an hour. If the blockage is recurring, a thorough clean or drain modification may be recommended.
Damaged Water Supply Line (Fridge Freezers with Water Dispensers)
American-style and plumbed-in fridge freezers have a water supply line. If this line becomes cracked, loose at a fitting, or frozen, it can leak. Turn off the water supply to the fridge and call an engineer promptly.
Condensation from a Damaged Door Seal
A worn door seal allows warm, humid air in. When this moisture condenses on the colder internal surfaces, it can accumulate and eventually drip. Replacing the door seal solves both the condensation and any temperature issues caused by the seal failure.
Cracked or Overflowing Drip Tray
The drip tray at the bottom of the fridge collects condensation and defrost water, which normally evaporates. If the tray cracks, or the appliance is on an uneven surface causing spillage, water will pool underneath. This is often a DIY fix — pull the fridge out and check the tray.
What to Do
Mop up the water, check the door seal visually, and look for obvious signs of a blocked drain at the back of the fridge compartment. Then get free quotes from local engineers to diagnose and fix the root cause.
