A common cause of fridge leaks is damage to the water supply line. If the line is cracked or worn, water can escape and form puddles around your appliance. Most supply lines are made of nylon, and a damaged line will need to be replaced. In some cases, the problem may be with the seals, especially the threaded compression fittings at both ends of the pipe.

✔ Clogged Defrost Drain

A blocked defrost drain can also cause your fridge to leak. Over time, food particles and debris can accumulate in the drain hose, leading to ice buildup. When temperatures change, some of this ice melts and water starts pooling around your fridge. You can often fix this at home by flushing the drain with warm water using a turkey baster or funnel to clear the blockage.

✔ Frozen or Clogged Water Supply Line

The water inlet valve controls the flow of water to your fridge’s ice maker and water dispenser. If it becomes loose, cracked, or clogged with mineral deposits, it can start leaking, causing water to pool behind or under your fridge. A faulty valve can also reduce water pressure, which may affect ice production and the performance of your dispenser.

✔ Cracked or Overflowing Drain Pan

The drain pan catches excess water from your fridge’s defrost system and allows it to evaporate over time. If the pan is cracked or damaged, water can leak onto the floor instead of evaporating. High humidity or excessive condensation can also cause the pan to overflow. Regularly inspecting the drain pan for cracks and making sure your fridge has proper ventilation can help prevent leaks.

✔ Improper Fridge Leveling

The drain pan catches excess water from your fridge’s defrost system and allows it to evaporate over time. If the pan is cracked or damaged, water can leak onto the floor instead of evaporating. High humidity or excessive condensation can also cause the pan to overflow. Regularly inspecting the drain pan for cracks and making sure your fridge has proper ventilation can help prevent leaks.

✔ Overfilled or Leaking Ice Maker

An overfilled or leaking ice maker can cause water to drip inside your fridge or onto the floor. This usually happens because of a misaligned water supply line, a faulty inlet valve, or a malfunctioning ice maker mechanism. When the ice maker overfills, it can create blockages or leaks that lead to water buildup. Regularly checking the water line and ice bin can help prevent these issues.
