Water Is Leaking Behind Refrigerator – 5 Causes – What To Check – How To Fix?





Water leaks from back of refrigerator. I recently noticed a large puddle of water under my refrigerator. I pulled the fridge out and can see the water is coming from the back of the refrigerator and running forward. The refrigerator is leaking water from the back or possibly underneath. What part is the most likely to leak? The water valve on the fridge or the water valve on the wall behind the refrigerator? I cannot figure out which part or area is leaking.

If you have water leaking behind or underneath your refrigerator it could be a few different parts or components causing the leak. First, you will need to check to see if the leak is coming from the refrigerator or the water valve on the wall behind the refrigerator.

Here are 5 components to troubleshoot what may be causing the water leak under or in the back of your refrigerator:
Check the defrost drain in the fridge, the water inlet valve at the bottom of the fridge, the water ON OFF valve on the wall behind the refrigerator, the condensation pan (drain pan), and the water line going from the wall to the refrigerator for damage or the possibility of a loose part or component. See below for a detailed list of parts or areas of the fridge that may be the cause of the leak.







1 – REFRIGERATOR WATER SUPPLY LINE (WATER FROM WALL TO FRIDGE)

The water supply line (usually a plastic tube) behind the refrigerator may be damaged, slightly loose, or has pulled out from the wall or refrigerator. Use caution when sliding your refrigerator out from the wall as pulling it too far can pull the water line out! Check to see if the refrigerator water line is in good condition with no holes or rips. Check to be sure the water line is secure and has not been pulled out. If damaged, replace it. If loose, re secure it.

2 – WATER SHUT OFF VALVE (BEHIND REFRIGERATOR)

The water valve on the wall behind the refrigerator may be leaking. The water valve that supplies water to the refrigerator could be loose, clogged, or damaged. Check the water valve and replace if needed. If you need to replace the water valve on the wall behind the refrigerator, remember to shut the water off to the complete home before doing so. Replace the valve as stated on the instructions that came with it.

3 – REFRIGERATOR WATER INLET VALVE (BACK BOTTOM OF REFRIGERATOR)

The refrigerator water inlet valve may be loose, faulty, or clogged. This is the valve at the back bottom of the refrigerator where the water line attaches into. This valve supplies water into your refrigerator for water and ice. If this valve is damaged, cracked, or the water line is not fully connected, it will leak. If you find the water inlet valve to be faulty, remember to turn the water valve on the wall off and remove power to the refrigerator before removing and installing a new water inlet valve.

4 – DEFROST DRAIN LINE OR DRAIN HOLE (IN FREEZER)

Check the defrost drain line or drain hole in the freezer/refrigerator. The defrost drain can freeze up or become clogged with debris. If this happens, this causes the water to not be able to drain out and therefore water can drip down to the very bottom of the fridge compartment or overflow onto the condensation pan. When enough water accumulates, the water will eventually drip onto the floor. Fix frozen defrost drain tube in fridge freezer here.

5 – REFRIGERATOR CONDENSATION PAN OR DRAIN PAN (AT BOTTOM OF REFRIGERATOR)

Be sure the condensation pan (drain pan) at the very bottom of the refrigerator is clean. This pan sits at the very lowest point in the refrigerator near the ground. This pan’s purpose is to catch any dripping water. The condensation pan catches any water dripping and the heat from the refrigerator compressor evaporates the water. If this pan becomes dirty or clogged, it can overflow water and leak onto the floor. Consult your refrigerator manual to find out how to access the pan and clean it out. Once cleaned be sure to place it back in the correct position as if it is not seated correctly this can cause water leakage. Find your refrigerator manual here.
