The short answer
Water under the crisper drawers or inside the cabinet floor is a blocked defrost drain, and that is often owner-clearable. Water at the back or a steadily growing puddle on a plumbed machine points at the supply line, the valve or the filter housing.
Where the water appears
- Under the crisper drawers — The classic blocked defrost drain.
- Ice sheet on the floor of the cabinet — Meltwater refreezing instead of draining.
- A puddle at the front of the machine — Overflow from inside running forward.
- Clean water at the back — A supply line or valve on a plumbed machine.
- Water in the tray at the compressor overflowing — The tray is cracked or displaced.
- Not this fault: condensation on the outside in a humid room — See the seal page.
Ranked by what is found
- Defrost drain blocked with debris or ice — First by a wide margin.
- Drain tray displaced or cracked — Second.
- Door seal leaking, so humid air condenses inside — Third.
- Supply line fitting loose on a plumbed machine — Fourth.
- Filter housing leaking after a filter change — Fifth, and usually a seating problem.
- Inlet valve leaking — Last.
Find the source in this order
- Take out the drawers and look at the cabinet floor — Water there names the drain.
- Locate the drain hole at the back of the compartment — A blockage is often visible.
- Check the tray under the machine — Displaced trays spill every defrost.
- On a plumbed machine, look behind for clean water — That is a different fault entirely.
Owner checks
- Empty the drawers and dry the cabinet floor — It shows whether the water returns from inside.
Tools: clothAbout 15 min
- Flush the drain hole with warm water — Debris and ice both clear this way.
Tools: warm water, turkey basterAbout 25 min
- Check the tray beneath the cabinet is seated and intact — It should sit flat under the compressor.
Tools: torchAbout 20 min
- Test the door seal with a sheet of paper — A leak condenses moisture inside the cabinet.
Tools: paperAbout 15 min
- Reseat a recently changed water filter — Most filter leaks are seating, not the part.
About 15 min
- Stop before removing the rear panel to reach the drain heater — It sits behind the evaporator.
Water around an appliance
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Keep the refrigerator at or below forty degrees Fahrenheit and the freezer at or below zero degrees Fahrenheit. Turn off the water supply before disturbing any fitting on a plumbed machine, never clear a drain with a sharp tool, and do not operate the appliance while standing in water.
When to call
Call when flushing does not clear the drain, because a drain that keeps freezing usually means a defrost fault behind the panel. Call promptly for any plumbed leak that continues after the fittings have been checked, and shut the supply off in the meantime. Persistent water under a cabinet damages flooring, so it is worth resolving quickly.
