Start here
A leaking WD unit is telling you where its meltwater is going, not that it is broken. The drain path carries the whole of the defrost melt, so it is where a leak on this line almost always starts, so the ranking below departs from the brand-generic order. Start with a blocked condensate drain path and leave a split drain hose or a failed seam until everything cheaper has been excluded.
The observables
- Water appears at about the same time each day — Following a cycle rather than following use, which narrows the cause considerably.
- A puddle at the front, under the door line — It re-forms within a day of being wiped, and the floor behind the unit stays dry.
- Standing water on the compartment floor — Enough to see, sitting in the channel rather than spread across the base.
- NEAR MISS - water only once, right after a move — A unit laid down or carried warm sheds what it was holding. One puddle after a move is not a fault; a second one is.
Causes, most likely first on this line
- A blocked condensate drain path — The leading cause on these models: a restricted drain does not stop the water, it delays it. The melt pools where it cannot be seen, then arrives all at once as a puddle that looks far bigger than the fault behind it.
- An unseated drain plug or grommet — Second: this fault reads exactly like a cracked cabinet, which is why it is worth ruling out first: the water appears outside the compartment with the inside apparently dry.
- Warm air getting past the door or lid seal — Third, and worth excluding before going further: a compact cabinet has one gasket doing all the sealing, and warm room air that reaches a cold surface gives up its moisture there. A gasket that has taken a set, or that is held open a fraction by a shelf or a full basket, condenses water continuously without ever letting the cabinet warm enough to be noticed.
- A split drain hose or a failed seam — It ranks last for the usual reason: it is rare, and every cheaper cause above it explains the same puddle.
The order to work in
- Clear and test the compartment drain — Empty the compartment, find the outlet in the floor, and pour a little warm water at it. If it stands rather than draining, that is the fault and nothing further needs checking.
- Check the drain fitting is seated — Check the underside for a plug that has been left out entirely after a clean; the water will be arriving directly under it.
- Test the seal along its whole length — Close the door on a strip of paper at several points and pull. Where it slides out with no resistance the gasket is not making contact, and that is where the condensation forms.
Before any panel comes off
Safety
Isolate the unit at the plug or the breaker before any panel comes off - a capacitor can hold a charge after the power is off. Mop the floor first: standing water underneath a cabinet you are about to tip or move is how this job hurts people.

When this stops being owner work
Call when the leak survives a cleared drain and a level cabinet, and call immediately if you find water where the supply lead enters or under the machinery end. Water reaching insulation gets worse every week it is left, so this is not one to watch for a month.
