Condensate Drain and Pan

Water in front of a wine cooler or undercounter unit looks alarming and is often a simple fault. On Mercer Island the damp lake air that comes in with each opening of the door leaves more moisture on the coil than a drier kitchen would, so the drain has more to carry.

Where the water is meant to go

A cold coil pulls moisture out of the cabinet air, and that water has to leave. On the units we work on it leaves by a tube to a shallow pan near the machinery, where the heat of the running unit evaporates it. The owner guides for wine and undercounter models do not draw that route, so treat it as the usual pattern rather than a map of yours.

Reading the leak

Water on the floor at the kickplate points to the pan or the path to it. Water on the cabinet floor or under the lowest rack points to a drain that has blocked, so meltwater backs up inside. Water running down the outside of the glass is room air condensing on a cold door, not a drain fault; the note on fogged glass deals with it. A humid room and a cabinet packed to the back wall both add to the water a coil has to shed, and for a full-size built-in the note on water and ice inside a built-in goes further.

What you can do

Dry the floor and the cabinet, then watch where the water comes back first. Check that the door swings shut on its own with nothing holding it open. Do not push wire into a drain opening or take off panels beyond the kickplate. Water that keeps returning is booked as wine storage repair and priced once we know where it stops.
