The short answer
On a Capital built-in refrigeration column this complaint is usually a blocked defrost drain rather than the failure owners fear, and where it is not, a column door that has dropped out of adjustment takes most of the rest. A column is built into the cabinetry, ducted to a grille and levelled to the millimetre, so installation faults live on for years and present as cooling faults. The checks below are ordered to match, and the first of them needs no tools at all.
What you observe
- Water pooling under the salad drawer — Meltwater that could not reach the drain at the back of the liner.
- Water at the front edge, under the door — Almost always a cabinet tilted forward, or a seal drawing air in at that point.
- NEAR MISS - the fluid is oily or has a sharp smell — That is not defrost water. Switch the cabinet off and leave it alone until it has been looked at.
Causes, most likely first on this brand
- A blocked defrost drain — Top of the list here: the drain hole is small, it sits at the lowest point of the cooling surface where crumbs and label paper collect, and once it closes the meltwater has to go somewhere - forward, into the cabinet.
- A column door that has dropped out of adjustment — Second here: a heavy door on adjustable hinges only has to fall a fraction for the gasket to stop touching at one corner, and warm room air walking in there condenses where you eventually find the water.
- A cabinet standing nose-down — Third, and worth the two minutes: these are light enough to be set on carpet, on a shelf or on a floor that slopes, and tilted forward the meltwater never reaches the drain at the back at all.
Check in this order, and why
- Find the drain at the back of the liner and test that it runs — It is the likeliest cause and it clears in minutes, so nothing below it is worth doing first.
- Check the door pulls onto its seal evenly at every corner — On a heavy door the fault is nearly always at one corner, and that corner is where the water starts.
- Check the cabinet is level or tilted very slightly back — A forward tilt sends water the wrong way along the liner floor, whatever else you fix.
What an owner can safely check
- Flush the drain gently with warm water — Use warm water and a soft flexible wire only. Never force a sharp tool into the hole.
Tools: warm water, soft wireAbout 20 min
- Close the door on a slip of paper and pull it out at several points — Where it slides out freely, the seal is letting humid air in and making the water you are mopping.
Tools: a sheet of paperAbout 10 min
- Level the cabinet with a very slight rearward tilt — The feet adjust on most cabinets; a shim under the front works on a fixed base.
Tools: spirit levelAbout 15 min
- STOP HERE if the next step means taking the rear panel off — Behind it are the evaporator and live terminals, and that is where owner checks end.
Before you open anything
Safety
Switch the column off at its breaker before removing the base grille or any panel - a built-in is often hard-wired or fed from an outlet behind the cabinetry, so unplugging is not an option. A capacitor can hold a charge after the power is off. Do not try to pull a column out of its opening alone; they are tall, heavy and anchored to the joinery.
When to call a technician
Call early on a built-in, and certainly once the drain has been flushed and the door checked without result. Water in a column reaches the cabinetry and the floor under it before it reaches you, so the economics here are different from a freestanding cabinet: the joinery is worth more than the visit.

What this page does not cover
This page covers built-in refrigeration columns as a class, not one model line or installation. Drain routing, base-pan design and grille dimensions differ by family, and where a family- or model-specific page exists it is linked below and is the more specific answer. Not here: part identifiers, clearance figures and panel-removal sequences.
