The short answer
Water from an integrated column is usually meltwater that could not reach its drain, but on a plumbed column the first thing to rule out is the supply line inside the joinery, because that is the one that damages the kitchen. Establish whether the water is inside the appliance or under the cabinetry before you do anything else.
What you observe
- Water pooling under the lowest drawer — Meltwater backing up because the drain is blocked.
- Damp, staining or a swollen plinth beside the column — Water in the joinery, which points at the supply line.
- Water running down the interior rear wall and stopping there — The channel works and the drain below it does not.
- NEAR MISS — water with soft food and a warm column — Treat it as a cooling failure; the water is only the evidence.
Causes, most likely first on this brand
- A blocked defrost drain — First in frequency: the drain is small, it sits at the lowest point of the rear wall, and salad leaves and label paper stop it. Meltwater then runs forward into the compartment.
- A supply-line fitting inside the joinery — Second in frequency and first in consequence on a plumbed column. A slightly under-tightened compression fitting weeps into a cabinet base and is found by the smell rather than the sight.
- A displaced drain hose or tray behind the plinth — Third, and common after installation, because both are reached only from the front and both are knocked as the column is pushed home.
- A door that is not sealing — Fourth, always contributing rather than sole: a furniture door pulling the appliance door out of true admits humid air, which makes more meltwater than the drain was sized for.
Check in this order, and why
- Decide whether the water is inside the appliance or in the joinery — Two different faults with two very different urgencies.
- If the column is plumbed, close the supply valve first — Stop the damage before diagnosing anything else.
- Find and flush the drain at the base of the rear wall — It is the leading cause of water inside the compartment.
- Check the tray and hose behind the plinth last — They explain water under the cabinet rather than inside it.
What an owner can safely check
- Close the water shut-off valve if water is outside the appliance — This is the difference between a repair and a kitchen refit.
Tools: torchAbout 10 min
- Empty the lowest drawer and dry the compartment floor — You need a clear view of the drain at the back.
Tools: clothAbout 15 min
- Flush the drain with warm water and a soft wire — Work gently; never force a stiff or sharp tool into it.
Tools: warm water, soft wireAbout 25 min
- Check the tray and hose behind the plinth grille — The hose should discharge over the tray, and the tray sit square in its clips.
Tools: torchAbout 20 min
- Dry the cabinet base and check for swelling — Damp joinery holds water long after the leak is cured.
Tools: towelsAbout 30 min
Before you open anything
Safety
Switch the column off at its breaker before flushing the drain or working behind the plinth — a capacitor can hold a charge after the power is off, and you will otherwise be handling water beside a live appliance inside joinery. Never push a sharp probe into the drain, because tubing runs behind that wall. An integrated column with its furniture door fitted must not be drawn out alone.
When to call a technician
Call at once if you suspect the supply line or find damp in the cabinet run, because that is a damage problem rather than an appliance problem. Call also when the drain runs clear, the tray and hose are seated, the door seals, and water still appears. Oily fluid rather than clear water means the sealed system and the column should be switched off until it has been inspected.

What this page does not cover
This page covers fully integrated refrigeration columns as a class rather than one model line. Deliberately absent here: drain, hose and tray part identifiers, supply fitting sizes, niche dimensions and gasket profiles, which differ by family and belong on the family or model page.
