The answer first
Water under a refrigerator comes from one of three places: the defrost drain, the water line, or condensation. On this machine the first suspect is defrost drain blocked.
What you observe
- Water under the crisper drawers inside the cabinet — Classic blocked defrost drain: the water backs up and over.
- A puddle on the floor at the front — Water has run forward under the cabinet, which usually means the drain or the pan.
- A puddle at the back or under one corner — Points at the supply line, the valve or a cabinet that is out of level.
- NEAR MISS — the cabinet is warm as well as wet — Treat that as a cooling failure first; the water is a consequence of the ice, not a leak.
Causes, most likely first on a SKS refrigerator
- Defrost drain blocked — The drain carries melt water from the evaporator to the pan, and food debris or ice blocks it. Ranked first on a SKS refrigerator: it is the commonest leak on any cabinet, and the water is defrost water rather than supply water.
- Door seal leaking, so humid air condenses inside — Warm room air entering past a tired gasket condenses on the cold walls and runs down them.
- Ice maker fill overshooting or the fill tube spraying — A fill that runs long, or a fill tube partly blocked with ice, puts water outside the mould.
- Cabinet out of level, so the drain does not fall to the pan — The drain relies on gravity, and a cabinet tipped the wrong way holds the water instead of shedding it.
Check in this order, and why
- Look for water or ice under the crisper drawers at the back of the cabinet — Pour a little warm water into the drain opening and see whether it clears.
- Close the door on a sheet of paper right round both doors — Look for beads high on the walls: that is condensation, not a leak.
- Look for a sheet of ice under the bin or water tracking down the freezer wall — Switch the ice maker off for a day: if the water stops, it is answered.
What an owner can safely check
- Empty the lower shelves and flush the drain opening at the back with warm water from a turkey baster — Warm water clears an ice plug and most debris. Never force wire down the drain.

- Test both door seals with paper, then wash the gaskets and check the doors close square — A gasket that is clean, warm and sealing stops the condensation at source.
Tools: sheet of paper, warm soapy waterAbout 20 min
- STOP HERE if the next check needs a panel off or a meter on live terminals — That is where the owner checks end and a service call begins, whatever the ranking says.
Before you open anything
Safety
Unplug the refrigerator or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Leave the door switch wired as you found it. Never take a knife, a screwdriver or a heat gun to frost on an evaporator: the tubing behind it is thin, pressurised, and a puncture ends the appliance. Empty a loaded cabinet before you move it.
When to call a technician
Owner work here is the drain, the pan, the seals and the levelling. A weeping valve, a split line inside the cabinet and a drain blocked beyond the opening are technician work — and a mains leak should have the supply valve shut immediately. Door and hinge work on a panelled machine is a trained job: the panel weight is carried by the hinge springs and a mis-set hinge damages the cabinetry as well as the appliance.

What this page does not cover
This page covers the SKS refrigerator as a class, not one family or model line. Where a family- or model-specific page exists for your unit it is linked above and it is the better answer — read it first. Deliberately not here: part numbers, wiring colours, panel removal order and torque figures, all of which differ between families under one nameplate.
