Find the water before the part
A leak on these cabinets is usually cheap to fix and expensive to leave. The defrost drain blocks, water backs up into the liner, and from there it reaches the floor, the cabinetry and eventually the insulation in the shell. The repair is a flush with warm water; the damage, if it runs for months, is not. The CCUK family as the table shows it is one model number. Work from the full number on the rating plate rather than from the family letters when you order anything.
What you actually observe
- Water pooling around the base of the door — Drain overflow reaching the front lip, or a gasket that is channelling condensation forwards.
- A steady drip at the back with the compressor running — Tray overflow, which is normal in humid conditions and abnormal if the tray is cracked.
- Food containers sitting in water — The drain again, and a reason to act promptly before the liner floor stains.
- Frost at the back wall plus water below it — The two halves of the same defrost fault, and the clearest version of it.
- NEAR MISS — a smell of damp with no visible water — Check the tray and under the cabinet before assuming food is the source.
Most likely first
- Blocked drain, by debris — First and cheapest: food particles migrate to the lowest point of the liner and stop there. A flush with warm water clears it.
- Blocked drain, by ice — Second, and a different fix: the cabinet has to be off and empty long enough to thaw completely, and repeated freezing points at the defrost system.
- Overflow and levelling — Third. Where the overflow ends up depends on how the cabinet sits, which is why a leak on the floor at the front is often a drain fault plus a lean.
- Condensation and supply connections — Last as a pair: one seasonal and harmless if managed, the other continuous and worth stopping at the shut-off before anything else.
Check in this order, and why that order
- Ask what changed recently — A move, a new level, a filter change, hot humid weather, or a door left open. Each maps onto a different cause.
- Check the front lip and the floor under the door — Water there with a dry interior usually means the drain has overflowed rather than a seal has failed.
- Feel the gasket all the way round — Hard, flattened or torn sections at the hinge corners are where condensation starts on cabinets of this age.
- Stop at the drain tube and the tray — Anything beyond — heaters, the defrost control, the inlet valve — is diagnosed on a live appliance behind panels, and that is service work.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Water on the floor and electrical parts at the back of the cabinet are a bad combination, so unplug the unit before mopping underneath or pulling it out. Do not clear a frozen drain with a metal wire or a heat gun: the drain tube is soft plastic and a punctured tube leaks permanently and invisibly.

Where the owner line is on these models
Treat continuous water differently from cyclic water. Cyclic water is the defrost system and it is usually yours: flush the drain, level the cabinet, reseat the tray. Continuous water on a plumbed model is a supply fault: close the household shut-off first and book the visit second, because that one keeps running whether or not anybody is home. One model number carries the CCUK designation, so when you book the visit give the full number from the rating plate rather than the family letters — it is what decides which parts the technician brings.
