What a leak means on the CCUL line
On the CCUL line the overwhelming majority of leaks are defrost water that has not reached the tray. The drain at the back of the compartment blocks with debris or freezes, the water backs up, and it appears under the crisper or on the floor at the front. That is an owner fix. The other causes — a cracked tray, a supply connection, a door that sweats — are found by looking at where the water actually is. The CCUL line covers sixteen model numbers, all listed in the table below. Check the rating plate inside the door before you order a part, because the family name alone will not get you the right one.
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.
Ranked causes on these models
- Blocked or frozen defrost drain — First on this family and the cause of most leaks on any cabinet with automatic defrost. Debris and food particles reach the drain hole, block it, and the melt water backs up into the liner instead of running to the tray.
- Drip tray overflow, displacement or cracking — Second. The tray sits over the compressor so the heat evaporates the water; a tray knocked askew when the unit was moved, or cracked with age, simply puts that water on the floor.
- Condensation from a failing door seal — Third. Warm humid air entering past a hardened gasket condenses on the cold liner and runs down, which looks exactly like a leak and gets worse in summer.
- Supply line, inlet valve or filter head on plumbed models — Last. Not every model in this family is plumbed, but where one is, the connections at the back are the leak that reaches the floor without ever appearing inside.
Check in this order, and why that order
- Dry everything and lay paper down — Inside on the liner floor and outside under the cabinet. Where it wets first is the diagnosis.
- Empty the bottom of the cabinet and find the drain — At the base of the rear wall. Debris or ice there settles it without moving the unit.
- Flush with warm water from a jug — Never a wire. The tube below the hole is soft plastic and a puncture leaks where nobody can see it.
- Check the lean with a level — Slightly back is right. Forward sends every overflow onto your floor and makes a small fault look like a big one.
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. Treat a leak that has soaked into insulation or flooring as urgent rather than cosmetic. Where the model is plumbed, close the supply shut-off before touching any connection, and remember a wet tiled floor and a heavy cabinet make moving it a two-person job.

Where the owner line is on these models
The owner line on these models is the drain and the tray. Clearing a blocked drain, thawing a frozen one, levelling the cabinet, reseating a tray and paper-testing the gasket are all yours, and they resolve the large majority of leaks. Call when the drain blocks again within weeks, when the tray is cracked, when a supply connection weeps on a plumbed model, or when water has reached insulation or flooring. Anything involving the defrost heater, the defrost control or the inlet valve is diagnosed on a live appliance behind a panel. The sixteen models listed share this diagnosis but not their part numbers, so have the rating plate to hand before the visit is booked.
