The answer first
For the WCN series specifically, water turning up where it should not is most often a blocked defrost drain. The brand-generic page reaches the same first answer, but the order below it changes on this roster, because reaching the next part is not the same job here. All 6 of the causes below can at least be narrowed down without a tool, which is unusual and worth taking advantage of.
What you observe
- Damp in the salad drawers with nothing spilled — Condensation collecting at the coldest low point, which points at airflow and sealing.
- A pool of water on the floor at the front — Water that has run right through the cabinet, which usually means the drain rather than the supply.
- Water running down the inside of the back wall — The drain behind the panel is blocked and the meltwater is finding another way out.
- Water appears roughly twice a day and never otherwise — That rhythm is the defrost cycle, and it points straight at the drain.
- NEAR MISS — water arriving fast, cold and clean — That is the supply line, not meltwater. Shut the water off at the valve first, then read on.
Causes, most likely first on the WCN series
- A blocked defrost drain — Every frost-free cabinet melts its coil several times a day and has to send that water somewhere. Block the drain with debris or a plug of ice and the water backs up over the freezer floor and out of the door.
- The water supply line, its fitting or the inlet valve — A supply leak is clean, cold and fast, and it does not wait for a defrost cycle. The compression fitting at the back is the usual point.
- A door seal letting warm damp air in — Every gram of moisture that leaks in has to condense somewhere cold. A tired gasket produces steady damp and frost in the same corner, day after day.
- A cabinet standing out of level — Cabinets are designed to sit slightly back on their feet so the door swings shut and the drain runs the right way. Tip it forward and both stop working.
- The ice maker fill tube or its seal — A fill that misses the mould puts a small amount of water into the freezer every cycle, which arrives as a sheet of ice under the bin rather than as a puddle.
- Humid loading and open-door habits — Hot food put straight in, or a door held open while a meal is planned, puts a lot of water into a cold box, and it has to go somewhere.
Check in this order, and why
- Check level and the door seal in the same pass — They are both free, both quick, and each decides where water goes even when neither caused it.
- Decide first whether the water is clean and cold or is meltwater — A supply leak needs the water shut off immediately. Meltwater can wait until you have read the rest of the list.
- Clear the freezer floor and look for a lens of ice — Ice on the floor of the compartment is a blocked drain until proved otherwise.
- Dry everything, then watch across a full day — Most of this list is identified by when the water comes rather than by where it collects.
- Switch the ice maker off for a couple of days if there is one — It is the cheapest way to eliminate a fill-side leak without taking anything apart.
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. Refrigerant work is licensed work: the sealed system is not to be opened, tapped or topped up by an owner at any level of experience. Put back every panel, clip and cover you take off before the machine goes back on the supply.

When to call a technician
The line falls here: what you can see, reach and clear with the machine isolated is owner work; the sealed system, the compressor and anything that has to be measured rather than looked at is not. On this page that puts anything behind a fixed panel on the far side of the line.
