What is actually going on
On the K line a leak is nearly always the defrost drain rather than a sealed-system fault, and this platform puts the drain outlet where a slug of ice can hold the whole melt back for days before anything reaches the floor. The brand-generic advice is right about the cause; what changes here is the access, because on the models listed in the table on this page the trough is reached from inside the freezer rather than from behind the cabinet.
What you are seeing
- The leak follows a big shop or a hot day — A cabinet filled with warm food runs longer, produces more melt, and overwhelms a drain that copes the rest of the time.
- Water is standing under the crisper drawers — Lift the drawers out: a shallow pool in the moulded base means the melt is backing up inside rather than escaping at the rear. The K line is no worse than its siblings here, but it is no better either.
- Water appears each time the dispenser is used — The drip does not stop when the lever is released. That is the inlet valve seat, and it will not improve on its own.
- Water runs down the inside of the rear wall — Vertical wet tracks on the back panel that dry and return. Warm humid air is meeting a cold surface inside the cabinet.
- The kick plate at the base is wet on the inside — Behind the base grille is where a mis-routed drain hose puts its water, and nobody looks there until everything else is clean.
- NEAR MISS — the water is soapy or coloured — That is coming from something else in the room. A clean appliance leak is clear and odourless.
- NEAR MISS — the cabinet is warm as well as wet — Warm plus wet means the whole cabinet has thawed. Treat it as a cooling failure and the water takes care of itself.
Causes, most likely first
- A failed defrost heater or its control — First — and it is not close. Genuinely last, and it produces a different picture: a thick frost sheet that never clears rather than periodic clean water. When the heater does fire after a long failure, the whole backlog arrives at once. The K line puts this within reach without a teardown.
- A leaking water supply line or its fitting — Then this. Compression unions loosen with cabinet vibration, and a plastic line that has been pinched behind the machine splits at the crease rather than at the fitting.
- A humid room and a machine working beyond its range — Next after those two. High ambient humidity produces condensation faster than any drain can clear it. It is a placement problem rather than a fault, and it is seasonal. Owners of the models listed in the table on this page describe this in almost identical words.
- A failed or poorly seating door gasket — Fourth. A gasket that no longer pulls flat lets room air in continuously; the moisture in that air condenses on the coldest surface it finds and runs down inside.
- A cracked or displaced drain pan — Rarer again. The pan under the cabinet takes knocks from every move and a hairline crack empties it onto the floor as fast as the melt arrives.
The diagnostic order
- Empty the freezer and inspect the rear panel — A flat slab of ice on the floor of the compartment, or frost concentrated at one corner, points at the drain outlet directly above it.
- Watch the cabinet through one full defrost interval — If water appears on a schedule rather than continuously, the defrost cycle is the driver and the drain is the fault. On these models the panel comes away before anything else does.
- Find where the water actually starts — Dry everything, lay kitchen paper along the door line and behind the cabinet, and read it in the morning. Front means drain, back means supply.
- Check the cabinet is sitting level — Levelling matters more here than owners expect: the trough has very little fall, and a forward tilt defeats it.
Safety first
Safety
Two hazards matter on this appliance: stored electrical charge and the sealed system. Unplug the appliance or switch off its breaker before removing any panel, and leave anything carrying refrigerant to a licensed technician with recovery equipment.

When to stop and book a visit
Book a visit if the frost sheet rebuilds within days of a full clear-out: that is a defrost control fault rather than a blocked drain, and it will keep flooding the cabinet until it is repaired. Also call if the floor covering has started to lift, because the leak has then been running longer than the symptom suggests.
