The short answer
Water on the floor at an A Premium MK cabinet is a plumbing question first and a refrigeration question second, and where the water sits tells you which. Every refrigerator makes water on purpose — defrost meltwater has to go somewhere, and there is a drain and a tray to take it. A leak is almost always that path blocked or a supply line that has let go, and the two look nothing alike once you know where to look. The table below lists three models for this family, and they are close enough that the fault behaves the same way across all of them; what differs between them is parts rather than diagnosis.
What you observe on these models
- Water pooling inside, under the crisper drawers — That is defrost meltwater that has not reached the drain, so it has run forward into the cabinet instead.
- Water on the floor at the front of the cabinet — It has come over the front lip, which means the inside pool has been building for a while.
- Water at the back, near the wall — That is the supply line, the inlet valve or an overflowing drain tray, and it is a different repair entirely.
- Ice forming in the bottom of the freezer or under the drawers — The drain is frozen rather than merely blocked, and the water is freezing where it stands.
- NEAR MISS — water only after a hot, humid day with the door opened often — Condensation on the seals and shelves is normal in that weather and is not a leak.
Causes, most likely first on the MK family
- The water supply line, its fitting or the inlet valve — This is the only part under mains pressure, so when it goes the volume is far larger than anything the defrost system can produce, and it goes at the back where nobody looks. The three models of the MK family share this construction, so what ranks first on one of them ranks first on all of them.
- A blocked or frozen defrost drain — It is a narrow passage at the coldest point of the machine, carrying water that arrives with debris in it, so it is the part of the water path most likely to close up — and it does so gradually.
- A cracked or displaced drain pan — The pan lives under the cabinet where it is knocked during every move, and a cracked pan drips exactly where the floor is hardest to see.
- Door seals letting warm air in — Warm, moist air condensing on cold surfaces produces standing water without anything having failed, and a seal that has taken a set no longer grips in the corners.
Check in this order on these models, and why
- Pull the cabinet out and check the supply fitting and the valve body are dry — Checked early whenever the water is at the back, because a pressurised leak does not wait.
- Find where the water sits inside and work back to the drain outlet — First, because water inside the cabinet nearly always means this and nothing else.
- Look underneath at the pan with a torch — Done alongside the supply check because both live in the same place.

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 and a powered appliance together are the hazard here: switch the machine off at the breaker before you kneel in a wet area or reach behind the cabinet, and dry the floor first. Close the water shut-off valve before undoing any fitting, and never stand a cabinet back on a wet floor covering that has started to lift.
When to call a technician
Call a technician when the drain has been cleared and the water comes back, or the moment you find the leak is on the supply side rather than the defrost side. Call immediately if water is reaching an electrical outlet, a floor void or a room below, because the cost of a leak is almost never the appliance repair and is almost always what the water reached while nobody knew it was there.
