What this means on these models
On the MTF line the important first question about a leak is not what is broken but whether the water is clean supply water or melt water. The model matrix on this page lists four model numbers under this family badge. Melt water means the drain path; supply water means a joint, and those two lead to completely different repairs.
What you observe
- A sheet of ice on the freezer floor — The same blockage seen from the other compartment — melt water freezes where it stands before it can drain.
- Water at the front of the floor, usually after a cycle — A puddle that returns hours after being mopped tracks the defrost cycle rather than the supply.
- A steady drip at the back, near the floor — Water at the rear is a supply-side or pan question, and the two are told apart by whether the drip continues with the water off.
- Water running down the inside of the door liner — Droplets on the shelves and running down the inside of the door, which is condensation rather than plumbing.
- NEAR MISS — water only in the drain pan at the back — A wet drain pan is the expected end of the defrost path, not a fault.
What it usually is, in order
- Supply line, inlet valve or dispenser tubing leaking — Ranked first on the MTF line because four model numbers is enough of a span that two units with the same badge can differ in what is fitted — a pressurised joint is the only source here that does not stop on its own, so it is ruled out first regardless of how likely it is.
- Blocked or frozen defrost drain — Second, and the commonest cause once a pressurised leak is excluded: melt water backing up inside the liner and finding its way forward.
- Door seal or a door not closing fully — Third — it explains water on the liner and shelves rather than on the floor, and it is fixed at the gasket rather than the drain.
- Drain pan cracked or off its seat — Last, and usually discovered while the unit is out for one of the checks above.
Check in this order, and why
- Close the household water valve and leave it an hour — A leak that stops is supply water; one that continues is melt water, and the two lead in opposite directions.
- With the water off, look for any remaining wetness at the rear — What is left is the pan or the drain tube rather than a live joint.
- Clear the defrost drain at the freezer floor — Third, and the likeliest cause of water inside the cabinet once supply is excluded.
- Paper-test the gasket all round both doors — Paper-test both door gaskets last, because a door fault shows on the liner rather than on the floor.
Before any panel comes off
Safety
Switch the appliance off at the breaker or unplug it before working on it, and dry the floor first; a capacitor can hold a charge after the power is off. Never clear a frozen defrost drain with a metal probe pushed hard — the tubing behind the liner is thin. Warm water down the drain and patience do the job without turning a blockage into a hole.

The service-call line
The condition is whether the leak survives the household water being shut off. If it does, it is melt water and the drain and the gasket are reasonable owner work on these models. If it does not, a joint is involved and it is worth having remade properly. Damp flooring makes it urgent either way.
