The short answer
The MS roster records a single model, so nothing on this page has to be hedged across variants, and it is recorded as a single catalogue number with no readable structure, which makes the rating plate the only reliable reference. Where the water shows up narrows the cause before any panel comes off. Under the crispers and out of the door is a blocked defrost drain; at the back is the pan or the supply; inside along the seal is condensation from air that should not be getting in.
What you observe on these models
- Water under the crispers and then out of the door — The classic blocked defrost drain. Meltwater backs up in the compartment floor and takes the shortest route out once it has nowhere else to go.
- A wet patch at the back or under the cabinet — The drip pan, the drain outlet, or a supply fitting. It is worth distinguishing before opening anything, because one is meltwater and one is not.
- Ice forming in a sheet on the compartment floor — A drain that has iced over completely. The water freezes where it stands instead of draining, and the sheet grows with every defrost.
- Condensation or ice along the door seal — Warm humid room air arriving where the seal is not closing. The frost pattern marks the leak, which makes it the most self-diagnosing symptom here.
Causes, most likely first on the MS line
- Defrost drain blocked or iced — Ranked first on this roster: it is progressive: the first block produces a small overflow and each defrost after that adds to the ice rather than clearing it.
- Door seal admitting humid air — Ranked second on this roster: a seal that has taken a set lets room air in continuously, that moisture condenses on the coldest surface it reaches, and eventually it runs out at the same place it came in.
- Supply line, filter housing or inlet fitting leaking — It ranks third here because it is the only cause here that can put down more water than the cabinet makes, and because it does real damage while it is ignored.
- A split drain line or damaged liner inside the insulation — Ranked last on this roster: it is the one result that turns a leak into a repair-or-replace decision.
- Body: Where this ranking departs from the brand-generic order is door seal admitting humid air, which moves up on the MS line because this roster is a single cabinet rather than a line, so the order is what that one machine makes likely and not an average taken across several.
Check in this order, and why
- Take the code from the rating plate, not from the shelf label — This roster is recorded as a single catalogue number with no readable structure, so nothing about the code tells you what the cabinet is. The plate is the only reliable reference.
- Find the drain opening in the compartment floor and test it — Pour a small amount of warm water into it. If it backs up rather than draining away, the route is blocked.
- Run the paper test around the whole door perimeter — Anywhere the paper slides out freely is admitting air, and that is where the condensation is forming.
- Close the shut-off and look at every fitting — Check the filter housing, the inlet and the visible run of the line. A fitting wet on top of the cabinet floor is not meltwater.
Before you open anything
Safety
Switch off at the breaker before any panel comes off and treat what is behind it as live until proved otherwise. Deal with the floor before the cabinet: a wet floor beside a plugged-in appliance is a shock risk and a slip risk together. Close the water shut-off before disturbing a fitting, because a line under pressure behind a heavy cabinet is hard to stop once it starts, and get help before moving a full cabinet.

When to call a technician
Call when the leak repeats after a cleared drain, a clean paper test and a levelled cabinet, because that pattern rules out everything an owner can reach. Call immediately if water has reached the supply cord or a socket, and switch the circuit off before touching anything; at that point it has stopped being a nuisance and become a hazard worth treating as one.
