The short answer
The ARF roster spans several capacity cores rather than one, so the cabinets it covers differ in how far air and meltwater have to travel inside them, and each entry carries a bracketed chassis reference alongside the model code, so the full code and not the family name is what identifies a part. 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
- The floor is wet but the cabinet is dry inside — The water is arriving from behind or below. Look at the pan, the drain outlet and the supply fitting before anything inside.
- 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.
Causes, most likely first on the ARF 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.
- Drip pan cracked, displaced or overflowing — Ranked second on this roster: the pan under the cabinet is where the drain is supposed to deliver, and one knocked out of position during a move puts the water on the floor instead of under the compressor.
- 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 drip pan cracked, which moves up on the ARF line because the roster spans several capacity cores, and a longer cabinet has a longer air path and a longer run to its drain.
Check in this order, and why
- Read the whole code, bracketed chassis reference included — Entries on this roster carry a chassis reference alongside the model code, and the reference is what a part is matched to. Take it from the rating plate before you start, not afterwards.
- 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.
- Look at the pan under the back with the power off — Confirm it is in position, intact and not overflowing. A brimming pan means the cabinet is making more water than it should.
- 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
Owner territory here is wide. The drain, the seal, the level, the pan, the visible supply run and the ice maker are all reachable with no tool and no panel. It ends where the drain route disappears into the insulation, and at any fitting you are not confident re-making.
