The short answer
The ARM 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 it lists two naming generations side by side, so cabinets of noticeably different ages share this page. Water at a refrigerator in this roster comes from one of two places: meltwater that never reached its drain, or supply water that escaped a fitting. Telling them apart is the whole diagnosis, and the volume usually does it for you.
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 ARM line
- Defrost drain blocked or iced — Ranked first on this roster: the drain is the narrowest part of the water route and it sits in the coldest part of the cabinet, so once an ice plug or a debris plug forms there every later defrost backs up into the compartment.
- Supply line, filter housing or inlet fitting leaking — It ranks second 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.
- Drip pan cracked, displaced or overflowing — Ranked third on this roster: a pan that is simply brimming is reporting a problem upstream, so finding it full is a clue rather than a conclusion.
- A split drain line or damaged liner inside the insulation — Ranked last on this roster: a drain line that has split where it passes through the insulation is the least likely outcome here and the only one that cannot be reached without dismantling.
- Body: The ranking here keeps the brand-generic order, and what the ARM line changes is the order of the checks beneath it: 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
- Establish which generation of this roster you have — Two naming generations are listed together here, so cabinets of noticeably different ages share this page. Which one you own changes what a worn part is likely to be.
- 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.
- 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.
- 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.
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.
