The short answer
On the Arctic Wind ATMB refrigerator line, a water leak is worth working through in a set order: the water supply line, its fitting or the inlet valve first, then a blocked or frozen defrost drain, and only after those does the sealed system enter the picture. That order is written for a line spanning several cabinet sizes and sequenced for how these models are put together, which is where it departs from the brand-generic article.
What you observe
- Water on the floor behind or beside the cabinet, with a dry interior — Dry inside and wet outside means plumbing rather than drainage.
- Water under the crisper drawers or a sheet of ice under them — Water that appears inside the cabinet before it reaches the floor points at the drain, not at a supply line.
- NEAR MISS — the water is warm and the cabinet is not cold — That is a cooling fault and the water is melt from a defrosting freezer. Read the cooling page.
Causes, most likely first on the ATMB line
- The water supply line, its fitting or the inlet valve — Checked first here: on a plumbed cabinet the supply line and its compression fitting run behind the machine where nobody looks, and a slow weep there wets the floor without ever wetting the inside of the cabinet — which is exactly what distinguishes it.
- A blocked or frozen defrost drain — The defrost drain is the most common single source of water inside a refrigerator, and it is reachable without tools.
- Condensation from a door seal that no longer seals — A seal that has lost its grip turns humid room air into water inside the cabinet, which is why the paper test comes early.
- An overflowing or cracked drain pan, or a cabinet tilted forward — A pan or a tilt problem is the quiet explanation for a puddle that keeps coming back after everything else was fixed.
- An internal fill tube, the ice maker fill or the evaporator tray — Last here, and the only cause on this list that is not owner work — a fill tube overshooting, a cracked internal reservoir or a split evaporator tray is reached behind a panel, and on a plumbed cabinet the supply must be isolated before anything is opened.
Check in this order, and why
- Shut the water off, pull the cabinet out and dry every fitting, then watch them — A bead re-forming at a joint within a few minutes names the fitting. Done first because it separates the likeliest causes before any tool is needed.
- Empty the bottom of the cabinet and look for standing water or ice under the drawers — Second: it confirms or dismisses what the first check suggested.
- Close the door on a strip of paper at several points and pull it out — Third, once the two checks above are clean.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel and before mopping around the base — water and live terminals share very little space inside a refrigerator, and a capacitor can hold a charge after the power is off. Shut the water off at the wall valve before touching any fitting. Never clear a frozen drain with a screwdriver or a skewer: the trough is thin and the evaporator sits directly above it.

When to call a technician
Call when the drain has been flushed, the seal passes the paper test, the pan is sound and the water still comes back, because what is left is behind a panel. Call at once if water is reaching a socket or running under a neighbouring appliance.
