The short answer for Artt ATTM
The Artt ATTM family answers this differently from the brand as a whole: here door seals and a cabinet out of level ranks ahead of a cracked liner, a failed drain trough or a sealed-system fault, because of how these models are built and how they are reached. Of the four causes ranked below, three are owner work and the remainder need a technician.
What you observe on these models
- A slow drip at the back of the cabinet near the floor — The drain pan or the supply connection, both reachable with the cabinet pulled out.
- A stain or swelling on the floor in front of the cabinet — Evidence the leak has been running much longer than it has been noticed.
- A puddle on the floor in front of the cabinet
- A damp patch that appears only in hot weather or after a big shop
- Water that appears only after a big shop or a party
- NEAR MISS — the only water is around the ice maker and the bin — If the maker is overflowing or has stopped, its own page covers the fill valve and the fill tube in full.
Causes, most likely first on Artt ATTM
- Door seals and a cabinet out of level — Warm humid air leaking in condenses on the coldest surface it can find, and on a humid day that produces real water, not a mist. Placed at this point because a door that hangs out of square seals along three edges and leaks along one, which is invisible until you test it.
- The water supply line, its stop or the connection at the cabinet — It is here because it is reachable and visible from behind, and it is the check to do first if the water is outside rather than inside.
- A blocked defrost drain — Ranked here because it is the cause behind most interior water on a cabinet that is otherwise cooling properly, and it is owner-clearable.
- A cracked liner, a failed drain trough or a sealed-system fault — Water arriving from a split trough behind the interior panel, or a leak whose real cause is ice that should never have formed. It sits at this point because a trough that has cracked puts melt water behind the liner where nothing an owner can reach will catch it.
Check in this order, and why
- Test the seals with a sheet of paper and check the cabinet for rock — Paper that slides out freely anywhere has found the air leak that is making the water.
- Dry the connection at the back and watch it for a while — A fitting that re-wets is the leak. Nothing inside the cabinet needs looking at until that is ruled out.
- Find the drain hole at the base of the evaporator or the rear of the compartment
- Why this order and not another — It follows the ranking, not a generic checklist: on Artt ATTM the first check separates door seals and a cabinet out of level from the water supply line, and access decides the rest — what this family puts behind which panel is why the cheap check comes first.
Power off first, and what not to defeat
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. On a cold cabinet the parts that bite are behind the lower rear access panel, where the start relay and the run capacitor live, and behind the interior rear panel, where a defrost heater sits in the airflow.

When to call a technician
Call once the drain has been flushed clear, the seals have been tested, the pan has been checked and the supply connection has been dried and watched — and the water still returns. What remains is behind the liner. Call immediately if water is reaching an electrical connection or spreading under a floor, because that damage compounds every day.
