The short answer for Artt ATUF
The Artt ATUF family answers this differently from the brand as a whole: here a blocked defrost drain or a drain plug left in ranks ahead of a cracked liner or a failed internal drain trough, because of how these models are built and how they are reached. The first checks cost nothing, and three of the four causes listed here can be settled without a meter.
What you observe on these models
- Ice growing in a sheet across the floor of the cabinet — Melt water refreezing where it stands — the signature of a blocked drain on a frost-free cabinet.
- Water appearing only after a power cut or a door left ajar — A one-off thaw, not a fault, though it is worth checking what the contents did.
- Water inside a chest cabinet after a manual defrost
- NEAR MISS — water plus contents that have gone soft — That is melt from a cabinet that has stopped cooling, and the cooling page is the right one. The water is a symptom there.
Causes, most likely first on Artt ATUF
- A blocked defrost drain or a drain plug left in — A frost-free cabinet melts frost on a schedule and must send the water out; a chest cabinet has a drain plug that is meant to be removed for a manual defrost and replaced afterwards. It sits at this point because a frost-free drain ices shut where it leaves the compartment, which is precisely where the melt water then backs up.
- A drain pan that is full, cracked or knocked out of position — It earns this place because it is visible with the lower panel off and needs no test equipment.
- A lid or door seal letting warm air in — Placed at this point because a freezer usually lives in the most humid room in the house, so a marginal seal produces standing water here and only a film elsewhere.
- A cracked liner or a failed internal drain trough — Water arriving from behind the liner, where nothing reachable from the front can catch it. It is here because the tell is a leak that returns after the drain has been genuinely cleared and the seal genuinely tested.
Check in this order, and why
- Find the drain outlet and pour a little warm water into it — Water that does not run through has found the blockage; on a chest cabinet, check the plug is actually in place after a defrost.
- Look at the pan under the compressor with the cabinet pulled out — A pan sitting crooked, cracked or brim-full has been found, and nothing inside the cabinet needs opening.
- Why this order and not another — It follows the ranking, not a generic checklist: on Artt ATUF the first check separates a blocked defrost drain or a drain plug left in from a drain pan that is full, 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
Everything reachable with the cord out is owner work here: the drain, the plug, the gasket, the pan, the levelling and the hose routing. The call begins where the liner does — water appearing from behind it cannot be reached without stripping the compartment, and that is a technician job.
