The answer first
The Artt HD refrigerator family covers a single listing in the roster below, and on that platform the timing of the leak names its cause before anything is opened. A refrigerator leak is nearly always melt that missed its route, and that route is short enough to inspect in a few minutes. Water travels along the cabinet base before it reaches the floor, so where it lands says very little about where it started.
What you observe
- Water under the crisper drawers inside the cabinet — This is defrost melt that could not reach the drain. It is the classic signature of a drain opening that has iced over at the back of the fresh-food compartment.
- Water only after the door has been open a long time — Warm humid air condensing on cold surfaces produces real puddles in humid weather, and it is not a fault in the machine so much as a consequence of how it is being used.
- The seal is damp and the floor at one side is wet — Warm air is being let in and condensing on the frame. A door that does not pull itself shut from half open will do this every humid day.
- NEAR MISS — water appears only when the dishwasher or sink runs — That is a shared waste connection backing up rather than the refrigerator, and no work on the cabinet will change it.
Causes, most likely first on the HD line
- Defrost drain blocked or frozen at its opening — Ranked first here, because every cabinet of this type melts ice on purpose several times a day, and it all goes down one small opening that debris and a slow ice bridge can close, which is why this cause outranks everything else here. This label covers one listing, so there is no variant to rule out first and the order below goes straight at the fault.
- Water supply fitting, filter housing or inlet valve weeping — Second here, because it applies only to machines plumbed for water, but when it does it is the one cause here that runs continuously rather than in step with the defrost cycle, and the volume can be far higher.
- Condensation in humid weather rather than a leak at all — Third here, because it wets the outside of the case and the door frame rather than the inside of the cabinet, which is the distinction that keeps a technician from being called about physics.
- Dispenser line, chute flap or drip tray in the door — Last here, because it is plumbing carried in a moving panel, which is a harder life than any fixed fitting has, and everything it leaks lands at the front where it is noticed.
What to check first, second, third
- Find where the water starts, not where it ends — Dry everything, lay paper towel at the front, at one side and at the back, and wait.
- Empty the lower compartments and look for standing water — Pull the crisper drawers and the freezer baskets right out. Water under the drawers or a sheet of ice below the baskets is direct evidence of a drain that is not carrying melt away.
- Check the level with the doors open and closed — A cabinet that has settled forward sends escaping water to the floor rather than into the pan, and doors that do not swing themselves shut from half open confirm it.
- Pull the machine out and inspect the drain pan — The pan sits above or beside the compressor. Look for a crack, for a pan sitting off its mounts, and for a tube that is discharging beside the pan rather than into it.
Before you open anything
Safety
Water and mains wiring share the machine compartment, so unplug the appliance or switch off its breaker before working at the back — and remember a capacitor can hold a charge after the power is off. A refrigerator is heavy and a wet floor is slippery, so get a second pair of hands before it comes out of its recess and walk it rather than tipping it. Keep hands out of the machine compartment while the machine is plugged in: the condenser fan starts without warning..

When this stops being an owner job
Call straight away for a supply-side leak you cannot isolate at its own valve, because water under pressure behind a heavy cabinet does more damage in an afternoon than the repair will cost. Anything that only costs comfort can wait for a convenient appointment. Anything that has the cabinet warming, or water on a floor that will not dry, should be looked at the same day.
