The short answer
What you are seeing on a Supreme refrigerator most often comes back to an inlet valve that no longer closes fully, with a cracked, displaced or overfull drain pan behind it. Work the order below rather than the price list: the cheap causes here are also the common ones.
What you are seeing
- Water standing under the crisper drawers — A classic signature. Water that should have gone down the defrost drain has backed up into the cabinet instead.
- Ice building on the freezer floor under the food — Meltwater freezing where it lands because the drain below it is closed.
- NEAR MISS: the unit is also not cooling — Cooling comes first. The water is downstream of that fault, not a separate one.
Causes ranked for this brand, likeliest first
- An inlet valve that no longer closes fully — A valve holding partly open passes a trickle continuously, and the water appears at the back rather than at the front. First here, for a reason specific to Supreme: the valves and the pump are the lowest-cost parts in this build, so they set the fault pattern.
- A cracked, displaced or overfull drain pan — The pan under the unit is meant to evaporate what the drain delivers. Cracked or knocked out of place, it delivers it to the floor. Second, because a compact unit is carried in and set down, never really installed, and nobody re-checks it once it is loaded.
- A door gasket letting humid room air in — Warm air meeting cold surfaces condenses. A gap at the seal produces water continuously and looks exactly like a leak. Third, once the two above are clean: the gasket compound on a value build hardens sooner, so the seal is live well before the machine is old.
- A blocked defrost drain — Every defrost makes meltwater that must reach the pan underneath. Blocked, it backs up into the cabinet and finds the floor. Bottom of the list on purpose: the drain path is short and narrow on this build, so it blocks with less debris than a wider one needs.
What to check first, second and third
- Shut the supply at the tap for a day and see whether the water stops — A free test that rules the whole supply side in or out.
- Pull the unit out and look at the pan under the compressor — A pan out of its seat is visible in seconds and free to fix.
- Run the paper test around both doors — It distinguishes water that is condensing from water that is escaping.
What an owner can safely check
- Shut the water supply off at the tap for a day — No water afterwards means the fault is on the supply side, and that is a part, not a clean.
About 10 min
- Pull the unit forward and check the drain pan is seated, whole and not overflowing — Look for a crack at the corners. An overfull pan on a cool day is normal, a cracked one never is.
Tools: a torchAbout 20 min
- Test the gaskets with a sheet of paper around both doors, then wash the seal and the frame — Sticky residue holds a gasket open more often than perished rubber does.
Tools: a sheet of paper, warm soapy waterAbout 15 min
- STOP HERE if the next step means a meter on the inlet valve terminals — Testing a valve coil with the machine live is where an owner check ends and a service call begins.

Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Get help before pulling the cabinet out: a loaded unit runs away from you on a hard floor and the supply line behind it tears easily. Never open sealed-system tubing.
Where the owner fix ends
Call when the drain will not clear with warm water, when the pan is cracked, or when water keeps arriving after the supply has been off for a day. Call the same day for water near the power cord or a socket: that is not something to leave running while you work through a list.

This page is about the Supreme refrigerator as a class, not one family or model line. Where a family-specific page exists for your unit it is linked below and it is the more precise answer. Not here on purpose: drain routing diagrams, valve part numbers and heater specifications, which differ between families.
