The short answer
For a VPC unit: two systems can leak and they produce different puddles. Knowing which one you have before anything is dismantled is most of the diagnosis, and it takes one look with a flashlight. That is the same list the brand-generic page carries, in a different order.
What an owner actually sees on a VPC unit
- A damp patch on the wall or floor behind the appliance — That is the supply side, not the defrost side, and it is a fitting or a line. On these VPC models it is the observation that decides the order.
- The drip tray under the unit is dry when it should not be — Melt water is going somewhere else, and where it is going is the leak.
- A sour smell from under the crispers — Water that has stood for a while, which dates the leak as older than the puddle you just found.
- NEAR MISS: no ice and no water at the dispenser — That is a supply fault rather than a leak, and it is covered on the ice-production page.
Causes in likelihood order on the VPC line
- A defrost drain blocked with ice or debris — Ranked first by a wide margin. Every automatic-defrost refrigerator makes melt water on a cycle, and the only path out is a narrow drain that clogs with food fragments and then freezes solid. On the VPC models this stays at the top because nothing about the platform makes it less likely.
- A cracked or overflowing drip tray — Second. The tray under the unit is supposed to evaporate what the drain delivers; cracked or overfilled, it delivers it to the floor instead.
- A failed water inlet valve — A valve that no longer closes fully drips continuously and quietly. It shows as a damp back wall and a puddle that returns however often it is mopped.
- A cracked water reservoir or dispenser line inside the door — Last, because it is the least common. It shows as water in the door shelves rather than at the back.
Where to start, and why
- Pull the crisper drawers out and look at the liner floor — Standing water there is the blocked-drain signature and it is visible in seconds. The VPC layout is the reason it comes first here.
- Slide the unit out and check the drip tray — A dry tray on a leaking appliance proves the water is not getting there; a cracked one proves where it goes instead.
- Note how often the water appears — Every few days is the defrost cycle; continuously is the supply side. One observation, two very different lists.
- Ask whether there has been a power cut or a door left open — A one-off melt load explains a one-off puddle and needs no repair at all.
Isolate it first
Safety
Unplug it, dry the floor, and shut the water off at the valve. Stored charge outlives the switch, so leave the appliance isolated for the whole job. Do not chip at ice with a knife or a screwdriver: the liner and the drain tube behind it puncture easily.

When to call a technician
Once the free checks are clean, the remaining candidates are the inlet valve, the drain heater and anything behind the evaporator panel. Call then, and call urgently if you can smell anything hot or see a damp electrical connection.
