Dispenser
A dispenser leak often hides behind the fridge, not in the door.
The door tray is what people see. The failure is often the supply, a tank, or a fitting at the back. Treat it like any other small-diameter water line.
Stop using the dispenser and the ice maker.
They usually share a supply. One shutoff should quiet both.
Do not keep filling glasses to ‘see if it stopped’.
Each test adds water to a cavity you cannot see.
Photograph the back once it is safe to pull.
A split tube is a useful record for the manager and the insurer.
Questions people ask
Can a dispenser leak without a wet kitchen floor?
Yes. Water can follow the slab into the suite below.
Is filtered-water equipment different?
Aftermarket filters add fittings. More fittings mean more leak points. Isolate them the same way.
