The short answer
On the URBD family the usual reason a Criterion refrigerator is leaking or pooling water is supply line or its fitting at the inlet valve. Meltwater causes are owner work; anything fed by the house supply is not, and the first move there is to shut the valve.
What you observe on these models
- Water that returns overnight with nobody using the appliance — A continuous source rather than a cycle-driven one, which points at plumbing.
- A puddle that appeared after a filter change — The one joint the owner operates by hand, and the one most often left proud.
- Damp or beading around the door frame — Humid air meeting a cold surface, which is a sealing problem.
- A puddle on the floor at the front — Either the pan below or condensate running forward instead of to the channel.
- Water under the salad drawers — Meltwater that could not reach the drain, arriving well away from where it formed.
- NEAR MISS — water plus a cabinet that is no longer cold — That combination is a cooling fault with meltwater as a side effect, and that page is the right one.
Causes, most likely first on the URBD family
- Supply line or its fitting at the inlet valve — Ranked first here: a plumbed cabinet has a supply line, a shut-off and a valve, and every joint in that chain is a candidate. A weep rather than a spray is what produces a puddle that appears overnight and never while anyone is watching.
- Door seal letting humid air in — Second: warm humid air meeting cold surfaces condenses, and a door that is not sealing supplies it continuously.
- Blocked defrost drain — Third: meltwater from each defrost has one route out of the cabinet, and that route is a small hole that food debris and ice plug readily.
- Drain pan cracked or off its seat — Fourth: the pan under the appliance is supposed to hold the meltwater until it evaporates.
- Ice maker fill tube or overfill — Fifth: it belongs on the list because the water arrives in the freezer rather than the fridge, which points away from every drain cause above.
- Ice building in the drain trough — Sixth: the trough under the evaporator can ice over even when the drain itself is clear, and once it does, meltwater runs off the front of it instead of into the hole.
Check in this order, and why
- Dry the floor, then look behind the appliance after a few hours — A weep at a fitting shows itself as a returning puddle with the cabinet untouched.
- Close each door on a sheet of paper and pull — A seal that lets the paper slide is supplying humid air continuously.
- Find the drain hole at the base of the evaporator area — A blocked hole and water standing above it is the whole diagnosis.
- Look under the appliance for the shallow pan — Cracked or off its rails, it puts meltwater straight onto the floor.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Leave the door switch wired exactly as it is: it cuts power to the cabinet fan for a reason, and defeating it puts a spinning blade in a space your hand goes into. Anything on the sealed system is licensed work, so if you find oil at the tubing, stop there. Get help before moving the cabinet: it is heavier than it looks and it will pivot on its front feet.

When to call a technician
Once a manual defrost has cleared the drain and the trough and the water still comes back, the remaining causes sit behind a panel or on the plumbing, and both are service work. Shut the supply off first if the puddle is at the back, then call.
