The short answer
Water at or under the URBC line almost always comes from one of three places: the defrost drain, condensation from air leaking past a door, or a supply connection on a plumbed model. The table on this page covers a small group of model numbers in the same line. Where the water appears tells you which, and that is the whole of the first step.
What you observe
- Beads of water on the inner walls or the ceiling of the cabinet — Condensation, not a leak. Warm damp air is getting in, usually past a door seal or through a door left ajar.
- Water on the floor at the front — It has run forward along the cabinet base. On these models that usually means the drain tray or the drain path rather than a supply connection.
- The floor is wet only after the cabinet is moved — A drain pan that has been carrying water all along, tipped when the machine was pulled out.
- Water only after a hot or humid day — Condensation again, and the machine is coping rather than failing — but a drain that is marginal will overflow on exactly these days.
- NEAR MISS — the cabinet is also warm and the freezer is soft — Then the water is melting food, and this is a cooling failure. Use the cooling page for this family first.
What to suspect, in order, on this family
- Blocked defrost drain — Ranked first because the drain is the only part of a refrigerator that is designed to carry water and is not designed to be cleaned. On cabinets of this build it is a short path with at least one bend, which is exactly where a plug forms.
- Drain pan, tube exit and levelling — Second, and it is the cause that explains water on the floor with a dry interior. The drain worked; what happened afterwards did not.
- Humid air getting in past a seal — Third. It is the cause behind the seasonal version of this complaint, and it makes any marginal drain overflow on a humid day.
- Water supply connection on plumbed models — Fourth, and it belongs on the list because it is the most expensive leak to ignore. A fitting that weeps behind the cabinet does its damage to the floor and the wall long before anyone sees a drop.
- Cracked or displaced internal parts — Last. Physical damage is uncommon and usually has a history — a cabinet that was moved, a panel that was forced, a drain channel prised at with a tool while clearing it.
What to check first, and why that order
- Dry everything and put paper down — A dry start with paper under the front and the back turns an argument about where the water comes from into an observation.
- Look at the inner walls and the door frame — Beads and damp mean condensation; a puddle with dry walls means drainage or supply.
- Test the door seal along its whole length — Close the door on a sheet of paper and pull at several points. Any point with no grip is a corner that is feeding moisture in.
- Check the back only if the paper there is wet — Keeps the plumbing work for the case that actually calls for it.
Before any panel comes off
Safety
Power off first — a capacitor can hold a charge after the power is off — and water off before any connection is opened. Warm water, not boiling, for clearing a drain; boiling water deforms the channel. If the water has reached an outlet or a power strip, leave the breaker off until everything is dry. Water alone does not spoil food, but a drain that has been blocked for weeks is not clean. Discard anything that has been sitting in the pooled water and clean the base before reloading.

The line between an owner fix and a service call
Call if the leak is at a supply fitting and does not stop when the valve is closed and reopened, or if water has reached the floor structure. On the URBC line clearing a drain, adjusting feet and reseating a pan are owner work; anything that needs the evaporator cover off, or a plumbing joint remade, is not. Call the same day for a leak behind the cabinet, because that one is quietly expensive.
