The short answer for these models
When the AERC line leaves water on the floor, the first question is not what broke but where the water was before it was on the floor. The table on this page covers a small group of model numbers in the same line. The drain path answers it more often than any component.
What you observe
- 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.
- A sheet of ice under the drawers rather than water — The same blockage in a colder cabinet. It freezes where it collects, and it will thaw into a floor leak the moment the machine is switched off.
- Damp only in the bottom drawer, nowhere else — Condensation collecting at the coldest, least ventilated point in the cabinet rather than a drain fault.
- Damp or a stain at the rear wall behind the cabinet — A supply line weeping at a fitting. Small, slow and the most damaging of all the leaks on this list because it goes unnoticed.
- NEAR MISS — water only in the drip tray at the back, with a dry floor — That is normal. Every refrigerator evaporates its melt water from a tray; a wet tray is the machine working.
Ranked causes for these models
- Blocked defrost drain — First on the AERC line, and it is not close. Every cycle sends melt water down a narrow drain, and food debris, mould or an ice plug at the exit all stop it. The water then backs up inside the cabinet and appears under the drawers rather than at the drain.
- 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.
- Door seal and condensation — Third. Air leaking past a seal brings moisture, and moisture is what the drain has to remove. A leaking seal therefore both creates extra water and overloads the path that carries it away.
- 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, and often self-inflicted during a previous repair attempt, which is why clearing a drain should be done with warm water and a soft line, not a screwdriver.
What to check first, and why that order
- 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.
- Flush the drain even if the seal was the fault — The extra moisture a leaking seal makes has already been through the drain, so it is usually part-blocked by the time the leak is noticed.
- Check the back only if the paper there is wet — Keeps the plumbing work for the case that actually calls for it.
Before you open anything
Safety
Isolate the cabinet at the plug or the breaker before working, especially with water on the floor. 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. If the leak came with a warm cabinet, judge the food by temperature rather than by the puddle: a refrigerator holds food safely at 40 °F (4 °C) or below and a freezer at 0 °F (−18 °C) or below.

The line between an owner fix and a service call
Call when the drain has been flushed, the cabinet is level, the pan is in place and water still appears. That combination points above the evaporator cover, which is a service job. On the AERC line a technician will also check the defrost operation itself, because a drain that blocks repeatedly is usually a defrost fault wearing a drainage costume.
