Amana AQ cabinets leak at the defrost drain far more often than anywhere else. The model matrix on this page lists one model number under this family badge. The drain carries debris-laden melt water through the coldest part of the appliance on every cycle, which is exactly the recipe for a tube that silts and then freezes shut.
What you observe
- Water pooling under the crisper drawers — A shallow pool under the salad drawers that returns within a day of being mopped up.
- A sheet of ice on the freezer floor — A hard sheet of ice under the bottom freezer basket, built in layers one defrost cycle at a time.
- Water at the front of the floor, usually after a cycle — A puddle that returns hours after being mopped tracks the defrost cycle rather than the supply.
- Water running down the inside of the door liner — Droplets on the shelves and running down the inside of the door, which is condensation rather than plumbing.
- NEAR MISS — water only in the drain pan at the back — That is the system working. Melt water collecting in the pan and evaporating is normal and needs nothing.
Causes, most likely first on the AQ line
- Supply line, inlet valve or dispenser tubing leaking — First on the AQ line not because it is the likeliest but because it is the only source here that never stops. A pressurised joint is ruled out first on consequence alone.
- Blocked or frozen defrost drain — Second. If the water only appears after the unit has been running, this is almost certainly it.
- Door seal or a door not closing fully — Third because humid room air condensing inside a cabinet looks exactly like a leak and is the appliance doing what physics requires, and the repair is at the gasket rather than the drain.
- Drain pan cracked or off its seat — Last: uncommon, and it presents as water at the rear after the drain has already been proved clear.
The check order on these models
- Close the household water valve and leave it an hour — A leak that stops is supply water; one that continues is melt water, and the two lead in opposite directions.
- Look at the back of the unit for a wet joint or a wet pan — With the water off, any remaining wetness at the rear is the pan or the drain tube rather than a live joint.
- Clear the defrost drain at the freezer floor — With supply excluded, this is where interior water comes from.
- Paper-test the gasket all round both doors — Last, because it explains liner condensation rather than a floor puddle, and it is the slowest to confirm.
Before you open anything
Safety
Unplug the appliance or switch off its breaker and mop up first; a capacitor can hold a charge after the power is off. Clear a frozen drain with warm water and patience rather than a stiff wire — the tubing behind the liner is thin, and turning a blockage into a hole is not a repair anyone can undo.

When to call a technician
The condition is whether the leak stops when the household water is shut off. If it does, a joint is involved and it is worth having done properly. If it does not, it is melt water, and clearing the drain and checking the gasket are reasonable owner work on these models. Damp flooring moves the whole thing to urgent regardless of the source.
