The short answer
An Amana ATW that leaves water in the drum has a restriction, not a failure, in the great majority of cases. The matrix on this page is the definitive list for this family: two model numbers. The path from the tub to the standpipe has four points on it, and the first two are reached through a single opening at the front of the machine.
What the owner reports
- The cycle ends with water still in the drum — A completed cycle over a full drum means the pump was asked to run and the water did not leave.
- The pump hums but no water moves — Hum without flow means the motor is energised and the path is closed — the object is usually in the filter.
- Water drains slowly rather than not at all — A drum that empties eventually but takes several times as long as it used to.
- The machine stops mid-cycle and will not advance — A cycle that hangs at the same point every time is waiting for a level change that never comes.
- Water backs up out of the standpipe — Water rising out of the standpipe onto the floor, which is the household drain rather than the machine.
- NEAR MISS — the drum will not spin but the water does leave — If the water goes and the drum stays still, the drain path is fine and the fault is mechanical.
What it usually is, in order
- Object jammed in the pump impeller — First on the ATW line when the pump hums without moving water, because a motor loaded against a stalled impeller is the most specific symptom on this list.
- Pump filter blocked — Second: the same housing, and it is cleared in the same operation, so the two are always checked together.
- Drain hose or standpipe restricted — Third because the path outside the machine explains a slow drain better than a complete failure, and it needs the cabinet moved.
- Control, lid switch or pressure sensor not calling for drain — Fourth because a drain that is never called for is an electrical diagnosis rather than a plumbing one, and it follows when everything mechanical checks out.
The check order on these models
- Start a drain and listen to the first second — Hum means a jam, strain means a restriction, silence means the pump was never called.
- Open the filter housing and turn the impeller by hand — A jammed impeller is confirmed and usually cleared in the same operation.
- Clear the filter completely and refit it squarely — A filter refitted crooked leaks, so it is worth doing carefully rather than quickly.
- Check the hose run and the standpipe — Check the hose run and the standpipe last, once the pump housing is known to be clear.
Safety first
Safety
Unplug the machine or switch off its breaker before opening the filter or any panel — a capacitor can hold a charge after the power is off. The filter housing holds standing water: put a shallow tray and towels down first, and open it slowly. If the drum is full, bail it down before opening anything, and never open a front-loading door against a full drum.

The service-call line
Book a technician once the drain path is proven clear end to end and the drum still holds water. On the ATW line the practical boundary is the pump housing: everything reachable through the filter opening is owner work, and everything behind the cabinet is not.
