What this means on these models
An Amana H that will not drain is blocked far more often than it is broken. The matrix on this page is the definitive list for this family: seven model numbers. The pump filter, the drain hose and the standpipe account for most cases, and all three are checkable before anything is dismantled — which is why the pump itself ranks below them here.
What you observe
- The cycle ends with water still in the drum — The machine believes it has finished; the water says otherwise, which usually means the drain ran and achieved nothing.
- 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.
- Silence where the drain stage should be — Nothing audible where the drain should be, which moves the diagnosis to the lid switch, the level sensing or the control.
- 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 — Water that leaves normally with a drum that will not turn is a drive fault, and nothing on this page applies.
What it usually is, in order
- Drain hose kinked, too high or pushed too far down the standpipe — Ranked first on the H line because seven model numbers is enough of a span that two units with the same badge can differ in what is fitted — the hose is the part of the drain path most often disturbed and least often inspected, and it is visible without tools.
- Pump filter full — Second because the filter is the designed trap and the commonest blockage once the hose geometry is right.
- Foreign object jammed in the pump impeller — Third: the pump hums and nothing moves, and the object is usually reachable through the filter housing.
- Pump motor, control or pressure sensing failure — Last, and the only group here that is not cleared by hand.
The check order on these models
- Pull the machine out and look at the full hose run — First because the hose is disturbed every time the appliance moves and a kink behind a foot is invisible from the front.
- Check how deep the hose sits in the standpipe — Pushed too far down it siphons or blocks, which is why a maximum insertion depth is specified.
- Open the pump filter and clear it — Third, and the commonest blockage once the geometry is right. Have a tray ready — the housing holds water.
- Listen at the start of a drain for hum, strain or silence — That separates a straining pump from one that is never asked to run.
Before any panel comes off
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.

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