The short answer
On the ATW models this complaint is most often a drain hose kinked or pushed too far into the standpipe rather than anything deeper. This line is a close pair of models rather than a spread, so the build is effectively uniform and the seal-and-fit causes come forward. The order below is settled by how this line is built, not by what is true of the brand as a whole.
What you observe
- The machine drains but takes far longer than it used to — A partial blockage rather than a complete one, and it will finish becoming complete.
- Water backs up out of the standpipe — That points away from the machine and at the house drain.
- Foam is standing above the water in the drum — Suds prevent the pump priming, and the machine waits.
- NEAR MISS — the drum is empty and the cycle still will not advance — Then the level sensing is the question, and the drain has already done its job.
Causes, most likely first on the ATW line
- A drain hose kinked or pushed too far into the standpipe — Ranked first here — it is free to correct and because it is the commonest fault on a machine that has recently been moved.
- A pump filter or coin trap packed solid — Second here — it is where everything the drum lets through ends up, and it is the one part of the drain circuit an owner can open.
- A drain pump that no longer moves water — Third here — it is the component most exposed to what the filter misses.
- A lint bridge in the sump hose — Fourth here — it sits between the drum and the pump and it builds slowly on a machine that washes bedding and towels.
- Body: Two closely related models means what holds for one holds for the other, which is why the order below is stated without a hedge. Against a ranking that ignored how these are built, a drain hose kinked or pushed too far into the standpipe moves up and a pump filter or coin trap packed solid moves down — that is the whole departure.
Check in this order, and why
- Pull the machine out and follow the drain hose along its whole run — A tight bend behind the machine, or a hose driven a foot down a standpipe, will do it.
- Open the filter door at the bottom front and empty the trap — Do it with a tray and towels down and the taps shut.
- Listen at the drain step for whether the pump runs at all — A pump you can hear that moves nothing is different from a pump you cannot hear.
- Note whether the machine drains very slowly rather than not at all — A partial blockage drains, just far too slowly for the cycle to accept.
- Body: Two closely related models share a layout, so a check that works on one works on the other and the order below does not change between them. Each check answers the cause above it, in the same order, so a clean result moves you down the list rather than sideways.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Shut both taps and lay towels and a shallow tray before opening a pump filter: a stalled machine may hold a full drum, and it comes out faster than a bowl will take.

When to call a technician
Call when the filter is clear, the hose run is straight, the standpipe drains and the machine still will not empty — at that point the pump or the sump hose is the answer, and both need the machine opened. Call at once if water is reaching a socket or an extension lead.
