What this means on these models
If a WAP washer has stopped draining since the machine was moved, start at the hose rather than the filter. A hose pushed too far into a standpipe siphons, and one looped wrongly never lets the tub empty at all.
What owners of these models report
- NEAR MISS - a small amount of water always left in the seal — Normal on a front-loading machine; the door seal holds a little water by design.
- The drum drains but the clothes stay soaked — That is a spin problem rather than a drain problem, and it points at balance or the motor.
- A bad smell from the drum between washes — Standing water and trapped debris in the filter housing. It usually accompanies a partial blockage rather than a total one.
- The door will not open after the cycle — Correct behaviour rather than a second fault: the lock holds while there is water above the door line.
- The cycle ends with water standing in the drum — The drain gate was never satisfied, so the programme stopped rather than continuing over water.
What it usually turns out to be
- Coin, clip or button jamming the pump impeller — Second, and often found in the same look as the first: anything small enough to pass the filter seat ends up on the impeller.
- Drain filter blocked — First on this family by a wide margin and by design: the filter is placed to catch debris before the pump, so that is where the debris is.
- Drain hose kinked behind the machine — Common after a move or a floor clean, and it produces a slow drain before it produces no drain at all.
- Pump wiring or control fault — Last, because everything above produces the same standing water for far less money and because this one needs a meter to confirm.
The diagnostic order for these models
- Check the filter housing for a build-up of detergent scum — A partial restriction that builds over months and that explains a slow drain with no obvious object in it.
- Put a tray and towels down and open the drain filter — It is the first thing in the water's path and the designed access point, so it is both the test and, usually, the repair.
- Turn the pump impeller by hand once the filter is out — A jammed impeller is obvious to a finger and invisible to a meter, and this is the moment to feel for it.
- Run a short programme and watch when the drain is attempted — Confirms whether the cycle reaches the drain step at all, which rules the upstream stall in or out.
Power down first
Safety
Unplug the washer or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off, and on a drum machine the motor control board is the last thing to let go of it.

The line between a fix and a call
Call once the owner-side checks are clean, or the moment the fault points at the bearings, the motor or the control board. Those need the machine stripped or a meter on a live circuit, and neither is a kitchen job.
