The short answer
Most drain complaints on the WGG line are cleared with a tray, a towel and ten minutes at the filter door. The point of the ranking below is to stop owners buying a pump for a fault that a coin caused.
What this looks like from the kitchen
- 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 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.
- The cycle ends with water standing in the drum — The drain gate was never satisfied, so the programme stopped rather than continuing over water.
- 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.
- 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.
Likeliest causes first
- 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.
- 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.
- 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 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.
Check in this order, and why
- 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.
- 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.
- 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.
- 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.
Before any panel comes off
Safety
Disconnect power and close the inlet taps before starting. A machine that has stopped mid-cycle may still be holding a tub full of water, and that water leaves through the drain filter whether you are ready for it or not.

The line between a fix and a call
Stop and call if the machine has already been part-dismantled and will not go back to a known state. A half-assembled drum machine is the one situation where a service call actually gets cheaper by being made earlier.
