In short
A drain failure on a Bosch WGE washer keeps the door locked, because the machine will not release it over standing water. That makes the fault feel much worse than it is: the lock is working correctly and the water is the only real problem.
Symptoms on this family
- 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 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.
- 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.
Causes, most likely first on this family
- 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.
- 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 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.
- 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.
Check in this order, and why
- 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.
- 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.
- 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.
What to do before you start
Safety
Kill the power first. If the machine needs to come forward, walk it rather than dragging it: these cabinets carry a heavy counterweight at the top and they tip more easily than their weight suggests.

When to stop and book a visit
Book a visit when the same fault returns after a correct repair. A repeat failure on these machines usually means a second fault upstream, and chasing it from the outside costs more weekends than it saves.
