The short answer for the W models
On the AEG W washer models, water that will not leave the machine leads somewhere the brand-generic article does not put first — a jammed pump impeller. The brand-generic ordering opens instead with this: the pump filter behind the plinth. It moves down behind the lead here, because this family is one model rather than a range, so the ranking can be specific where a brand-wide one has to hedge.
What you observe on these models
- The washing comes out heavy and dripping — Drained partially and never spun, which is the same fault seen from the other side.
- The pump can be heard running and nothing leaves — Motor turning, no flow: blockage rather than a dead pump.
- A gurgle from the sink or the standpipe during drain — A shared drain that is struggling rather than a machine that is failing.
- NEAR MISS — it drains fine but will not spin — If the water leaves and the spin does not happen, treat it as a balance or lock question.
Causes, most likely first on the W family
- A jammed pump impeller — A coin or a wire stops the impeller dead while the motor still hums, which is why a running noise does not rule this out. Ranked first on the W models.
- The pump filter behind the plinth — On a European-pattern machine the coin trap is the designed first check and it is behind a flap at the bottom of the cabinet. Second.
- The standpipe, the trap or the shared drain is blocked — Lint and detergent scale narrow a waste pipe over years. Third.
- The pump itself has failed — The only honest evidence for it is silence at the drain phase with power confirmed and the path clear. Last, and that is the point of the order.
- Body: The spine for the W family records a single model code, so there is no variation inside this family to hedge against: what is written here applies to the whole of it. Where this departs from the brand-generic ordering: the cause that moves up on these models is this one — a jammed pump impeller — and the brand-generic lead moves down behind it.
Check in this order on the W models, and why
- Take the plinth off and open the filter flap — First: It is the designed owner check on this pattern of machine and it accounts for most of these faults, so nothing else is worth doing first.
- Listen at the start of the drain phase — Second: A humming pump with no flow is a blockage; silence is power or the pump.
- Open the pump filter and look at what comes out — Third: It answers the most common cause directly, and what you find usually names the fault.
Before you open anything
Safety
Isolate at the breaker and close both valves before a panel or a hose is touched: the capacitor holds a charge past the switch, and the drum and sump hold more water than they look like they do. The door interlock stays as it is — it is what keeps a fast-spinning drum shut, and it holds the door while the water is still hot.

When to call a technician
Call when the filter is clear, the impeller turns by hand, the hose runs straight at the right height, the standpipe takes a jug of water freely, and the machine still holds its water — that puts it at the pump, the sump hose or the level sensing. Call rather than reach in if a glass has broken in the machine, because the fragments go straight to the filter and the impeller. On the W models the line sits where the check stops being one you can make from outside the cabinet. When you book, say that the machine is built in if it is.
