The short answer
On an AEG washing machine, water left in the machine most often comes back to a pump filter behind a plinth flap that has never been opened, with a blocked pump filter close behind. The maintenance items these machines actually have — the pump filter, the drain path, the sensors and the condenser on a heat-pump dryer — outrank component failure on a machine of this generation. That puts the first move in your hands rather than a technician’s: work the checks below in order and stop at the first one that explains what you are seeing.
What you are seeing
- What this fault looks like, and which observations point somewhere else.
- the machine refusing to spin, which is usually a drain fault rather than a spin fault
- water standing in the drum at the end of the cycle
- a drain that runs and then stops with the level unchanged
- the machine humming during the drain without moving water
- Not this fault: if the machine stops rather than finishing wet, read the cycle page
Ranked causes on this platform
- Ranked for an AEG washing machine, which runs a sensor-driven controller that reports a fault code on the display. No measured frequency exists for this address, so the order is platform judgement rather than a share.
- A pump filter behind a plinth flap that has never been opened — Why: It is designed as owner maintenance and it is almost never done, so the first drain fault on these machines is usually the first filter clean.
- A blocked pump filter — Why: Everything the wash releases collects here, and it is the first place to look on any drain complaint.
- A drain hose at the wrong height — Why: Too high and the pump cannot lift the water; too low and the machine siphons out as fast as it fills.
- A jammed or worn drain pump — Why: Wire, grit and buttons reach the impeller and stop it, so the pump hums without moving water.
- A kinked or crushed drain hose — Why: A hose squashed behind the machine at installation produces a drain fault that appears the day the machine is pushed back.
What to check, in order
- The order follows the ranking above: most likely and cheapest first, nothing needing a meter until everything else is eliminated.
- A pump filter behind a plinth flap that has never been opened — Because: it is designed as owner maintenance and it is almost never done.
- A blocked pump filter — Because: everything the wash releases collects here, and it is the first place to look on any drain complaint.
- A drain hose at the wrong height — Because: too high and the pump cannot lift the water.
Checks you can safely do yourself
- Isolate the appliance before any panel comes off, and stop at the first step that explains the fault.
- Open the plinth flap over a shallow bowl and clear the filter completely. — Tools: a bowl, towels and gloves — Time estimate: allow half an hour
- Isolate the machine, open the filter over a shallow bowl and clear it completely. — Tools: a bowl, towels and gloves — Time estimate: allow half an hour
- Check the hose height against the range the installation instructions give and whether it is pushed too far into the standpipe. — Tools: nothing — Time estimate: a quarter of an hour
- With the filter out, reach the impeller and check it turns freely. — Tools: a torch and gloves — Time estimate: allow half an hour
- Stop condition: Stop there: the next step means metering live terminals or opening a sealed system.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel, because a capacitor can hold a charge after the power is off. Drain the machine before opening a filter or a pump, and expect more water than you think; keep the circuit off while you do it. Never defeat the door or lid interlock. It stops the drum before you can reach it, and a spinning drum does not stop for a hand. A machine full of water is extremely heavy — empty it before it is moved or tipped.
When to call a technician
Call a technician when the filter and hose are clear and the pump still will not move water, when the pump has to be reached from under the machine, or when the waste line backs up into the room. Do not leave a full drum standing for days.

What this page does not cover
This page is generalized across every AEG washing machine family and model number: no family fault list, no model parts list, and no measured figure from the program warehouse. Where a family- or model-specific page exists it goes deeper, and it should be preferred over this one.
