The short answer
On an AEG dryer, a door or seal problem most often comes back to the door gasket itself, with a worn door catch or strike 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.
- a door that will not stay shut, or that pops open mid-cycle
- a drum seal that is flattened, torn or shedding felt
- clothes catching at the front of the drum
- warm air escaping around the door rather than through the vent
- Not this fault: if the machine will not start at all, read the start page
- Not this fault: if the load is damp, the drying page covers it more usefully
Ranked causes on this platform
- Ranked for an AEG dryer, 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.
- The door gasket itself — Why: A gasket that has hardened lets warm humid air out at the door, which shows as a damp door frame and a longer cycle.
- A worn door catch or strike — Why: A catch that no longer holds under tumbling vibration lets the door open mid-cycle and stops the machine.
- A worn drum felt seal — Why: The felt seals the drum to the bulkhead, so when it wears the machine loses air, loses drying and grinds at the same time.
- Overloading catching the load at the door — Why: A packed drum pushes clothing into the door line, damaging the seal and jamming the catch.
- A lint path that is bypassing the filter — Why: Lint at the door edge means air is leaving where it should not, which is a seal problem showing itself as a mess.
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.
- The door gasket itself — Because: a gasket that has hardened lets warm humid air out at the door.
- A worn door catch or strike — Because: a catch that no longer holds under tumbling vibration lets the door open mid-cycle and stops the machine.
- A worn drum felt seal — Because: the felt seals the drum to the bulkhead, so when it wears the machine loses air.
Checks you can safely do yourself
- Isolate the appliance before any panel comes off, and stop at the first step that explains the fault.
- Feel round the closed door during a cycle for escaping warm air. — Tools: nothing — Time estimate: a few minutes
- Close the door and pull; it should hold firmly rather than springing. — Tools: a screwdriver — Time estimate: a quarter of an hour
- Look at the felt all the way round the front and rear of the drum for thin or missing sections. — Tools: a torch — Time estimate: a quarter of an hour
- Reduce the load and check whether the door still holds. — Tools: nothing — Time estimate: one cycle
- 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. Clear lint from the filter, the housing and the duct: accumulated lint around a heat source is the recognised hazard of this appliance class. Never run the machine with a panel off or the door interlock defeated, and never vent it into the room.
When to call a technician
Call a technician when the drum felt has to be replaced, when the door has dropped on its hinge, or when the catch will not hold with the strike correctly set. A door that opens during a cycle should stop the machine being used.

What this page does not cover
This page is generalized across every AEG dryer 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.
