The short answer
On an AEG dryer, controls, display or an error indication most often comes back to a latched state after a supply event, with a moisture sensor reading wrongly 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 panel that goes dark and returns
- the machine running only in one mode regardless of what is chosen
- a code or an indicator at the point where the cycle ends
- buttons that respond intermittently
- Not this fault: if there is no heat at all, read the heating page
- Not this fault: if the machine is completely dead, read the start page
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.
- A latched state after a supply event — Why: A full power-down clears more control complaints than any replacement part, and it costs nothing to try.
- A moisture sensor reading wrongly — Why: On a sensing program the machine ends when it thinks the load is dry, so a coated sensor produces short cycles that look like a control fault.
- A door switch that is not reporting closed — Why: The machine will not run a program it cannot prove the door is shut for, and it usually reports that as a control fault.
- A touch panel that has taken moisture or heat — Why: A panel above a heat source suffers, and intermittent response follows long before anything fails outright.
- A child lock holding the panel — Why: It refuses input by design, and the indicator that says so is small and easy to miss.
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 latched state after a supply event — Because: a full power-down clears more control complaints than any replacement part, and it costs nothing to try.
- A moisture sensor reading wrongly — Because: on a sensing program the machine ends when it thinks the load is dry.
- A door switch that is not reporting closed — Because: the machine will not run a program it cannot prove the door is shut for.
Checks you can safely do yourself
- Isolate the appliance before any panel comes off, and stop at the first step that explains the fault.
- Switch the machine off at the breaker for several minutes and restore it. — Tools: nothing — Time estimate: a quarter of an hour
- Run a timed program instead and see whether the machine behaves. — Tools: nothing — Time estimate: one cycle
- Press the door switch by hand and note whether the drum light or the program responds. — Tools: nothing — Time estimate: a few minutes
- Try the panel from cold and note whether it worsens as the machine warms. — 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 code returns immediately after a full power-down, when the door switch has to be replaced, or when the fault is inside the control. Never work on a dryer control with the machine live.

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.
