Tumble Dryer
F09
The F09 error code on an AEG tumble dryer indicates a fault with the motor or motor control circuit — it’s one of the more serious error codes, but there are a few checks you can do before calling an engineer.
What does this error mean?
F09 signals that the dryer’s control board has detected an abnormal condition in the drive motor or its associated wiring and control circuitry. The machine cuts out to protect itself from further damage. In plain terms: the drum isn’t spinning correctly, or the electronics that tell the motor to spin have developed a fault.

🔍 Likely causes
🛠️ Step-by-step fix
Power off and unplug the dryer completely, then leave it for 10 minutes. Plug back in and run a short cycle — a temporary voltage spike can occasionally trigger F09 and a reset clears it.
Check the drum rotates freely by opening the door and manually turning it. If it feels stiff, grinds, or won’t move at all, the bearings or belt are likely the issue — do not run the machine.
Remove the back panel (two to four screws, no specialist tools needed) and visually inspect the drive belt. A snapped belt is easy to spot — it will be hanging loose or missing entirely. Replacement belts for AEG dryers cost £10–£20 online and are a straightforward DIY job.
While the back panel is off, inspect the visible wiring connections to the motor for any that are loose, burnt, or corroded. Gently press connectors back into place if they’ve worked loose — do not attempt to repair burnt wiring yourself.
If the belt is intact, the drum spins freely, and wiring looks fine, the fault is likely the motor, capacitor, or PCB — stop here and call a qualified appliance engineer, as these components involve live electrical parts.
When booking a repair, tell the engineer you have an F09 fault code — this helps them bring the likely parts (motor, capacitor, or PCB) and avoids a wasted diagnostic visit.
📞 When to call a professional
If the reset doesn’t clear the code and the drive belt is intact, call a qualified appliance engineer — motor, capacitor, and PCB replacements involve opening live electrical components and are not safe DIY tasks. Tell the engineer it’s an F09 motor fault on an AEG condenser or heat pump dryer, and give them the full model number (found inside the door frame) so they can source parts in advance.
⚖️ Repair or replace?
A professional motor or PCB repair on an AEG tumble dryer typically costs £100–£200 including parts and labour in the UK. If your dryer is under 6 years old, repair is almost always worth it — AEG machines are mid-to-premium quality and parts are widely available. If it’s over 8–10 years old and the motor has failed, a new heat pump dryer (£400–£700) may be more cost-effective long-term given improved energy efficiency.
