Tumble Dryer
F10
The F10 error code on an AEG tumble dryer indicates a problem with the NTC temperature sensor — the component that monitors heat inside the drum. It’s a moderately serious fault that will stop your dryer from running, but in many cases it’s fixable at home.
What does this error mean?
F10 signals that the control board has detected an abnormal reading from the NTC (Negative Temperature Coefficient) thermistor, which continuously measures drum temperature during a cycle. Either the sensor is reading a temperature that’s impossibly high or low, or it has lost its connection to the board entirely. The dryer shuts down as a safety precaution to prevent overheating or fire.

🔍 Likely causes
🛠️ Step-by-step fix
Reset the dryer: Switch it off at the wall, leave it unplugged for 10 minutes, then plug back in and run a short cycle. A one-off software glitch can trigger F10 and a reset clears it.
Clean the lint filter thoroughly: Remove the filter (usually inside the door aperture), clear all fluff, and rinse it under the tap if it looks clogged. A blocked filter is the single most common cause of heat faults on AEG dryers.
Clean the condenser unit (condenser models only): Open the condenser flap at the bottom front of the machine, remove the condenser cassette, and rinse it under a cold tap until water runs clear. Refit securely and allow to dry slightly before running.
Check the exhaust duct (vented models only): Pull the dryer away from the wall and inspect the full length of the venting hose. Straighten any kinks, clear any blockages, and ensure the external vent flap opens freely.
Inspect the NTC sensor wiring: If you’re comfortable doing so, unplug the machine, remove the back panel (two to four screws), and check that the NTC sensor connector — a small plug near the heater housing — is firmly seated and shows no signs of burning or corrosion. Reseat it if loose. Do NOT touch the heater element or capacitor.
Replace the NTC sensor: AEG NTC thermistors are widely available online for £10–£25. Match the part number from your model plate (inside the door). Unplug the old sensor, plug in the new one, refit the panel, and test. If the error persists after sensor replacement, stop DIY and call an engineer.
📞 When to call a professional
If F10 returns after you’ve cleaned all filters, checked the duct, and replaced the NTC sensor, the fault is most likely a failed PCB — and board replacement or diagnosis requires a qualified appliance engineer. Call a professional and tell them: ‘My AEG tumble dryer is showing F10, the NTC sensor has been replaced but the fault persists.’ This helps them prepare the correct parts before arrival.
⚖️ Repair or replace?
A professional repair for an F10 fault — typically NTC sensor or PCB replacement including labour — will cost £80–£150 in the UK. If your AEG dryer is under 5 years old, repair is almost always worth it; AEG machines are mid-to-premium quality and built to last 10–15 years. If it’s over 8 years old and the PCB needs replacing (£100+ in parts alone), a new dryer from £300 upwards is likely the smarter investment.
