Tumble Dryer
F10
The F10 error code on an Indesit tumble dryer signals a problem with the NTC temperature sensor — the component that monitors heat inside the drum. It’s a moderately serious fault: the dryer will stop running to prevent overheating, but in many cases it’s a DIY-fixable issue.
What does this error mean?
F10 tells you the dryer’s NTC (Negative Temperature Coefficient) thermistor has either failed or is sending readings outside the expected range. The control board interprets this as a temperature monitoring failure and cuts the cycle as a safety precaution. This doesn’t automatically mean the sensor itself is broken — a blocked airflow path can cause abnormal temperature readings that trigger the same code.

🔍 Likely causes
🛠️ Step-by-step fix
Power off and unplug the dryer from the mains — never work on it while connected to electricity.
Remove and clean the lint filter thoroughly. If it hasn’t been cleaned recently, this alone may resolve the F10. Rinse it under a tap, let it dry fully, and refit it.
On condenser models, locate the condenser drawer (usually at the bottom-front of the machine), remove it, and rinse it under running water until all fluff is cleared. Refit securely.
On vented models, disconnect the exhaust hose from the back of the dryer and check for blockages or kinks along its full length. Clear any obstructions and ensure the external vent flap opens freely.
Plug the dryer back in and run a short cycle to see if the F10 clears. If the error returns immediately, the NTC sensor itself is likely faulty and needs replacing.
If you’re comfortable with basic appliance repair, the NTC thermistor can be accessed by removing the back panel. Test it with a multimeter — at room temperature it should read approximately 10,000–50,000 ohms depending on your model. A reading of zero or infinite resistance confirms a failed sensor. Replacement NTC sensors for Indesit dryers cost £10–£25 online. If you are not confident working inside the appliance, stop here and call an engineer.
📞 When to call a professional
If cleaning the filter and condenser doesn’t clear the F10, and you’re not comfortable using a multimeter or removing internal panels, call a qualified appliance repair engineer. Tell them: ‘My Indesit tumble dryer is showing an F10 error code — I suspect a faulty NTC temperature sensor.’ Also call a professional if the dryer was overheating, emitting a burning smell, or tripping the household circuit before the error appeared, as these symptoms suggest a more serious underlying fault.
⚖️ Repair or replace?
A professional repair for an F10 fault — covering the call-out, diagnosis, and NTC sensor replacement — typically costs £80–£130 in the UK. If your dryer is under 5 years old and was mid-range or above (£300+), repair is almost always worth it. If the machine is over 8 years old or was a budget model under £250, weigh the repair cost against a new dryer, as other components may be approaching end of life.
