Tumble Dryer
F08
The F08 error code on an Indesit tumble dryer indicates a heating system fault — specifically a problem with the appliance detecting or generating heat. It’s one of the more common Indesit fault codes and, depending on the cause, can often be resolved without a costly engineer call-out.
What does this error mean?
F08 signals that the dryer’s control board has detected a fault within the heating circuit. This typically means the machine is either not heating up at all, overheating, or the NTC temperature sensor is sending a reading outside the expected range. In practical terms, your clothes will come out damp because the drum isn’t reaching the temperature needed to dry them properly.

🔍 Likely causes
🛠️ Step-by-step fix
Turn the dryer off at the mains and unplug it. Wait 10 minutes, then plug back in and restart — this resets the control board and clears temporary faults.
Clean the lint filter thoroughly. If you have a condenser dryer, remove and rinse the condenser unit under a tap until the water runs clear. A blocked condenser is the single most common cause of F08 on Indesit condenser models.
On a vented dryer, check the exhaust hose from the back of the machine to the wall or window kit. Make sure it isn’t kinked, crushed, or blocked with fluff. Airflow restrictions cause the thermal limiter to trip.
Check that the room isn’t excessively hot and that the dryer has at least 10–15cm of clearance on all sides. Poor ventilation around the machine contributes to overheating faults.
If the above steps don’t clear the code, the thermal cut-out (thermal limiter) is the next most likely culprit. Replacement parts cost £5–£15 and are available on sites like Espares or 4ourhouse. However, accessing this component requires removing the back or top panel — if you’re comfortable with basic appliance repairs and the machine is unplugged, this is a manageable DIY job. If in doubt, call a professional.
Do NOT attempt to bypass or permanently wire around the thermal limiter — it is a critical safety device. If the NTC sensor or heating element needs replacing and you are unsure, stop and contact a repair engineer.
📞 When to call a professional
Call a qualified appliance repair engineer if the error persists after cleaning filters and venting, or if you suspect the heating element, NTC thermistor, or control board has failed. When booking, tell the engineer you have an F08 fault code on an Indesit tumble dryer and describe whether the drum heats at all — this helps them bring the right parts. Expect a diagnostic visit fee of £50–£80, which is often deducted from the final repair cost.
⚖️ Repair or replace?
A professional repair for an F08 fault typically costs £80–£150 all-in depending on the failed component. If your Indesit dryer is under 5 years old and the fault is a sensor or thermal limiter, repair is almost always worth it. If the machine is over 7–8 years old and the heating element or control board has failed, compare the repair quote against a new entry-level condenser dryer (from around £200–£250 at UK retailers) — at that point, replacement may offer better long-term value.
