Tumble Dryer
F05
The F05 error code on a Hoover tumble dryer signals a fault with the appliance’s NTC temperature sensor or a related overheating issue — it’s a moderately serious fault that will stop your dryer from running until it’s resolved.
What does this error mean?
The F05 code means your dryer’s control board has detected an abnormal temperature reading from the NTC (Negative Temperature Coefficient) sensor, which monitors heat levels inside the drum. This either means the sensor itself has failed and is sending incorrect readings, or the dryer is genuinely overheating due to restricted airflow. Left unaddressed, persistent overheating can damage internal components or, in a worst case, pose a fire risk.

🔍 Likely causes
🛠️ Step-by-step fix
Power off and unplug the dryer — always start here before touching anything. Wait 15–20 minutes to let the appliance cool fully before inspecting.
Clean the lint filter thoroughly. Remove it from the door aperture, peel off any compacted fluff, and rinse under a tap if needed. A blocked filter is responsible for a large proportion of F05 faults.
On condenser models, remove and rinse the condenser unit (usually behind a flap at the bottom front). Hold it under running water until the water runs clear, then leave it to dry completely before refitting.
Check the exhaust vent hose (vented models) for kinks, blockages, or a clogged external wall vent. Disconnect the hose and push a broom handle through to clear any compacted lint.
Plug the dryer back in, run a short empty cycle, and check whether the F05 code returns. If it clears, the blockage was the cause — make a habit of cleaning the filter after every load.
If the F05 persists after all cleaning steps, do not attempt to open the back panel or touch internal wiring. The NTC sensor or wiring harness will need professional diagnosis — stop here and call an engineer.
📞 When to call a professional
If cleaning the filter, condenser, and vent hose doesn’t clear the F05, the fault is almost certainly internal — a failed NTC sensor, damaged wiring, or a faulty heating element. Call a Hoover-approved or reputable local appliance engineer and tell them: ‘I have an F05 error code on my Hoover tumble dryer, I’ve cleaned all filters and the vent, and the fault persists.’ Do not attempt to access internal electrical components yourself.
⚖️ Repair or replace?
A professional repair for an NTC sensor or wiring fault typically costs £80–£130 in the UK including parts and labour. If your dryer is under 5 years old, repair is almost always worth it. If it’s 8 years or older and out of warranty, weigh the repair cost against a new mid-range Hoover condenser dryer (£250–£400) — replacement starts to make financial sense if a second fault follows within 12 months.
