Tumble Dryer
F07
The F07 error code on a Bosch tumble dryer indicates a fault with the heating circuit — specifically that the appliance isn’t reaching or maintaining the correct drying temperature. It’s one of the more common Bosch dryer faults and ranges from a simple blockage fix to a component replacement.
What does this error mean?
F07 means your Bosch dryer’s control board has detected that the drum isn’t heating properly during a cycle. The appliance monitors internal temperature continuously, and F07 triggers when the heating element fails to reach the expected level or cuts out too early. This could be a safety thermostat tripping, a failed heating element, or restricted airflow causing overheating and auto-shutoff.

🔍 Likely causes
🛠️ Step-by-step fix
Reset the dryer: switch it off at the wall, wait 5 minutes, then power it back on and run a short cycle to see if F07 clears — a tripped thermostat sometimes resets itself.
Clean the lint filter thoroughly: remove it, wash it under warm water if coated in residue, dry it completely, and refit it before running again.
Clean the condenser unit (heat pump or condenser models): remove the condenser from the bottom panel, rinse it under a tap until the water runs clear, allow it to dry, and refit it.
Check the exhaust hose (vented models): ensure it isn’t kinked, crushed, or blocked with lint. Disconnect it and clear any obstruction, then reattach securely.
Inspect the back of the dryer for the thermal cutout: if you’re comfortable with basic appliance work, switch off and unplug the machine, remove the back panel, and use a multimeter to test the thermal cutout for continuity. A reading of ‘OL’ (no continuity) means it needs replacing — a like-for-like Bosch part costs £10–£25.
If none of the above resolves F07, do not attempt to test or replace the heating element or control board yourself — call a qualified appliance engineer.
📞 When to call a professional
If cleaning filters and resetting the machine doesn’t clear F07, you’ll need an engineer to diagnose whether the heating element, NTC sensor, thermal cutout, or control board has failed. When calling, tell them: ‘My Bosch tumble dryer is displaying error code F07 and is not heating.’ Having your model number ready (found inside the door rim) will help them bring the right parts.
⚖️ Repair or replace?
A professional repair for F07 — typically a heating element or thermostat replacement — costs £80–£150 including labour in the UK. If your dryer is under 5 years old, repair is almost always worth it. If it’s over 8–10 years old and out of warranty, weigh the repair cost against a new mid-range condenser dryer at £300–£450; a single repair at half the cost of replacement is a reasonable threshold.
