Tumble Dryer
F07
The F07 error code on a Miele tumble dryer indicates a fault with the heating circuit — specifically that the appliance is not reaching or maintaining the correct drying temperature. It’s a moderately serious fault that will stop your dryer from drying clothes properly, but in many cases it’s something you can resolve yourself without calling an engineer.
What does this error mean?
F07 tells you that the dryer’s control board has detected a problem in the heating system — either the heater isn’t activating, isn’t reaching the target temperature, or the thermal safety cut-out (also called a thermostat or thermal fuse) has tripped or failed. Miele dryers monitor temperature continuously, and F07 is triggered when the sensor readings fall outside the expected range during a cycle. Think of it as the dryer saying: ‘I’m trying to heat up, but something is stopping me.’

🔍 Likely causes
🛠️ Step-by-step fix
1. Clean the lint filter and condenser — Remove and thoroughly clean the lint filter (inside the door) and the condenser unit (usually behind a flap at the bottom front). Rinse the condenser under a tap, let it dry fully, and refit it. A blocked condenser is the single most common cause of F07.
2. Reset the dryer — Once the filters are clean, switch the dryer off at the wall socket, wait 10 minutes, then power it back on and run a short cycle. This allows any tripped thermal safety device to reset if it hasn’t permanently blown.
3. Check the machine isn’t overloaded or in a hot room — Miele dryers need adequate airflow around them. Make sure the room is ventilated and you’re not cramming too many clothes in; overloading causes overheating and can trigger F07.
4. Inspect the thermal cut-out fuse (if confident with basic appliance checks) — If the error persists after cleaning and resetting, the thermal fuse may have permanently blown. You can access it by removing the back panel. Use a multimeter to test for continuity — no continuity means it needs replacing. Replacement fuses for Miele dryers cost £8–£20 from appliance parts suppliers. STOP HERE if you are not comfortable working around electrical components — call a professional.
5. Test the heating element — With the back panel removed, test the heating element terminals with a multimeter. A reading of infinite resistance (open circuit) confirms the element has failed and needs replacing. Miele heating elements typically cost £30–£70 for the part.
6. If all components test fine, the NTC sensor or PCB may be at fault — At this point, accurate diagnosis requires professional tools. Book an engineer rather than replacing expensive parts speculatively.
📞 When to call a professional
If cleaning the filters and resetting the machine doesn’t clear F07, and you’re not confident testing electrical components with a multimeter, call a Miele-approved or reputable independent appliance engineer. Tell them: ‘My Miele tumble dryer is showing error code F07 — I’ve cleaned the condenser and lint filter and reset the machine, but the fault persists.’ This gives them a head start and may reduce your call-out time.
⚖️ Repair or replace?
A professional repair for F07 — covering a thermal fuse, heating element, or NTC sensor — typically costs £80–£160 all-in for parts and labour in the UK. If your Miele dryer is under 8 years old, repair is almost always worth it; Miele machines are built to last 10–20 years and parts are widely available. If the machine is over 10–12 years old and the control board (PCB) has failed, replacement may make more financial sense — a new mid-range Miele condenser dryer costs £600–£1,000, so weigh repair costs carefully.
