Tumble Dryer
F14
The F14 error code on a Miele tumble dryer indicates a fault with the heating circuit — specifically, the appliance is not reaching or maintaining the correct drying temperature. It’s a moderately serious fault that will prevent your dryer from drying clothes properly, but in many cases it can be resolved without a professional callout.
What does this error mean?
F14 tells you that the dryer’s control board has detected a problem in the heating system — either the heater isn’t switching on, isn’t reaching the target temperature, or a safety thermostat has tripped to cut the heat. On Miele heat pump dryers, this can also relate to the heat pump cycle failing to generate sufficient warmth. The machine is protecting itself and your laundry by stopping the cycle before damage occurs.

🔍 Likely causes
🛠️ Step-by-step fix
Reset the machine: Switch the dryer off at the plug, wait 5 minutes, then switch back on and restart the cycle. A one-off thermal trip can self-reset once the machine cools down.
Clean the lint filter: Remove the lint filter at the door seal and clear it completely. A clogged filter is the single most common cause of heating faults on Miele dryers.
Clean the condenser unit: On condenser and heat pump models, remove the condenser (usually behind a flap at the bottom of the machine), rinse it thoroughly under a cold tap, and leave it to dry before refitting. Miele recommends doing this every 1–3 months.
Check the heat exchanger fins (heat pump models): Gently vacuum any fluff from the heat exchanger fins behind the condenser compartment — blocked fins drastically reduce heating efficiency.
Check your home’s consumer unit: If the circuit breaker for the dryer has tripped, reset it. A repeated trip suggests an electrical fault — do not keep resetting it; call an electrician.
If all filters are clean and the error persists after a reset, do not attempt to open the machine to test the heating element, thermistor, or thermostat yourself — these steps require disassembly of live components and should be handled by a qualified engineer.
📞 When to call a professional
If the F14 error returns after a full reset and thorough cleaning of all filters and the condenser, the fault is most likely a failed heating element, tripped thermal thermostat, faulty NTC sensor, or a heat pump compressor issue — all of which require a qualified appliance engineer. When you call, tell them: ‘My Miele tumble dryer is displaying F14, the filters and condenser are clean, and the fault persists after a cold reset.’ This will help them bring the right parts. Miele’s own service line (0330 160 6600) or an independent Miele-specialist engineer are both good options.
⚖️ Repair or replace?
A professional repair for an F14 fault typically costs £80–£180 depending on the failed component and your location in the UK. Miele dryers are built to last 10–20 years, so if your machine is under 8 years old and otherwise reliable, repair is almost always the better value. If it’s over 10 years old and this isn’t the first fault, weigh the repair cost against a new mid-range Miele condenser or heat pump dryer (£599–£1,100), and factor in that a newer heat pump model will significantly cut your energy bills.
