Tumble Dryer
F05
The F05 error code on a Candy tumble dryer signals a problem with the heating circuit — specifically a fault detected by the NTC (temperature sensor) or the heating element itself. It’s one of the more common Candy faults and ranges from a quick DIY clean to a part replacement, depending on the root cause.
What does this error mean?
F05 indicates that the dryer’s control board has detected an abnormal temperature reading or a failure in the heating system. This usually means the machine either isn’t heating at all, is overheating, or the sensor monitoring the temperature has failed. The dryer will typically stop mid-cycle to prevent damage or a fire risk.

🛠️ Step-by-step fix
Step 1 — Clean the lint filter: Remove and clean the lint filter thoroughly after every cycle. A clogged filter is the single most common trigger for F05. Run a cycle to see if the code clears.
Step 2 — Clean the condenser (condenser models only): On condenser dryers, remove the condenser unit (usually behind a panel at the bottom front) and rinse it under a tap until the water runs clear. Allow it to dry fully before replacing.
Step 3 — Check and clear the exhaust duct (vented models only): Disconnect the venting hose from the back of the machine and check for blockages along its full length. A crushed or kinked hose will cause overheating.
Step 4 — Reset the dryer: Once all filters and vents are clear, switch the dryer off at the wall, leave it for 10–15 minutes, then power it back on and run a short cycle. This allows any tripped thermal cut-out to reset if it is the resettable type.
Step 5 — Test the NTC thermistor (if comfortable with basic appliance repair): Unplug the machine. Access the thermistor (typically clipped to the heater housing — consult your model’s service diagram). Use a multimeter to check resistance; a healthy NTC should read around 10–50kΩ at room temperature depending on the model. If it reads open circuit or near zero, replace the part — NTC thermistors for Candy dryers cost £8–£20.
Step 6 — Stop here if the fault persists: If the code returns after cleaning and a reset, the thermal cut-out, heating element, or control board is likely faulty. These repairs involve opening the electrical components of the appliance — call a qualified engineer.
📞 When to call a professional
Call a professional if the F05 code returns after you’ve cleaned all filters, cleared the venting, and performed a reset. Tell the engineer you have a Candy tumble dryer showing F05 and that you’ve already ruled out blockages — this will save diagnostic time. Any repair involving the heating element, thermal fuse, or control board should be handled by a qualified appliance repair technician.
⚖️ Repair or replace?
A professional repair for F05 on a Candy tumble dryer typically costs £80–£130 for a heating element or thermal fuse replacement, plus the call-out fee. If your dryer is under 5 years old, repair is almost always worth it. If it’s 8 years or older and the control board has failed (£50–£80 for the part alone, plus labour), replacing the machine with a new model — budget condenser dryers start at around £250–£300 — is often the smarter financial decision.
