Tumble Dryer
F02
The F02 error code on an Electrolux tumble dryer indicates a problem with the NTC temperature sensor — the component responsible for monitoring the heat inside your drum. It’s one of the more common fault codes on Electrolux dryers, and while it sounds alarming, it’s often caused by something straightforward like a blocked filter or a faulty sensor that can be replaced without too much hassle. In this guide, you’ll learn exactly what’s triggering the F02 code, the most realistic causes, a safe step-by-step troubleshooting process, and honest advice on whether to repair or replace your machine.
What does this error mean?
The F02 error code on an Electrolux tumble dryer is a temperature-related fault. Specifically, it means the appliance’s control board has detected that the NTC (Negative Temperature Coefficient) thermistor — a small sensor that continuously monitors the air temperature inside the drum — is either reading outside its expected range, sending no signal at all, or producing an erratic reading the board doesn’t trust. In plain English: your dryer’s ‘thermometer’ isn’t working properly, so the machine has shut itself down as a safety precaution to prevent overheating or a fire hazard. This is actually your dryer doing exactly what it should — protecting itself and your home. The F02 code is distinct from an overheat thermostat trip (which is more commonly an E61 or similar); F02 is specifically about the sensor circuit itself rather than an actual overtemperature event.

🔍 Likely causes
🛠️ Step-by-step fix
Step 1 — Reset the machine first: Switch the dryer off at the wall socket, leave it unplugged for at least 5 minutes, then plug it back in and run a short cycle. A one-off software glitch can occasionally trigger F02, and a hard reset clears it at no cost and in under 10 minutes.
Step 2 — Clean the lint filter thoroughly: Remove the lint filter (usually located inside the door rim) and clean off all fluff under running water if it’s a foam-type filter, or brush it clean if it’s a mesh type. A blocked filter is the number one cause of F02 — do this before anything else.
Step 3 — Clean the condenser or heat exchanger: On condenser and heat-pump models, locate the condenser behind the kick plate at the bottom front of the machine. Remove it according to your model’s manual and rinse it gently under a low-pressure cold tap until water runs clear through it. Allow it to dry fully before refitting. You’ll need no tools for most Electrolux models — the panel clips open.
Step 4 — Empty and clean the water reservoir: On condenser dryers, pull out the water collection drawer and empty it fully. Rinse the drawer to remove any limescale or residue. A full or blocked drawer can occasionally contribute to thermal issues.
Step 5 — Check the machine’s location and ventilation: Make sure there is at least 5cm of clearance around the dryer and that it is not in a sealed cupboard or a very warm room. If the room temperature regularly exceeds 30°C, move the dryer to a cooler, better-ventilated spot and see if the code clears.
Step 6 — Run a test cycle and monitor: After completing steps 1–5, run a full cycle with a small load of damp laundry. If the dryer completes the cycle without showing F02, the fault was airflow-related and is now resolved.
Step 7 — Inspect the NTC sensor wiring (visually only, no tools inside the appliance): Without opening the back panel, check whether there is any visible wiring damage near the door seal area or where the drum meets the front panel. If you can see a clearly disconnected or melted wire without needing to open the casing, note it down to tell your engineer. DO NOT open the back panel, remove any screws, or touch internal wiring — this requires a qualified appliance technician.
Step 8 — Look up your specific model number: Your model number is on a sticker inside the door rim. Search ‘[your model number] NTC sensor’ on a reputable UK parts site such as eSpares or 4ourhouse to confirm part availability and cost before deciding whether to call a professional or replace the machine.
📞 When to call a professional
If the F02 error code returns after you have completed all the DIY steps above — particularly cleaning the filters and condenser and performing a hard reset — it is time to call a qualified appliance engineer. At this point, the fault almost certainly lies inside the machine: a failed NTC thermistor, a damaged wiring loom, or a faulty main PCB. These repairs involve removing rear panels, disconnecting internal wiring, and working near the heating circuit or heat pump components. This is not DIY-safe territory for a non-specialist. When you call, tell the engineer: ‘My Electrolux tumble dryer is showing an F02 error code. I’ve cleaned the filters and condenser, emptied the water drawer, and done a hard reset — the fault has returned.’ This information will save them diagnostic time and may reduce your call-out charge. Look for an engineer registered with a reputable trade body such as the Domestic Appliance Service Association (DASA) or one who is Which? Trusted Trader approved. Always ask for a fixed diagnostic fee upfront — typically £60–£90 in the UK.
⚖️ Repair or replace?
Here’s the practical breakdown for UK homeowners. If your Electrolux tumble dryer is under 5 years old, a professional repair almost always makes financial sense — a new NTC sensor costs around £10–£20 in parts, and even with labour the total repair bill should be well under £150, which is a fraction of the cost of a new mid-range dryer (typically £350–£700 for a comparable Electrolux condenser or heat-pump model). If the fault is a failed main PCB, costs rise sharply: PCB replacement including labour can reach £200–£280, at which point the maths get tighter. If your dryer is 8 years old or more and this is not the first fault, replacement is worth serious consideration — Electrolux parts availability is generally good for machines up to around 10 years old, but labour costs mean older machines can become uneconomical to repair. Heat-pump Electrolux dryers (such as the EW7H3 and EW9H series) are more expensive to replace (often £500–£800+), so repairing these is nearly always worth it unless the PCB or compressor has failed. As a rule of thumb: if the repair quote exceeds 50% of the cost of a comparable new machine, replace it.
