Tumble Dryer
F09
The F09 error code on an Indesit tumble dryer indicates a fault with the electronic control board or its internal memory (EEPROM), and while it sounds alarming, it’s not always terminal — a simple reset can sometimes clear it entirely.
What does this error mean?
F09 signals that the dryer’s main control board has detected a problem reading or writing to its EEPROM memory chip — the small component that stores the machine’s settings and operating data. In plain terms, the brain of the machine has either had a temporary glitch or suffered a more permanent hardware fault. If the error clears after a reset and doesn’t return, it was likely a one-off power surge or software hiccup; if it keeps coming back, the control board itself is suspect.

🔍 Likely causes
🛠️ Step-by-step fix
Power off and unplug the dryer completely. Leave it unplugged for at least 10–15 minutes to allow any residual charge to fully discharge and the control board to reset.
Check your home’s consumer unit (fuse box) for a tripped RCD or circuit breaker on the relevant socket circuit. Reset it if tripped, then plug the dryer back in.
Clean the lint filter and, if your model is a condenser dryer, remove and rinse the condenser unit under a tap. A blocked condenser causes overheating that can stress the PCB and trigger memory faults.
Reconnect the power and run a short test cycle. If F09 clears and the dryer runs normally, monitor it over the next few uses — a one-off occurrence after a power event is usually harmless.
If F09 returns repeatedly, check that the plug and socket are delivering a stable power supply. Try plugging the dryer into a different wall socket (not an extension lead) to rule out a dodgy outlet.
If none of the above resolves it, the control board (PCB) is the most likely culprit. Replacing a PCB involves accessing internal electrical components — stop here and call a qualified appliance engineer rather than attempting this yourself.
📞 When to call a professional
Call an appliance repair engineer if F09 persists after a full power reset and filter clean, or if it reappears within a few cycles. Tell them: ‘My Indesit tumble dryer is showing an F09 error code, which I understand relates to a control board or EEPROM memory fault.’ A qualified engineer can test the PCB with a multimeter and confirm whether the board or a wiring harness is at fault before ordering parts.
⚖️ Repair or replace?
A replacement PCB for an Indesit tumble dryer typically costs £40–£90 for the part alone, with labour bringing a professional repair to around £100–£180 total. If your dryer is under 5 years old, repair is almost always worth it; if it’s 8 years or older and has had previous faults, putting £150 into a machine nearing end-of-life is a poor investment — a new mid-range condenser dryer starts at around £250–£350 from UK retailers. For machines between 5–8 years old, get a quote first and weigh it against a new appliance.
