Oven
F06
The F06 error code on an Indesit oven indicates a fault with the door lock mechanism or door lock switch — it’s a moderately serious fault that will prevent the oven from operating safely until resolved.
What does this error mean?
F06 tells you that the oven’s control board has detected a problem with the door locking system — most commonly on models with a pyrolytic (self-cleaning) function, where the door must lock securely before high-temperature cleaning begins. The board is either not receiving the correct signal from the door lock switch, or the lock mechanism itself has failed to engage or release. This is a safety-critical circuit, so the oven will lock you out of normal use until the fault is cleared.
Est. repair cost
£80–£130 for door lock repair; £120–£200 for PCB replacement. DIY door seal: £10–£25.
🔍 Likely causes
🛠️ Step-by-step fix
Reset the oven first: switch it off at the wall socket, wait 5 minutes, then power it back on. F06 sometimes clears after a temporary software glitch.
Inspect the door for obvious misalignment — open and close it firmly and check it sits flush against the frame. Tighten any loose hinge screws with a Pozidrive screwdriver if needed.
Clean the door lock area: use a damp cloth to remove grease or debris around the latch recess on the door frame. A blocked latch is a common and overlooked cause.
Check the door seal (gasket) — a swollen or displaced seal can stop the door closing fully and prevent the lock from engaging. Replacement seals cost £10–£25 and clip in without tools.
If the oven is stuck in a locked state after a pyrolytic cycle, try a hard reset: isolate the appliance at the fuse board for 15–20 minutes, then restore power. This can release a stuck lock motor.
If none of the above works, the door lock assembly or PCB likely needs replacing — do not attempt to dismantle the lock mechanism or access the control board yourself; call a qualified engineer at this point.
📞 When to call a professional
Call an engineer if the oven door remains locked and will not release after a hard reset, or if the F06 code returns immediately after clearing. Tell them you have an Indesit oven showing error code F06 and that you suspect a door lock switch or lock motor fault — this helps them bring the right part. Any work involving the wiring harness or PCB must be carried out by a qualified appliance repair technician.
⚖️ Repair or replace?
A door lock assembly replacement typically costs £80–£130 all-in for parts and labour in the UK; a PCB replacement is higher at £120–£200. If your Indesit oven is under 5 years old, repair is almost always the better value. Over 8 years old, weigh repair cost against a new oven starting at around £300–£400 — if the quote exceeds 50% of replacement cost, replacing is the smarter move.
