Hotpoint & Indesit F09 error — control board fault
⚠️ This needs a qualified professional
This fault involves gas or mains electrical work. Don't attempt a DIY repair — UK law requires gas work to be carried out by a Gas Safe registered engineer. Below is what to check and describe to them, not step-by-step repair instructions.
Unlike most fault codes on this site, F09 on a Hotpoint or Indesit washing machine isn’t a DIY-fixable symptom — it points to a corrupted memory chip or software fault on the machine’s main control board, not a blockage or worn part you can access.
⚠️ This needs a qualified engineer
There’s no safe or effective DIY check for F09. It’s included here so you can recognise it and avoid wasting time on filter/hose checks that won’t help.
What’s worth trying before you book someone
- Unplug the machine at the wall for 10–15 minutes, then try again — this occasionally clears a one-off software glitch, though it won’t fix a genuinely faulty board.
- Check your home’s electricity supply has been stable recently (no recent power cuts or surges) — this is a common trigger.
What to tell the engineer
Whether the fault returns immediately after a power-cycle attempt, and roughly when it first appeared (e.g. “started right after a power cut”) — this helps them decide quickly whether it’s a board replacement.
