What F8 Means

Documented on both platforms as the automatic time-limitation feature triggering after a cooking zone has run continuously for an extended period without any control interaction.

Common Causes of F8

  • A long, unattended cook with no control adjustments during that time

🔧 One Safe Check You Can Try

Touch any control element — the zone can then be reset and continue cooking normally.

⚠ Why You Shouldn't Go Further Than That

  • This is a built-in safety timeout, not an error — no repair is needed.

Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.

If the zone runs continuously without any control touch for another extended stretch, yes — it's a repeating safety feature, not a one-time glitch.
