What F3 Means
F3 means the cooktop has detected that part of the touch-control sensor strip is covered by an object and is blocking it from working correctly.
Common Causes of F3
- An object physically resting on the control sensor strip
- Spilled food or liquid pooled on the control area
🔧 One Safe Check You Can Try
This one is genuinely DIY in most cases — clear anything resting on or near the control strip (a towel, a utensil, spilled food) and the fault should clear.
⚠ Why You Shouldn't Go Further Than That
- None — clearing the sensor strip is safe and immediate; only call if the alert persists on a genuinely clean, clear surface.
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.
