What H Means
An H in a zone display is a warning, not an error. Bertazzoni's induction manual says it marks a zone whose glass is still hot enough to burn, and that it clears by itself once the surface has dropped to a safe temperature. The manual even suggests putting that leftover heat to use for another pan.
Common Causes of H
- A zone recently switched off after cooking, with heat still passing back from the pan into the glass
- A hot pan or dish left standing on a zone that is already switched off
- A residual-heat sensor reading high if H persists on glass that is genuinely cold
🔧 One Safe Check You Can Try
Treat the marked zone as hot and keep hands, cloths and plastics off it. Nothing needs resetting - the letter goes out on its own as the glass cools, and how long that takes depends on how hard the zone was worked.
⚠ Why You Shouldn't Go Further Than That
- The letter exists precisely because induction glass gives no other clue that it is hot, so wiping a zone showing H is a straightforward burn.
- If H stays lit for hours on a cold cooktop, the sensing is wrong rather than the glass, and that is checked with the appliance off at its breaker rather than by covering the display.
