What Some Keys Not Working Means
When only part of the panel answers, or the display behaves oddly without showing a code, Bertazzoni's troubleshooting table puts it down to a board or display error. The remedy printed against it is to disconnect the hob from its supply, reconnect after a short time, and call an electrician if it persists.
Common Causes of Some Keys Not Working
- A control or display board glitching after a brown-out or surge
- A ribbon connection between panel and board working loose
- A genuinely failed section of the touch panel
🔧 One Safe Check You Can Try
Take the supply off at the breaker, leave it a minute or two rather than a second, and switch back on. That is the published step, and it is worth doing once properly before assuming a part has failed.
⚠ Why You Shouldn't Go Further Than That
- Isolate the cooktop at the breaker before any part of it is opened, since the panel wiring runs alongside the coil supply under the glass.
- A panel that is half working still commands real power to the zones, so continuing to cook on the keys that respond leaves you relying on a control the machine has already reported as failing.
- Panels and control boards are separate parts with similar signs, and the wrong one bought on appearance is a common way to spend money twice.
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.
