What F8
actually means.
F8 is Bosch's automatic time limit. A zone left at the same setting for an extended period is switched off in case it was forgotten; with H or h beside it, the zone is still warm.

What to do when F8 shows on the cooktopKind of codeMode, not a failure
A state the cooktop was put in, or one it picked deliberately — a child lock, a demo mode that lights the keys but heats nothing, a residual-heat letter over a zone that is still warm, a prompt that no pan has been found. Nothing has broken and no part is called for.
Usually leads toNo repair
Touch any key to clear F8, then set the zone again.
Shows up asCooktop Element Not Heating
A coil stays black, a radiant ring under the glass never glows, or a zone warms so weakly that a pot of water will not boil.

Before you book,
in this order.
Each step comes from Bosch's own guidance for F8 on its cooktops. Follow it to the end: the last card says whether this is a visit.
Touch any key to clear F8, then set the zone again.
If H or h shows next to F8, keep hands off that zone until the indicator goes out.
For long simmers, change the setting now and then; if F8 appears after short use, book a visit.
Cleared?
The cooktop came right without a new part. If the same message returns while a zone or burner is on, or the top shuts itself down again mid-meal, treat it as a fresh problem and book it.
What not to do
F8 is not an overheat code and not a failed element. The timer, not a sensor, turned the zone off.
