--- title: "Bosch cooktop showing F8 | CooktopRepair.center" description: "What F8 means on Bosch cooktops, what to check before booking, and when it is not a failure at all." url: "https://cooktoprepair.center/error-codes/bosch-f8/" --- # Bosch cooktop showing F8 F8 is Bosch's automatic time limit. ## 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. Bosch cooktop display What to do when F8 shows on the cooktop ### Kind of code Mode, 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 to No repair Touch any key to clear F8, then set the zone again. ### Shows up as Cooktop 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. ### Make Bosch A German maker whose US site lists gas and induction cooktops for building into the counter. ### Source Bosch cooktop and rangetop error codes (US support) Listed for Bosch electric and induction cooktops. ## 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. 01 Touch any key to clear F8, then set the zone again. 02 If H or h shows next to F8, keep hands off that zone until the indicator goes out. 03 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. ## What you may notice with it. The cooktop problems F8 tends to arrive with. Answer these at the cooktop before anyone is booked.

Touch any key to clear F8, then set the zone again. ### Why did my Bosch cooktop turn off my stockpot with F8? A long simmer at one setting looks the same to the cooktop as a pan left on by mistake. Touch any key and set the zone again. ### Is F8 a sign my Bosch cooktop is failing? Not when it follows hours at one setting. It only needs a look if it appears after a few minutes of use. ### What does the H beside F8 on a Bosch cooktop tell me? It is the residual heat indicator that Bosch shows next to F8. The time limit has switched the zone off, but the glass is still warm. Wait for it to go out before wiping the surface. --- **[Read on the site: Bosch cooktop showing F8 | CooktopRepair.center](https://cooktoprepair.center/error-codes/bosch-f8/)** **[Book a visit with CooktopRepair.center](https://cooktoprepair.center/schedule/)**
