F5
Bosch F5 on induction cooktop: hot cookware near the panel
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Low
Quick answer
Your Bosch induction cooktop shows F5 because there is hot cookware near the control panel and the electronics are at risk of overheating. Remove the cookware from the panel; if the zone also switched off, wait a few seconds and touch any control.
Safety first

Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Cookware position
- Who:
- you.
- How:
- remove any hot pot, pan or lid sitting on or very close to the control panel, as Bosch instructs.
- Result that matters:
- whether F5 clears and the power level stops flashing.
- If it clears and you keep cooking:
- it was the early warning variant.
- If the zone was already off:
- continue with the next step.
- Evidence to keep:
- a note of which cookware was next to the panel.

Reactivate the switched off zone
- Who:
- you.
- How:
- with the cookware removed, wait a few seconds and touch any control on the cooktop, as Bosch instructs.
- Result that matters:
- the message clearing and the zone available to set again.
- If it clears:
- the zone only switched off as protection; keep cooking.
- If F5 stays with no cookware near the panel:
- let the cooktop cool and, if it does not clear, contact Bosch service.
- Evidence to keep:
- a photo of the message if it persists with nothing nearby.

Usage habit to prevent repeats
- Who:
- you.
- How:
- avoid resting hot cookware, lids or utensils on the control panel strip while cooking.
- Result that matters:
- F5 not returning in normal use.
- If it does not return:
- cookware position was the cause.
- If it returns with nothing near the panel:
- that does not fit Bosch's meaning and service should be told.
- Evidence to keep:
- notes of when it returns, if it does.

What it means
Bosch describes two F5 variants on its induction cooktops. If F5 alternates with the power level and the cooktop beeps, there is hot cookware near the control panel and the electronics are at risk of overheating. If F5 appears with beeping and the zone switches off, the cooktop has already cut that zone to protect the electronics. In both cases the warning reflects where the cookware sits, not a cooktop fault.
Warnings and stop conditions
