Bosch Cooktop F4 (Electric / Induction / Gas) error code

Difficulty: Easy · Cost: $0 · Duration: 5–20m

The F4 code on your Bosch cooktop means the electronics overheated and all cooking zones switched off to prevent damage. Wait until the electronics cool down sufficiently then touch any control element — when the F4 message disappears all zones can be used again. For gas cooktops this means the automatic ignition overheated.

Common causes

  • Multiple cooking zones were operated at high power simultaneously for an extended period
  • Electronics overheated severely due to insufficient cooling or ventilation

  4. 4
