Bosch range F8 + H/h Status Message

Bosch treats F8 + H/h as an automatic time-limit event. Touching a normal control resets the state so the cooking zone can be set again.

Applies to Bosch induction range with automatic time limitation triggered

What the appliance detected

Detected condition

The automatic time limitation triggered and stopped heating because the cooking zone had been running too long without interaction.

What may contribute

Possible causes

  • A cooking zone may have been left running for an extended period without control input.
  • Long unattended simmering or warming can trigger the automatic time limit.
  • If the message appears during short normal use, a model-specific control issue may need review.

Start conservatively

Safe preliminary checks

Work in order and stop whenever a step is not supported by the documentation for your model.

  1. Confirm the exact F8 + H/h message

    • Record the display and verify the model documentation describes this automatic time-limit condition.
    • Confirm there is no separate overheating or electrical fault displayed.
  2. Acknowledge the time limit

    • Bosch says to touch any normal control element on the cooktop.
    • Set the zone again only if continued cooking is safe and supervised.
  3. Review long unattended operation

    • Use timers and normal supervision for extended simmering or warming.
    • If the message occurs unexpectedly during short operation, stop and consult Bosch support.

Actions not recommended

  • Do not bypass the automatic time limitation or use hidden service settings to defeat it.
  • Do not assume the status means the induction module has failed.
  • Do not leave a reset cooking zone unattended after a time-limit event.

When to stop and request service

  • F8 + H/h occurs during short normal use rather than extended operation.
  • The controls do not recover after the documented acknowledgement.
  • A different overheating, voltage, or electronics fault appears.
