Bosch cooktop F9 error code
PiezoControl touch-control data fault. F9 on a Bosch NIT-series induction cooktop (models such as the NIT3065UC and NIT5065UC) is a PiezoControl fault: the touch-control electronics report a data-transmission failure inside the cooktop’s control system. Bosch professional PDR and PRG ranges use the same F9 code for a different problem — the oven door-latch monitoring failed, which cancels the self-clean cycle; if the latch itself is fine, the control clock is the part Bosch names as the usual replacement.

SAFE CHECKS — IN ORDER
How to diagnose Bosch F9 yourself
Walk these checks in order before scheduling service. They isolate the most common causes safely without requiring tools or part replacements.
- 1Power-cycle at the breaker: induction cooktops are hardwired, so switch the circuit breaker off, wait 60 seconds, restore power, and re-test.
- 2Clean and dry the glass over the touch controls — dried boil-over film or standing water on the control area can disrupt the touch electronics F9 monitors.
- 3Note whether F9 appears immediately at power-up or only when you press a control, and write that down for the technician.
- 4On a PDR or PRG professional range, check the oven door latch instead: confirm it moves freely and nothing is jammed in it, especially around a self-clean cycle.
- 5If the range latch moves freely and F9 stays, stop re-running self-clean — repeated attempts will not clear a control-side fault.
