Possible Causes

How to Fix / Troubleshooting
Safety first: Immediately switch off the breaker. Do not continue to reset and operate the cooktop with this error, as it may worsen damage.
- Inspect for moisture: Check under the cooktop for signs of liquid spills reaching the electronics. Dry thoroughly and allow 24 hours before retesting.
- Verify wiring: Confirm that the cooktop is wired according to the Bosch installation diagram. Incorrect bridging or neutral/line reversal can cause overcurrent.
- Internal inspection (advanced): With power off, remove the glass and inspect the power module and coils for burn marks or cracked components.
- Replace damaged components: Replace any visibly damaged induction coil and/or power module. Due to the complexity, this repair is best handled by an authorized Bosch technician.
