Bosch induction cooktop does not detect pan: cookware and placement checks
Bosch says induction cookware needs ferromagnetic material and suggests a magnet test on the pan bottom. Its troubleshooting guidance also lists pan size and placement over the cooking zone, selected zone/power setting, and active child lock or pause as owner checks. The cited guide does not support opening the cooktop or changing electrical connections.
Safety boundary
- Do not open the glass surface, remove panels, or alter wiring.
- Follow the cooktop manual for hot-surface indicators and handling cookware.
- Stop if the glass is cracked or a warning/error remains.
Symptoms this path covers
- A Bosch induction zone does not recognize a pan
- Cookware does not heat on an induction zone
- A pan works on one zone but not another
Diagnostic sequence
- Test the pan material
Bosch says induction requires ferromagnetic cookware. Place a magnet against the base; a magnet that sticks indicates the pan can be used for induction.
Stop when: The cookware manufacturer warns against magnetic induction use or the test is inconclusive. - Check size and centering
Use a pan size suited to the selected zone and place it centered on that zone. Bosch says a pan that is too small or misplaced may not be detected.
Stop when: The cookware or cooktop manual gives different minimum pan dimensions. - Check the selected controls
Confirm the intended zone and power level. If the child lock or pause function appears active, use the exact model manual to clear it.
Stop when: A fault code appears or controls do not behave as the manual describes. - Contact Bosch if the checks do not help
If compatible cookware is centered and the correct zone is selected but detection still fails, provide Bosch support the full model and any displayed code.
Induction compatibility is about the pan base
Bosch says induction works with cookware that has ferromagnetic properties. Its simple magnet test checks the bottom material; cookware that is not magnetic may not heat on induction.
A magnetic base is only one check. Bosch also says size and placement relative to the selected cooking zone can affect recognition.
Control checks and limits
Before arranging service, confirm the zone and power setting. Bosch lists child lock or pause as possible control conditions and says its documented controls can clear them.
If a compatible centered pan still is not detected, or a code appears, get model-specific Bosch support. This symptom alone does not identify a failed coil or control board.
