Bosch Induction Cooktop Broken Glass: Safe Next Steps

Use only checks that match the exact appliance or system and its official guide.

1. Check 1

   Stop cooking and inspect the glass visually from a safe position, without touching it. Wait for the surface to cool and for any residual-heat indication to clear before approaching; note whether the mark is a shallow surface scratch, a crack, a chip with a sharp edge, a spiderweb pattern, or loose or missing glass.

   Expected result: The mark remains a shallow scratch with no crack or chip; a crack or chip crosses the cooking surface; or glass is loose, missing, or fragmented.

   Next step: If there is any crack, chip, loose fragment, or uncertainty about the mark, stop using the cooktop and continue with the power-isolation and service handoff. Do not resume cooking to test a damaged surface.

   Why this matters

   Why: Bosch describes small surface scratches as cosmetic, while a cracked or broken surface can cause cuts and create an electrical shock risk. The visible pattern changes the decision before any control or error-code troubleshooting.

2. Check 2

   Without wiping across the damaged area or pouring anything onto it, look for spilled food, cleaner, or other liquid that has reached the crack or broken edge. Keep cookware and objects off the damaged glass, and do not try to seal the break with tape, glue, or a homemade cover.

   Expected result: The damaged area is dry and isolated; a spill or cleaning liquid is present near or in the break; or the edge is lifting and could shed glass.

   Next step: Leave the cooktop out of use in every case involving a crack or break. Keep people away from loose fragments and arrange authorized service rather than attempting a cosmetic patch or user repair.

   Why this matters

   Why: Bosch warns that cleaning solutions and spillovers may penetrate a broken cooktop and create an electric-shock risk. A dry appearance does not make a cracked surface safe, and a loose edge also adds a cut hazard.

3. Check 3

   If the controls still respond, use the normal power control once without repeatedly pressing it. Observe whether every cooking zone stops heating and whether the display enters its normal standby state; do not reach over a hot or broken area to test another control.

   Expected result: All zones stop and the display settles normally; a zone continues heating; the display remains active or shows a fault; or the panel, cord, or surrounding wiring shows smoke, sparks, burning odor, or visible damage.

   Next step: If the breaker or disconnect is safely accessible without touching the appliance or wiring, switch it off; otherwise move clear and obtain qualified help. Do not keep testing the controls or open the cooktop.

   Why this matters

   Why: A normal control response does not remove the cracked-glass safety restriction. Continued heating or any smoke, sparking, odor, or electrical damage makes the situation urgent and may indicate a separate control or supply fault alongside the broken surface.

4. Check 4

   Record the complete Bosch model number (E-Nr.), FD or production number, the location and extent of the glass damage, and whether a zone was heating or the controls failed. Use a photo taken from a safe distance for the service handoff, without moving fragments or removing any panel.

   Expected result: The model and production identifiers are available; only the surface appears damaged; or the damage is accompanied by control, heating, or electrical symptoms.

   Next step: Give the identifiers and observations to a Bosch authorized servicer. Let the servicer determine whether the correct repair is a glass-ceramic surface, a cooktop assembly, or another model-specific part; do not order a generic panel.

   Why this matters

   Why: Bosch's parts and service resources are model-specific, and a surface replacement cannot be selected safely from the symptom or appearance alone. Additional heating or control symptoms may require diagnosis of the complete cooktop assembly.
