A homeowner in Wrightville, Gatineau called TechVill about a broken glass-ceramic surface on their Bosch 800 Series induction unit (model HIIP057C/05). On induction cooktops, a cracked top is not a cosmetic issue — the appliance is unsafe to operate until the surface is replaced as a single bonded assembly. TechVill technician Sharanjit handled the parts-driven repair end-to-end, including the technical reseating of the control hub and coil pack onto the new glass.
The cracked top, seen from working angle. On a Bosch induction unit the glass-ceramic surface is not a separate panel that can be patched — it is the substrate to which the touch-control PCB and coil-pack wiring are bonded. A break of this severity disqualifies the cooktop from safe operation: the coils sit directly under the surface, and any compromise to the glass changes how heat and electromagnetic field interact with cookware above it.
The damage pattern — a curved fracture with radial cracks — is consistent with a localised impact. Glass-ceramic of this grade tolerates heat cycles well but is brittle under point loads, which is why a single dropped pan or cast-iron mishandling will fault a surface that otherwise has years of service life left in it.
Confirming the model from the nameplate before sourcing. On Bosch induction units the glass top is keyed to the specific model — the cutouts, coil-pack alignment, and control-hub pinout vary across the catalogue. Ordering off a visual match rather than the printed model number is the most common way these jobs come back as a return visit, so the model plate gets verified before the part is pulled from the supplier.
Replacement complete and back on power. The new OEM glass top assembly was sourced from Bosch service inventory, transported and installed without edge damage — itself a meaningful detail, because Bosch surfaces ship as a single bonded sheet with the control hub already affixed, and dropping a corner during install turns a repair invoice into the cost of a second part. The control hub, coil pack, and wiring harness were transferred and reseated onto the new surface; the cooktop was powered up and run through its function check.
Surface detail after the install — clean cooking-zone reference marks, the touch-control row registering input cleanly, no edge chips or seating gaps against the countertop cut-out.
The Result
Total invoiced: $1,634.85 CAD for the OEM glass top assembly, parts, and labour — including the transfer of the control hub and coil pack to the new surface. The cooktop returned to normal operation in the same visit.
A comparable Bosch induction slide-in replacement installed runs roughly double this figure, before counting countertop cut-out adjustments or removal of the existing unit. The repair preserved the existing kitchen integration at a fraction of replacement cost.
What This Repair Reflects
Bosch authorises TechVill for service across our coverage areas, which gives technicians access to manufacturer service procedures and genuine OEM glass assemblies — including the keyed part-to-model lookups that prevent the wrong panel from being sent on an aftermarket guess. On induction cooktops the surface is structural to the appliance’s electronics, not just a wear part, and that authorization is what makes the OEM-only sourcing routine rather than a parts-hunt.
