Bosch Cooktop Symptoms — Complete Troubleshooting Guide

Eight Bosch cooktop symptoms, covering both the NGM gas tops and the induction glass. Nonstop clicking is moisture, a misaligned burner cap or the spark module. A cooktop that will not start can be FlameSelect ignition, the child lock, induction pan detection or the control board. Sparking or arcing across the glass points at cracked SchottCeran or a damaged radiant element. Even the rust guide is specific: enamel chipped off cast-iron grates, corroded aluminium burner parts, stained stainless trim.

The first job in this hub is telling normal from faulty, because a Bosch top makes noise by design — induction hums, gas clicks once at ignition. The noise guide draws that line before naming a part, and the leak guide does the same with an even sharper split: escaping gas on an NGM burner and water pooling under an induction top are two unrelated faults sharing one complaint.

Sparking is the stop-now item. Cut power at the breaker before anything else, because cracked ceramic glass over a radiant element is live-parts exposure, not a cosmetic flaw. On the gas side, orifices, pressure adjustment and the FlameSelect valve assembly are licensed work. Wiping an electrode dry, seating a burner cap and keeping grates out of the dishwasher are yours; book the visit for cracked glass, a spark module or anything behind the glass.
