The NGM8655UC pairs traditional gas cooking with an electronic ignition module, so faults can come from either the mechanical burner components or the electronics that spark them. Cast-iron grates and burner caps also need periodic cleaning to keep flame quality consistent.

Induction cooktops need less maintenance than gas or coil electric, but a few habits go a long way toward preventing overheating faults.

A cooktop showing “dE” and refusing to heat looks like a major failure, but it’s almost always a simple settings fix.

The NIT8668SUC is Bosch’s flagship induction cooktop, built around FlexInduction zones that can combine into one large cooking surface. Proper cabinet ventilation underneath the unit is essential to prevent the electronics-overheating faults this model can develop under heavy, sustained use.
