Bosch HIS8655U 800 Series 36 in Induction Cooktop Flashing H Error Fix: Residual Heat Warning

The cooktop surface still has residual heat from a recently used cooking zone. This is a safety indicator, not a fault. The "H" will display until the glass surface cools to a safe touch temperature (typically below 140°F). Each zone has an independent residual heat indicator. Do not place heat-sensitive items on a zone showing the H indicator. The display will automatically clear once the surface has cooled sufficiently.
