Bosch 800 Series and Benchmark induction cooktops: quick sheet

Each zone is a flat copper coil under the glass, driven by an inverter on the power (induction) board. The inverter rectifies the 208-240 V supply to a high DC bus and switches it at high frequency through the coil; the alternating magnetic field induces current directly in a ferromagnetic pan base, so the pan heats and the glass only warms from the pan. A temperature sensor under each coil and sensors on the power electronics let the control limit power and shut a zone down when something overheats.

Pan detection: when a zone is switched on, the board pulses the coil and judges the load. A non-magnetic, too-small or badly off-center pan is rejected and the power level display flashes; on BSH cooktops the zone switches itself off if no suitable pan is found within roughly 90 seconds. FlexInduction areas are built from several coils that the control combines when cookware covers them; on flex models with the 'moving pot' feature (marketed as PowerMove), the flex area is split into front, middle and rear sections with preset power levels, so sliding the pan changes the heat.

Cooling: a fan under the glass pulls air across the power board heat sinks and exhausts it, and it can keep running after cooking until the electronics cool. If the electronics get too hot (blocked ventilation, hot cabinet, hot pan resting near the controls), the control derates or shuts zones off and shows F2/F4/E7015 or F5. SpeedBoost/PanBoost borrow power from the neighbouring zone, which is why two zones on the same side cannot both run at full boost.

Supply monitoring: the control checks the incoming voltage at power-up and during use. A supply outside the acceptable range (wrong wiring, a missing leg, a bridged connection) is reported as U400 or E9000/E9010. Home Connect models also report network/hood pairing problems as E7010; that code does not stop the cooktop from cooking.
