Bosch slide-in ranges are designed with front controls and an integrated flush fit against standard 24-inch deep countertops.

All Bosch 800 Series slide-in ranges use the same E-code fault system (E101, E115, E118, E126, E302, E303, E310) monitored by the main control board. Error codes display on the 7-segment or LCD display panel and can also be reviewed in the range’s Service Mode diagnostic menu.
