Bosch Bosch Series 8 fault codes
Formerly Logixx, and rendered as both Series 8 and Serie 8 on Bosch’s own UK pages. Bosch state no launch year for any of these ranges, so none is given here.
Codes on the Bosch Series 8 follow the same Bosch scheme as the rest of the range. Where a code behaves differently on this generation, the code page says so.
