Bosch Bosch Series 2 fault codes
Formerly Classixx — Bosch confirm the rename on their own site, though they state no year for it. Model prefixes SMS, SMV, SMI and SPS with a 2 as the fourth character, so SMS26AI08G is a Series 2 rather than a Series 26.
Codes on the Bosch Series 2 follow the same Bosch scheme as the rest of the range. Where a code behaves differently on this generation, the code page says so.

- E27The mains voltage is too low. Bosch state plainly that this is not a fault on the appliance — you want an electrician, not an appliance engineer.Get it checked
