Bosch Bosch Series 6 fault codes
Formerly Avantixx. SMD is fully integrated on this range, not semi-integrated, which is a common mix-up when ordering parts.
Codes on the Bosch Series 6 follow the same Bosch scheme as the rest of the range. Where a code behaves differently on this generation, the code page says so.
Fault codes
All Bosch codes that apply to this model.
- E15The water protection system has activated — there is water in the base of the machine. Turn the tap off and call service. Do not tilt it, whatever else you read.Stop — call an engineer
- E24The machine cannot drain. Bosch publish a full owner procedure for this one, and two warnings about doing it that their UK page leaves out.Get it checked
- E18Water is not getting in. Bosch publish a full owner procedure including a flow rate you can measure with a jug.Get it checked
- E22The filters are soiled or blocked. Bosch give a one-line remedy — clean them — and it is genuinely the whole job.Get it checked
- E16Water is running into the machine continuously, whether or not it is switched on. Bosch give the same instruction as for a leak: tap off, call service.Stop — call an engineer
- E12The heating element has furred up with limescale. Descaling fixes today; setting the water softener correctly stops it coming back.Get it checked
- 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
