  Kelly CarlsonSep 15, 2025
  If the scales on your Bosch Mixer do not show any change in weight when adding ingredients, it's likely that the quantity of added ingredients is less than 5 grams (0.01 lb). Add at least 5 grams (0.01 lb) to ensure the scales provide correct measurement results.

What to do if my Bosch Mixer shows 'ADD INGREDIENTS' when using SensorControl Plus?

  Angela PhillipsSep 13, 2025
  If the Bosch Mixer's SensorControl Plus displays 'ADD INGREDIENTS' even after adding ingredients, it's likely that the ingredients were added before the scales were activated. To resolve this, empty the bowl, select the program again, and only add ingredients after the program has been selected and the scales show '0 g' or '0.00 lb', or when 'ADD INGREDIENTS' appears on the display.

  Gregory DuranSep 12, 2025
  If the Bosch Mixer displays 'ERROR MOTOR OVERLOAD', turn the rotary switch to 'y' and disconnect the mains plug. Then, reduce the amount of food being processed or the processing time, and allow the appliance to cool down. Also, check the appliance and accessories for any blockages and clear them. If the message continues to appear, the motor or scales may be defective, or the scale is exposed to vibrations. To reset the scales, hold down one of the function buttons (D/A/C) until “OptiMUM” appears on the display. Avoid using the appliance on worktops when a dishwasher is running underneath.
