Why does my Bosch Kitchen Appliance switch off during use?
- J
  Jordan ButlerAug 15, 2025
  Your Bosch Kitchen Appliance might be switching off during use due to several reasons. It could be that too much food is being processed at once or for too long. Try reducing the quantity and allow the appliance to cool down after turning the rotary switch to 'y' and disconnecting the mains plug. Another reason could be that the swivel arm was opened; in this case, turn the rotary switch to 'y', press the release button, and ensure the swivel arm is locked in place. Lastly, the bowl or bevel gear might have become loose. Turn the rotary switch to 'y', disconnect the mains plug, and tighten the bowl and bevel gear.
