The blender jar leaks. What should I do?

• Switch the appliance off and pour out the ingredients. Remove the blade unit interface. Check if the sealing ring has been assembled properly on the blade unit.
• Then assemble the parts again:

  • Place the sealing ring on the blade unit
  • Assemble the blade unit onto the blade unit interface
  • Screw the blade unit interface onto the bottom of the blender jar until it is fixed properly

Hint: Do not put the sealing ring into the dishwasher because it will become brittle.
