How to insert your green sealing ring · Thermomix Australia and New Zealand (official)
  1. 1Take the lid off the mixing bowl and put it upside down on your bench.
  2. 2Pull the old ring out of the lid. If it is grey, don't use it again: Thermomix says the TM31 must only be used with the green ring.
  3. 3Push the new green ring into the three hinges on the lid until you hear it click.
  4. 4Check the ring sits evenly all the way round. Take it out to wash it separately when you clean the lid.
