How often should I replace the Thermomix TM7 mixing knife?

Heavy users who crush ice or mill grains daily should replace it every 6 months; moderate users every 2 years; light users every 4 years.

My TM7 weighs inaccurately. What can I do?

Make sure the machine sits on a level, non-slip surface, the power cord is loose, and nothing touches the base during weighing.

Where can I recycle my old TM7 in the UK?

Take it to your local council's WEEE collection point or arrange a collection with Vorwerk UK.
