Thermomix® scale weighs wrong or jumps

The scale shows too little, jumps back and forth or doesn’t respond at all? In most cases it’s down to where the machine stands or how it’s handled.

For the TM5 and TM6 · Mixklinik workshop · Updated November 2026

In short

The scale measures through the machine’s feet. If the Thermomix® isn’t standing freely and level, something is leaning on it or the cable is pulling, it weighs wrong. Jumps of 5 grams are normal on the TM5.

How to weigh correctly

  • Stand it on a flat, hard, smooth surface. All feet must be in contact.
  • Don’t lean anything against the machine, no tea towels or cables underneath, and no tension on the power cable.
  • Don’t touch the machine or press on the lid while weighing.
  • Add ingredients slowly and tare before each new ingredient.
  • For oil: stand a jug on the lid, tare, then pour.

Lift it, don’t slide it. Pushing or pulling the Thermomix® across the worktop puts a sideways load on the scale. Vorwerk recommends lifting the machine. If you move it often, use a slider board.

What’s normal

  • TM5: the scale counts in 5-gram steps from 5 to 3000 g. Small jumps are normal.
  • TM6: the display counts in 1-gram steps, and in 5-gram steps while the motor is running.
  • Weighing while cooking only works at low speeds.

Test the scale

Take an unopened 1 kg bag of sugar or flour. Fit the bowl with the lid, tare and place the bag on the lid. The reading should be close to 1000 g; a few grams either way is normal. If the scale shows clearly too little or fluctuates a lot even though it’s standing properly, the load cell is usually damaged, for example after a knock or a fall.
