Check the power cable is fully extended from the Thermomix.Check the three rubber scale sensors (the feet) under the Thermomix to ensure they are clean and there is nothing stuck to them, such as a grain of rice or sugar.The manufacturer does not recommend your Thermomix be placed on a board or a mat.Ensure the benchtop is solid and does not rock. Check that your bench is flat, and the Thermomix is not sitting on a join.For example, for an item weighing 1kg, the error tolerance would be approximately 15g, so if your Thermomix displays 990g when the item’s actual weight was 1000g, the result is within the tolerance for error. This error tolerance is less for lesser weights. When you do the scales test using packaged foods, bear in mind that food manufacturers will often put in marginally more than the advertised weight (often 10-30g for a 1kg pack) and you’ll also need to allow for the weight of the packaging.Īlso note, there could be a variance of 30 grams (up or down) at 2kgs due to calibration tolerances set by the manufacturer. Here’s a simple test you can do now to find out if your Thermomix needs to come in for a service.
