How to calibrate the grinder of a Krups coffee maker

A question that arises for many users of Krups super automatic coffee makers is how to calibrate the coffee grinder so that it grinds faster. While the correct time is between 6 and 8 seconds, coffee makers take between 9 and 11 seconds, which causes too much ground coffee in the piston, and the extraction is not done correctly.

If your coffee maker is under warranty, the best thing to do is to call customer service and have it calibrated by them, but if the warranty has expired, I will explain what you can do to solve this problem.

Note: Entering the service menu can lead to more serious problems, so if you do so, it is at your own risk.

  • This problem usually appears after a blockage of the grinder, which in most cases is caused by incorrect coffee beans or lack of cleaning of the Krups. Never use coffee beans that have not been roasted naturally, without sugar or other additives.
