Introduction
The water level of the machine is detected by a sensor inside and a float with magnets in the water tank.
With this error, the machine thinks that there is not enough water in the tank, despite the water tank being inserted and filled, and this is indicated by the water tank indicator light (far left) flashing red. (see also video)
Due to the aging of the magnet, as well as vibration or temperature, the magnet in the water tank can lose its strength.
It is not possible to replace this magnet or the float without destroying the water tank or replacing it completely.
However, the solution to this is to optimize the position of the sensor inside the device.

There is a one important missing step before runing a spudger around the lid to loosen the clips.
there is one additional screw under the red (Max )button , you need to remove the selecon lid cover unscrew this last one before trying to remove the Lid
In my case there wasn`t, as you see in the pictures in Step 4 and Step 6, which model did you try to open (exact Model-number) as identified on the device page Tchibo Cafissimo Mini Reparatur.
Can you provide pictures of the model identification and the missing Screw? Thanks!
