The solution is a tapping cup with this "stick" in the centre.
Then you tap on the rod and the sieve can't possibly fall out.

It always happens to me, what is the solution?

It happens to us from time to time, but not always. But our machine is also a few years old. So I'm sure I have an older version. The springs have probably been changed.

It happens to me too, but not every time.

That's right, or the sieve gets stuck in the machine.
Annoying.
