Brew group not aligning well

Hello,

I have a Saeco Incanto HD8911.
For a long time it had dry coffee powder falling around the brew group and under it until it fills the little tray under then blocks the full movement of the brew group which makes the problem even worse.

Today after cleaning everything I had the idea to check if between coffees the brew group was going back to it's normal "standby" position, I placed it as it should perfectly aligned but after it did its cycle I noticed that the moving part that get filled with the powder is misaligned of 1-2mm with the moving funnel above and it leaves an opening where the coffee can fall.
If I push it I can move it in it's good position without any effort.

The brew group is perfectly greased moving very freely si it seems the problem is that the motor doesn't move it to the position where it should be.
Is there anything that can be adjusted/fixed to have the motor moving this part to the right position?

Thanks

No.
