Part detached from SUPERAUTOMATICA ECAM 23.210.W.

Hello
, I have a SUPERAUTOMATIC COFFEE MACHINE ECAM 23.210.W. In the last few days the following piece of steel fell into the container that collects the already pressed/ground coffee.

I tried to disassemble the side water container + the internal block that presses the coffee + the water and ground coffee collector, in order to check where it was stuck. Unfortunately, I still haven't identified where it came off from.

Can anyone help me with this?

Thank you and have a nice day.

The part sits on the power board. Is also a heat sink for a triac. Look under the item number 5213213651 from Delonghi. There you can see it.
The circuit board sits in the machine above the water tank. You have to remove the back and the right side panel.
I would also look that I can attach it again, because the triac is not cooled for nothing.
