Found this, but really no clue if it is what you are searching for: The SMD components marking codes database - Starting with 'AF'
AF71
RP500K322A
Ricoh
DFN1820-6
DC/DC voltage converter IC
PWM step-down, 3.2V±1.5%, 600mA, +CE

thank you I did not succeed to find a chip like this , I think it can be found in a lot of boards 1.9.30.231.00_v01 my aim to find out if it is connected to the grinder and maybe has another code easier to find like this.

We dont even know which board or machine type you are speaking about, so even little harder to get help here.

it is the same as this post writer mentioned just v01 this is Lyrica sup041eu but can be found in a lot of machines like minuto it started with error 1 grinder block apparently there was block of harden coffee and i cleaned the grinder and replaced the motor and grinder sensor board but continue error 1 so i think something wrong with the board .and do not have any suspicious marks on it.
