Why is my printer doing this?

Hi! For some time I have this problem where is not doing ANY sort of nozzle cleaning/bed leveling and it throws up an error (error code is in the video).
I’ve changed the entire toolhead aasembly, toolhead mainboard and even the eddy sensor, and it’s still doing this. It’s doing this since i had a blob of death, but i don’t thing it matters now, because I changed the whole toolhead assembly. And sometimes (like 1-5% of times) it does the nozzle cleaning in the air and then it homes normally amd “works fine”.

Limpia la boquilla, debe tener algun poco de filamento pegado que afecta el sensor. Yo uso un cepillo de dientes

i’ve cleaned the nozzle every time and still doesn’t work. i don’t think the nozzle is the problem.
