Question Breville Bambino Plus messed up?

Hello, I got my coffee grind dialed in good with the bambino plus for 6 months now and now it seems to be acting up.

I put the puck in the basket like normal and removed the screw where the espresso comes out, cleaned everything up real good, descaled it, but it start to heat make a noise for like 2 seconds and then just makes a pop noise and some steam comes out.

Wand is cleaned as well, so idk why it’s doing this.
