Hi,

I would appreciate if smn could help with any idea why my espresso is doing this noise when I brew a coffee. It started lately and the machine is only three months old.

Thanks for your help!

Does the pump make the same sound when you draw water through the grouphead without the portafilter in place (i.e., without coffee)? Or when the boiler is getting refilled?

I'd first start my diagnosis by removing the cups and portafilter off the top of the machine and then pull a shot to see if it still exists.  If it does, take off the shell to have a look inside to see if anything is resting up against your pump.

No, it does only with the coffee and only when the pressure bar goes to 8. I took all the cups away from the top and the noise still persist.

I tried with a blanc filter, and it does the same, when the pressure goes to 8 it starts doing the tapping or knocking noise. I read somewhere that it could be the OPV.

Not sure, I will not open the machine as is still under warranty.

Thank you

Thank you! I am afraid to open the machine, I am not so good in knowing what goes inside. I will just contact the dealer.

in my opinion is the OPV as mentioned before, are you using a fresh coffee?
What pressure the gauge reaching once the sound come out?

Yes, the coffee was roasted about three days ago. It did it again when I pulled my morning shot. I will keep an eye on it, I hate dealing with this thing right before Christmas...

The gauge reaches 8 bar.

I am not at all sure how accurate my opinion is, after just hearing this over the crappy speaker in my phone, but your pump sounds like it has air in it and the relief valve will sound funny when air bubbles are going through with the water...
I assume you're using your reservoir (That it's not plumbed in). Pull the reservoir out and look at the valve in the bottom, look at the big red o-ring.  Everything look normal? Lift and lower the reservoir, in its proper position,  to make sure it's well seated. If that valve isn't properly opened by being low enough in the machine, the pump could be sucking air rather than water.
