Gary,

Thanks for the link and the pictures. This is going to be the project for DH when he comes home. I am scared to even try to remove the sight glass cover. Mine is a newer model without the screws. Is there a way to take it out without breaking. doI gently squeeze and pull up or down?

I don't have a current machine, but this procedure from "Bong" looks good at first glance:
(I have the Pavoni plastic protector, but the protector doesn't lock in on the gen 1 sight glass mounts.)

Hey Craig,

Thanks for the video! :D

Edited to say, that this removal is a pain! What genius designed this cover?!

The sightglass cover is a $15 part. Since it's meant to snap on, snapping it off won't break it. I believe that it's worth snapping it on and off yourself to develop confidence in servicing your machine. When I had my 3rd gen machine I would use a flat blade screwdriver to gently pry off where it established its grip.

Gary,

You were right, all that needed to be done is to tighten down the lower sightglass nut and not to over tighten it.

Thank you again.

Do you guys think I should add the group head pressure gage from coffee sensor.. It seems beneficial, just not sure if I need it....

I put the BPlus version on mine, but plan on eventually removing it because I think gauges look ugly on this machine. I just want to develop the muscle memory for what 4bar, 6bar, 8bar, etc. feel like. So far, 8 bar is pulling with a lot of force, 4 bar is pulling too easy, and 6 bar feels just about right(*) - and pulling with what feels like a natural constant effort seems to lead to a declining pressure profile. I also plan on pulling with the Pavoni on my bathroom scale so I will have an approximation between scale reading and pressure reading for future reference.

I guess that the gauge could be useful in the long term for playing with profiles, but I have the Strega for that.

(* - I put an aftermarket wood Cremina lever handle on - the Cremina lever handle is about an inch longer than my gen 1 Pavoni handle so I have more leverage.)

Julia, I think you have a barista Robot. Do you use the gauge on it? Can you taste the difference when you follow the pressure gauge exactly? It's a personal choice.

Yes, my robot is the barista version and I used to use it a lot, but now usually just go by the feel/muscle memory. Usually when shots are around 6 to 8 bars with declining profile they taste great. But I am also convinced the a robot can't pull a bad shot. Lol

I'm with Gary. I also have a Robot w/ gauge and only give it a quick look to see my max pressure (usually 6-8) and then pay more attention to flow rate. On the EP, I was thinking about getting the gauge but likely won't. Since we have experience with what a good shot feels like on the Robot, it's not really necessary on the LPs. Especially if you're already pulling good shots off it! For me, a way to determine group temp (I use the Flair temp strip) affects the shot much more than differences in pressure profile.
