Already using 14g. It's a naked PF, don't see any channeling. I've researched this a lot. Have you a Pavoni too? Which method do you use? Ps: I don't actually push it down so Coffee comes out and then back up. I only push down a tinny wheanny bit until coffee starts showing. Nothing actually ends up in the cup during that stage.

Yes I'm a Pavoni owner, one I use for 3-4 shots a day and I've got another two im about to refurb (or try to).

I'm not saying you're getting channels just the Felini method can cause channeling and over extraction. 14g,15g,16g is irrelevant as it varies with the coffee and the size of the basket. My point is if you're aim is a 2:1 ratio and you're getting less than that reduce your input. Also if you're getting too much output either pull the cup away or increase the input.

Ps: this is where I've seen the technique I'm following, which seems to work rather well.

If it works well then great.

By my calculations in that video if it's at normal speed including pre infusion that extraction took 01:22 for what would be roughly 30g which seems a bit long to me.

Hello

can you post the tamper please?

i got the europiccola aswell and I've ordered IMS filters,I am now looking for a tamper but it seems difficult to find a 51.+ to fit more precise the IMS,how about yours?

Post no: 26. (example, it's not the one I have I don't think).

Mine doesn't fit the basket perfectly mind you. It's just a generic cheap version, not fancy.

I haven't looked for a more precise one yet.

Tthat will do as currently I have nothing to press the coffee with

Btw is the shower screen held only by the portafilter gasket?

did you change it from underneath?

thank you

Yes.

You need to drop the shower screen and gasket. Usually by just unscrewing holding nuts at the top of the piston shaft and pushing it down does the trick IF your gasket is not stuck and baked. If so, remove the clips and the pin and force it down. Mine was quick stuck, so I used a rubber mallet on the piston shaft as per advice on the Cicarrelli site (I think). Don't use anything else or you might damage it. Make sure you have your hand near the group to catch it. Also be careful not to scratch the group as the lever will just travel all the way and will hit the group.

I put a smear of HT silicone grease on the gasket in hope that next time the process will be much easier and the need if using a rubber mallet will not be required.

So, on another thread,

Steaming milk with the Europiccola 3 whole steam wand - Any tips or tricks?

https://r.tapatalk.com/shareLink?share_fid=6813&share_tid=44526&url=https%3A%2F%2Fcoffeeforums%2Eco%2Euk%2Fshowthread%2Ephp%3Ft%3D44526&share_type=t

After a couple of weeks with the La Pav, I complained that I couldn't get microfoam with the stock 3 hole tip. It always felt that the steam wasn't strong enough, and steaming was more of struggle rather than a pleasure. So, I followed people's advice here and went for the single hole steam tip. Amazing. The different was like night and day. Although it would take me A - G - E - S to steam, (I'm talking here 2 minutes for my box standard latte, which i usually use 250ml of milk, giving me a steam volume of 400ml. Still, I always found that, if I didn't put the single tip in the right place, just surfing at 9 o'clock and with the pitcher tilted, the results would not turn out well. If I sank the tip, just slightly, the screeching was horrible to hear.

So, I decided to check the pressure of the La Pav: first of all, however, I needed a a pressure gauge. I did not want to pay for a La Pavoni pressure gauge and adapter, and I did t want it to mount it on top of the sight glass. So, after £10 delivered from eBay, and some left over silicone tubing...

I measure

D the pressure on my machine mounted on the steam wand and adjusted it accordingly.

The pressure was set to 0.68 bar, and when the element kicks in, it was going to near 0.75 bar.

So, I adjusted to 0.8bar, and when the element kicks in, it goes to just under 0.87 bar, as shown above.

Below are the thermostat screw before and after for reference. I sadly don't white remember whether I turned just under 1/4 turn anti clockwise or over 3/4 turn clockwise. I thought I would need to break the seal (that white stuff) but to my surprise i didn't need to. Looks like it either have been tampered with before or the seal just broke off naturally.

Before:

After:

I did some milk steaming and the results were encouraging, to the point that the stock 3 hole steam tip is back in business.

Obviously I also need to consider the impact of the water temperature when brewing, so I'll report back my results.

And lastly, the La Pav filling funnel mod: bottle of Volvic, nicely cut. Fits perfectly into the boiler filling hole.

If you have an Europiccola or Professional, what pressure is your machine set to?

So, after the pressure change, this is what I can produce with the 3 hole tip (I've only used it 3 times thus far)

However, I do feel that the single tip produced better quality microfoam, even though it takes 3 times longer.
