  • Video showing installation of the silicon piston seals

    • Thanks for the link, Beanz.

      You have inspired me twice....the first time was to order some of these seals for my CMA lever. They arrived over 2 weeks ago and have just stayed in their packet.

      This morning was the second time. I watched the youtube video on seal installation and just took the plunge and opened the packet.

      Installation was dead-easy. I replaced the p/f gasket at the same time.

      It is interesting that the fellow in the video (Was that Paul Pratt??) recommended only enough Dow 111 to give each seal a shiny appearance...no more.

      He said that "the water will do the lubrication for you".

      Is there a recommended lube frequency on the silicone seals?

      Thanks, Beanz!

      I will pull a few shots later in the day and report back..

      • Very keen to hear how the seals go Paolo!

          All good, Sniff!
          Made a couple of killer shots with my Quickmill Achille with the silicone piston seals and portafilter seal installed. It is such a beaut machine that deserved more praise when it was first introduced to Australia IMO.

          I can't report that I can definitely "feel" any difference with the silicone piston seals but the silicone portafilter seal feels better locking in than the rubber one did.

          Call it piece of mind at the very least.

          (It's funny how I can take longer putting a job off than the job actually takes to do.)

          • Just a follow up to the initial review after using it for about a month.

            Noise on start up:

            The machine was making a low whining noise on startup when the boiler was getting filled. I eventually fixed it by adjusting the switch over valve. This is the manual valve that you have to turn to select between tanked or plumb configurations. Even though the instructions specified that is should point full right, when I did so, no water was flowing. When I adjusted it slightly towards the plumb configuration, the water started flowing. But if I move it too far towards this position the whining noise started happening.

            Height between group head and drip tray:

            If you're using a bottomless portafilter and a espresso cup, the height of the group head requires you to be quite accurate at positioning your cup to avoid misses. I raised my cup with a small ceramic dish to help with the aim. This dish also helps detects small sprays from the naked pour.

            Steam tip:

            I struggled to make froth milk with the standard 4 hole tip on 150ml of milk. The milk would get way too hot before any foaming occurred. After 2 weeks of completely disastrous frothing, I switched to a 2 hole tip. This made a huge difference.

            Profitec 2 hole tip:

            My 2 hole tip didn't fit as flushed with the teflon tube. This caused the wand to get quite hot. I fixed this by adding a few rounds of teflon tape around the tube before screwing in the tip.

            Conclusion:

            I'm really enjoying a lever machine. All the pressure profiling I've always wanted but with next to no electronics. It's also very easy to clean with no back flow mess. The Pro 800 is a solidly built machine with minimum flexing during a pull. However it does take longer before you can pull the portafilter out for the next shot. You can speed the process up a bit if making multiple shots but prepping another portafilter while the current pour depressurises.

              Have followed suit and installed the cafelat silicon group seal and piston seals on my Ventus. Even if they don't last much longer than rubber ones, the ease of putting them on is a big plus. Also gave everything a good clean.

              The coffees this morning were good, the lever action seemed a tiny bit smoother and the shot volume was unchanged.

                I don't find recovery time to be an issue personally. Testing showed recovery time of about 3 mins after a shot.
                Also, I find the engineering thermal sticker on the group excellent. I use it as a heat up indicator when doing a speedy machine start up (using flushing) as well as when checking for cool down after a shot.
                Keep enjoying

                What I meant was the time for the portafilter to depressurise. It's easy to tell with the bottomless, there's always little bubbles of activity when there's still pressure. I've pulled the pf out a few times a bit too early and made a massive mess! Not to mention the scary pop from the pressure. Won't be doing that again.

                  • A 'trick' for lever users - if you're in a hurry for a second shot, pull the lever back down very slightly and then remove the pf. Voila, no more residual pressure! 3-way-valve is so overrated.

                      That's an awesome tip. I was envisioning 2 group heads to cope with guests.
