  • Looking for tech or service with scace on Sunshine Coast, QLD?

    Hi,

    I've been calling around various espresso service techs on the Sunshine Coast in the hope of finding someone to run a simple diagnostic on my Rocket Giotto to see where my pump pressure and temperatures are at. I've had the machine for years but it's never been set up professionally.

    Not hard to find someone to service the machine but no one seems to have a Scace device.

    Can anyone help?

    Thanks

      I assume they’ve tried there. That’s basically our only coffee servicer here apart from some roasters that can help with maintinence

      They don’t have one? Would surprise me if they don’t

      I’m not sure, but I assume he’s already tried since he said he can’t find one on the coast, but not sure!

    I have a Scace but I am based on the Gold Coast if you were prepared to head down this way I could potentially help after the Easter hols. I have used the Scace to tune up a half dozen or so E61 machines over the last couple of years.

      That's very kind of you. Thank you. I will see how I go up here.

    Padre Coffee Roasters in Noosaville have a pretty good workshop. Been in there a few times. Don't know if they have a scace but they service high end stuff like Slayers so maybe worth asking.

      Hi Ronin no, I mean Padre They have a roastery, cafe and a sales and service department in Noosaville.

      Ohh sorry, I know. Padre got bought out by Seven Miles. Announced yesterday tompoland

      Ah did not know that, thank you for the update Ronin. Great place. Service section was really cool. You could just walk in and lust over all the cool machines, talk to a technician and get odd stuff done. Cross fingers that they keep it that way,

    Thanks for your help, but Sunshine Coast Coffee Machines doesn't use a Scace. They all seem to wing it with other methods.

      Closest I know off in Neli coffee in Redcliffe.
      They have one

    FWIW, this device looks even better: Pesado T.P.D (Temperature and Pressure Device)

      That is nice, looks like you need a separate pesado group handle though to attach it too

      I thought maybe it just screws on like portafilters on the standard thread below the handle. But if they made it proprietary that is a bit shit.

      From a business viewpoint it makes sense. The short video on the website suggests it screws in like the pesado spouts

    Yes, it looks perfect and much cheaper than a Scace. I will probably buy one, and then maybe put it up for sale here, at a discount, a few weeks later.

      And then after you Ronin, I'm next in the queue. :-)

    Would be handy to hang on to for when you do annual major servicing.
    Electromechanical devices do experience gradual wear and tear and slight adjustments from time to time will ensure that your machine is always operating at its best...

      Does that include testing equipment?

        Unfortunately it is a proprietary fitting. You can buy the device-only for $354, which will screw into one of their own portafilters. Or you can buy it with a portafilter compatible with your machine. In my case that's an e61, which would cost $400.

        I already have a thermometer in my group head, and a portafilter pressure gauge (no bleed needle). I figure I can calibrate those devices using this one.

        I will probably go in this direction, and then offer it up for sale here, say in a month to 6 weeks time. Maybe it could end up being like a rental device and do the rounds.

          Received my Pesado T.P.D (Temperature and Pressure Device) today, and have given it a solid initial workout. It came with an e61 portafilter handle. Compatible with my Rocket Giotto and so forth.

          TL;DR: it does what it says on the tin.

          Initial setup is more of a challenge than I was expecting due to the squeezy positioning of the gauges, the drain and lever. You have to figure out a few angles, but eventually it's good to go. What first seems like a massive problem turns out to be not a problem at all.

          Next challenge is the bleed valve. It doesn't give you much room between it and the drip tray, which makes sliding a cup and scales under it near impossible. I was on the verge of packing it up and sending it back on this alone until it became obvious that precise flow rate isn't as critical to the measurements as you might think.

          The theory is you bleed the valve then shut it off to measure the "pure pressure," as in the maximum pressure before your OPV cuts in using a blind filter. And then to measure the temperature you open the valve to replicate the flow rate of an espresso ~ 1ml/sec. I was able to more or less adjust it to that using a stopwatch, cup and tared scales but frankly, you can do it by eye. By now we all have a fair idea of what espresso flow rate looks like. It's somewhere between drops and a pour.

          The first thing I found was my OPV was set a touch low, so I notched it up about 1/2 bar. I'm not really sure whether you should measure it using a replicated flow or blind. They say blind. There's about a bar in it, if that. I opted for blind.

          Next, I established my group head thermometer does seem to measure the water passing through the group if you leave it run long enough.

          I haven't properly profiled my temperatures yet, or fiddled with my boiler pressures, so that's next. From what I can see it does a good job of reading the temperature of water flowing through the portafilter, but with these HX machines, it's never that simple is it?

          Anyway, I should be finished with it sometime next week, I think. If anyone's interested in buying it from me, send me a direct message. If you, like me, only want to run some tests and then move it on, then maybe you should buy it first and sell it on to someone who might want to keep it. It will be in mint condition and boxed as I received it, so I reckon I'll discount it by about 20%. If that sounds reasonable.

            Hmm, unfortunately with measuring temperatures it can raise as many questions as it answers. It appears to have confirmed I'm running a bit cold. Something I've always suspected but it's hard to tell from the group head thermometer. So I tried to raise my boiler pressure but found the screw on my Sirai pressurestat is wound all the way down and I can't budge it. Not sure whether this is a symptom of something else. As per attached.

            Any ideas?

            Also, has anyone put together a Scace workflow? As in, the steps involved in taking a reading, and then what to do with the results?

            There's a bit more to it than sticking in the portafilter and turning the lever. The residual water in the portafilter can confound attempts to get an instant read, and opening the valve to drain the unit is in effect a flush. I can't see any way around this and am in two minds whether this is a good thing as the puck will also retain grounds and cause a temperature differential between the top and bottom.

            I'm feeling like a newb all over again.

              S/Person I cant recall from previous posts and looked, but couldnt find .......
              Is this an early ECM. <2005? Or later Rocket >2006 Giotto Premium Plus?

              Ive not ever seen a Sirai fully wound down like that as such.

              What I recall is that it takes circa 1 turn on the adj screw to effect 1/4deg temp change.

              Also where exactly is the temp probe taking its reading from?
              In the Handle 'bowl' or down on the screw on manifold ?

                Machine is a Rocket Giotto Premium Plus. I hadn't realized the screw was wound down so tight until I took off the cap. I've adjusted it plenty in the past. Pressurestat is cycling normally. No leaking or hissing from anywhere I can see.

                The temp probe pokes up into the portafilter and is affected by the water surrounding it, not just the tip. Again, I don't know whether this is good or bad, but it's what happens in the real world. The temperature of the water in the puck is affected by the water already in the puck.
