Subject: Conti Club 1 group portafilter
 

Hi, I just picked up a Conti single group Club model for a song and it doesn't have a portafilter. I'm just wondering if anyone knows it the portafilters from any other machines will work in this unit. I don't actually have the machine yet (my friend picked it up for me) so I can't try the Pavoni Pub portafilter I have, but I also have access to a couple others like one from a Nuova Simonelli Club V and a couple others. Just hoping someone here knows something to help make my search for a cheap compatible portafilter easier.

TIA,
grim

Have you gotten a feel for your machine yet?
I'm sorry I don't have a PF for you, and I don't mean to hijack the thread, but I'm about to pick up one of these myself -- also for a song -- and am wondering what your experience has been. I'm a barista for a living, but this will be my first HX machine at home. There's very little written about the Club online, and all that I've seen has been mixed. Be that as it may, I found one for a price that simply can't be refused, so what the hay.
How's your working out?

nevermind.

I would guess that most 58mm PFs will fit but the handle may be in the wrong place when it is tight. Though I am not sure that it is a 58mm PF, but if it is, then apply the above.

Hi, congrats on the find! I hope yours is in better shape than mine. I have serious scale issues throughout the systems, most significantly the frozen pump. I'll let you know it goes as I have time to tear it apart. Judging from the layer of crud on the group screen (thicker than the screen itself), the bypassed power switch (Ahh, the miracle of wire nuts..),  and the corrosion that appears to have been leaking from the seams of the flowmeter, I think I'll need to completely tear this one down because it has rarely if ever been cleaned properly..Oh, well, at least it was cheap. Maybe we should share a thread about rejuvenating our machines.

I've heard mixed things about this machine also. It looks beefier than my Pavoni Pub, larger boiler, heavier overall. We'll see about performance once it's making shots. The Pavoni makes a great shot but requires lots of temperature surfing to get close to the brew temp I am looking for, so I'm hoping to find more stability in this beefier machine. We'll see...

Regarding the portafilters, neither the Pavoni Pub not the Silvia portafilter fit this machine (and they don't fit each other). The Conti portafilter appears to have different "ears" , longer and placed differently.

Hm. I'm a little concerned about the water dancing with this machine, frankly. Most of what I've read indicates that there's a lot of flushing needed to keep the temp down. Apparently they're known for overheating, which I tend to think is because of the huge boiler, not in spite of it, i.e. the boiler may actually work against stability, not in favor of it. Be that as it may, it's a lot of machine for not a lot of money, and I have to assume it packs a lot of steam power, which is what makes it a popular in a commercial environment. Home users are more concerned with nuances like temp and maintenance, though, and I am ultimately a home user... But what the hay, like I said, I couldn't pass on the price.  

Quite sorry to hear about that scale-clogged nightmare. Hopefully everything's still there underneath, once you get the grit off. The one I'm snagging is coming from a creperie in the financial district of Manhattan, which for some reason makes me feel better about the machine's genealogy. (A French machine from a French restaurant --- makes sense!). I don't know if it's been run into the ground with constant use and maintenance neglect, or if it's been well cared for; guess we'll see. It looks good in the pictures of course, and was described as a "workhorse" in "fully working condition" in the original ad. (It was also described as "Italian made," which runs counter to what I know about the Monte Carlo-based company...) However in subsequent emails the info was updated (and price slashed) because as they were "dismantling" it (un-plumbing? cleaning/inspecting? It remains unclear) the lights all started flashing at once, which made them think that something went awry with the control board, which may or may not be a major problem, but they didn't care to find out. No one has done any troubleshooting or even plugged it in since then, and so I tell myself it's possible that something in the "dismantling" process triggered a sensor somewhere and that once it's securely set up again, there may actually be no problem. Or, it could just need a minor adjustment, as flashing lights to me sounds like a potentially common way for a machine to tell you there's something wrong -- something solvable with a glance at an instruction manual. But even if I have to lay out a couple hundred more for a part of two, I'd still come out ahead.

Let's start a new thread about the Conti Club 1-group. The web could use one.

The HX flush is not a big deal and a large boiler ADDS to the stability of the machine. Due to the HX tube running through the boiler, it is the water in the HX tube that over heats, once that is flushed from the tube, all is well with the world again.

If you are finding that you need to flush more water than you would like, just drop the pressure a little. You should be just fine running that machine at 1.1 bar rater than `1.5 that is a bit on the warmer side of things. You will not miss the additional steam pressure either when working on your home coffee bar, there will be plenty to steam your milk with while at the same time, taming the machine for home use a bit.

Thanks for the tip, calblacksmith, as well as the info. I guess I was just theorizing that there would be a longer portion of HX running through the x-large boiler, therefore a longer-than-usual flush might wind up necessary. I've also read that heat from the jumbo boiler causes excessive heat in the group; I had to assume the sheer size of the boiler might have something to do with these issues. I'll be sure to try the pressure solution if any of these issues do crop up.

I started a new general thread devoted to our dealings with the Conti Club 1-group... Let's continue this discussion there, no?

Please help me figure out why my conticlub one group machine keeps demanding water when it is full thus causing the boiler safety valve to overflow? I tried turning it on and leaving the steam wand open a bit to relieve the pressure but after about 15 minutes of being powered on it clicks and demands water over andover again. I have had this machine for about 3 years (got it brand new) and it has never been serviced (nobody here in Hawaii). Is there anything I can do? I have the back flush detergent and the dummy portafilter; should I do that? Can I do that without the machine being fully heated? Forgive my ignorance and neglect on my machine; my x husband ran this cart and apparently did no maintenace to it. Please help me!
Thanks,
Mhamm

It sounds like there may be a couple of things going on here. These machines (any machine in regular use) needs to be descaled about every 6 months to a year depending on the water you feed it. This is not detergent in the blank PF (which you should do fairly often depending on your use but I would say in commercial use, once a day would not be too much) but the addition of a chemical into the boiler to remove the water scale inside the boiler, this is the same stuff that builds up on your shower head at home.

If your machine is over heating, it may be the pressure stat, this device is what controls the temp of the machine and is my guess as to what the problem is when you say it is blowing the safety valve. What does the temp gauge show, it normally should be around 1.1 to 1.3 bar, if it continues to climb and go into the red or off the scale, the heater is not turning off and that points to the pressure stat.

A build up of scale on the water level sensor probe could cause the machine to over fill too, this is also directly connected to descaling the machine.

Hawaii is large enough that there should be someone who works on espresso machines, check with coffee shops to see who services their equipment, I can tell you that the do have someone to service the machines.

By leaving the steam wand on, you are using up water from the boiler and the normal reaction of the machine is to add water into the boiler to maintain a safe and normal water level. I really think the issue is a bad Pstat and you are adding in more problems than you are solving by opening the steam wand while masking the true problem.
