Thank you for your reply. I have no problem handling this repair, but I'm a little worried about the mineral deposits around each fitting and whether there will be corrosion that causes further damage when I attempt to unscrew and retighten them. Is there anything I should order from CC other than t...

I have an old S1V1 I've been using on and off for the last few years. It was manufactured in 2006 and probably had a hard life with the local water supply before I acquired it. I descaled it when I first got it, and I've since stripped and cleaned most parts of the brew path at various times, and it...

Bob_McBob

Today I swapped the vac breaker and rinsed out the steam boiler pretty thoroughly with siphoning (I gather the previous owners never used it and it was a little funky inside after descaling). Got it set up on the kitchen counter and pulled a few shots earlier this evening. It seems to be running pre...

Bob_McBob

It does seem to come on in a similar way to the recordings from the thread you linked. I could live with a whooshing like that, but I'm still getting the awful screeching noise from my videos with the previous pump. I tried damping the long tube with my hand and some rubber material, but it didn't c...

Bob_McBob

I finally got around to installing a new pump in this machine. I adjusted it to 9 bar with my portafilter pressure gauge simulating shot flow, and I've been able to pull some decent shots, so I assume it's installed correctly. Unfortunately, I am still getting the screeching noise from my videos und...

Bob_McBob

It sounds the same when I'm pulling a shot. If you look closely in the video, you'll see the brew boiler isn't actually up to temperature, so it can't be flash boiling. It's a very loud squealing noise that definitely isn't normal. CC told me they think the pump is shot.

Bob_McBob

I checked again and it's basically all a light grey powder, so it must have dried since I took it apart. The pump shows some signs of moisture at the bottom, but the residue only extends as far as the little drain hole inside the motor, so the motor itself will be fine once I wipe it out. It doesn't...

Bob_McBob

I think the squealing is caused by a bad pump. I tried adjusting the OPV, but it made no difference. I tried descaling the machine with the same result. I removed the pump from the motor and found some damp black/white residue and spots of rust on the shaft, so it must have been leaking a bit. Lucki...

Bob_McBob

I went to Home Depot, but as usual they either didn't have the correct parts or were out of stock. They didn't even have 3/8" OD tubing! I transferred the hardware from my E61 portafilter pressure gauge and found that the pump is only running at 6.75 bar off the Flojet. I won't bother to adjust...

Bob_McBob

I also wondered about cavitation, especially with the reduced flow rate at the end. I've never had any experience with it before, and I can't find a recording of what it sounds like in an espresso machine. It seems to be described as either buzzing or squealing. I just want to be sure it's not some ...

Bob_McBob

You might have to turn up your sound, because the Flojet is fairly loud. The first water draw sounds normal. I'm talking about the squealing noise the second time. It even looks like the flow dies down before it should.

The parts from CC arrived on Tuesday, and the screw from EP showed up today. Got it all assembled and installed just now. I was surprised by how poorly the gasket fit until I read you need to let the machine heat up before it will seat properly. Tried that, and the portafilter locks in nicely at 90 ...

Bob_McBob

After comparing the screw installed in my machine with photos of the regular screw online, it would appear that the two are completely different. The standard screw is a cap screw, but the pod adapter uses a flat socket cap screw like this: http://sig.fortepianos.com/41JTTGT7ZGL._SL500_.jpg EPNW is ...

643 VITA TE 5X25 4571 VITE INOX TS 5x20 What's the difference between these two screws, other than the length? Will the 20mm screw work with the regular dispersion block? Unfortunately EPNW is out of the 25mm screw for two weeks. I ordered the thin-style dispersion block, which is 4mm shorter than t...

Bob_McBob

Well, everything is ordered, so hopefully I should be pulling shots by next week

Now to build a portafilter pressure gauge...

Bob_McBob

I did hear back from Jason, actually. $18.50 for the dispersion block. Where on earth did that $69 price come from?

No re-build parts available for my Duetto steam wand, unfortunately.

Bob_McBob

I have to believe that Chris Coffee can do you better on that dispersion block. If you look at the pod kit, it is only $60 and it includes the screens, screw, dispersion disk, and basket. If you buy just the screens and basket they are $20 for both. So there's no way the dispersion block should be ...

Bob_McBob

I heard back from Astra, confirming that yes, $69 is the correct list price for the dispersion block. They also don't have it in stock. Still no word from CC. I am going to place an order online and note the extra parts I need in the comments. I'm still trying to figure out a part for my other machi...

Bob_McBob

Trying that next. I feel like a bit of an idiot sending the same e-mail over and over again. I should probably just do the online order and add the unlisted parts I need in the comments field. I hope the dispersion block is still only $20.

Bob_McBob

E-mailed Mary again, and I still haven't heard back. I guess it's time to give them a call. I really dislike making such complicated orders over the phone, though. Astra never answered my question about the oddly high dispersion block price, either. I'm not having much luck getting this machine up a...

Bob_McBob

For future reference, these are the parts for the pod adapter kit. Note that the pod screw is different from the standard one, so I'll have to get one of those as well. No word back from Astra or CC, unfortunately.

Based on a more general La Spaziale parts catalogue, it seems to be the dispersion block used in the professional group.

Bob_McBob

I e-mailed them to ask if the price is a mistake. Looking at the parts diagram, there is a third dispersion block option (part #641) that also appears to be used in other machines. What is this for? http://sig.fortepianos.com/s1groupparts.png 641 PORTA DOCCETTA (???) 1941 PORTADOCCETTE IN OTTONE H=1...

Bob_McBob

Well, I already own a Vario, and I don't think it is going to stay in rotation as an espresso grinder if some other doserless options I have on order work out. I've never used it for anything else, but I suppose it would be silly to sell it and buy an enormous Bunn if the quality as a dedicated brew...

Bob_McBob

Is the Bunn in stock form a worthwhile upgrade over the Vario for regular brewing? I am interested in getting a high-end grinder for pourover and cupping, and the bunn G-series is relatively easy to find within driving distance.

Bob_McBob

If you just generically used that Contact form, you should try again directly sending an e-mail to mary@chriscoffee.com I sent it directly to mary@chriscoffee.com on Tuesday around noon, because I've ordered from them a couple times already and know the drill about Canadian orders. Got the prices f...

Bob_McBob

Thanks, I'll e-mail them for a quote. Do I need the paper shim shown in the diagram (part #9)? Also, is the bolt that's currently installed okay for the regular dispersion blocK?

Bob_McBob

I e-mailed a couple days ago with my list of parts to order and never heard back, so I guess I'll be waiting until Monday now, and another week or two for shipping :-( I asked a couple of Canadian La Spaziale dealers about parts. One of them doesn't sell parts, and the other (Caffe Tech, which impor...

Bob_McBob

I would normally hold off on ordering parts and do a more thorough check, but I was already about to order parts for my regular machine, and I don't really want to delay that. I have it set up and running off a Flo-Jet in ECON mode. As far as basic operation goes it seems to be just fine. It comes u...

Bob_McBob

I recently acquired an original Vivaldi from mid-2006 that I want to test and check over before use. I haven't been able to pull a shot with it yet, but it heats properly, sounds good when running, and I don't see any leaks or obvious signs of damage internally. Unfortunately, it only came with a po...

Bob_McBob

What is a reasonable price for a basic mk1 Vivaldi in good condition? I've been checking through listings on CG, but most date back far enough that I'm not sure they are applicable.

Bob_McBob

The 9% duty on top of your sales tax kind of kills any benefit. If you get it from Caffe Tech, you only pay PST outside Alberta, which makes the Mini about the same price, and the V2 actually cheaper.

Bob_McBob

$300 more tempting

I know their price has been a lot better than any of the US resellers since the big increase, but the Euro *is* particularly low now, which makes most of the stuff they sell noticeably cheaper than last year.

Bob_McBob

It's not that I think I need two dual boiler machines. I'm quite interested in the technical aspects of making espresso as well as the coffee itself, and I love to play around with different machines. It's unfortunate the used market in Canada is so dead. For this Vivaldi, I was thinking I might buy...

Bob_McBob

Looks like $350 for the control board, and maybe $100-200 for other assorted items like the pressure gauge. This doesn't include any assorted bits and pieces like gaskets. Unless you're getting a steal on the V1, I guess it might be better to hold out for a used V2, though used machines don't come u...

Bob_McBob

This is a well-timed post. I have an opportunity to buy a good condition V1 for a pretty reasonable price. I own a Duetto, but I'm sort of curious to see how the other side lives or something ;-) I'm a little concerned that the original Vivaldi is kind of left in the smoke of the current model, with...
