The reason for this is because it's dificult to split boilers with out damaging them if you don't have the experience & correct tools to do so. It is also very expensive & very time consuming. Other things to look for.
When considering a machine look for evidence of abrasion marks to the copper as wire brushes & wire wool are not needed for the descaling process. This usually means that they have merely cleaned the exterior of the boilers to give the impression of descaling. Look for green slush with a gel type appearance in the site glass or the water having a slightly green tint to it as this is a sign of the machine just having an acid flush through instead of a full descale when it really needed it. The build up of scale was to great to be removed by this milder process. Once this chemical reaction has occurred with the copper it is very difficult to remove without performing a further full descale.
I have a pin hole extendable laptop camera which can go down into the boilers so people can see for themselves. The S5 Compact Espresso machine is perfect for a small cafe, pub, mobile trailer etc. Or as a serious home machine. This is one seriously sorted Coffee machine which comes with it's own neoprene closed cell foam lined flight case.
(See photo) it has been stripped, completely descaled & cleaned. (See photos) Various Parts & rubber gaskets have been replaced where needed. Then it has been rebuilt & tested over a period of roughly 8hrs while being set up with a very expensive Scace 2 & Fluke device. The pump pressure has been set to 8.2 bar as per David C.
Schomer because I believe that this is the optimum pressure to make great espresso but of course happy to change it to your desired pressure if you wish. The dose settings have been set using the Scace device also with the temperature being set as close as possible to 203°F via the pressure stat which controls the temp/pressure on the S5 Compact.
This work was done by the same guy who designed the revolving robur machine on utube & has done countless work for Street coffee, Jones town etc. Go online to see some of that work. Although this machine has had alot of time & effort spent on it, it is not a brand new machine. It may behave like one being mechanically/electronically very good but has the usual wear & tear of a used machine to it's exterior.
I would however describe it's overall exterior condition as good. Things to Pick out are a lazy boiler pressure gauge that starts at 0.5bar but displays the correct bar pressure once fully heated up. This in no way effects the overall running of the machine.
Other things to point out are light surface scratches & scuffs which aren't that noticeable, both portafilter handle's also have scuffs/scratches to them. This is obviously a plumbed in machine so will need to be plumbed to a standard appliance connection valve via the pipe supplied.
(see photo) unless you hook it up to a flojet pump which would mean you can use the 5. Lt water bottles, great for mobile use.
Another benefit is that it runs with a standard 13A British plug which is often not the case with 2grp machines. La Spaziale S5 Compact EK 2 Group machine. 1 × double, 1 × single portafilter with blanking disc for backflush cleaning of groupheads. 1 × milk jug 1 × milk steaming thermometer. Water softening filter with fittings to fit machine & standard appliance inlet valve.If this machine goes for it's full asking price I will chuck in a smart flojet pump so it can be used with out being plumbed in. Power supply and power absorption. I'm more than happy to give you advice & tips on the using & maintaining of this machine, etc, If you feel you need it.
