In this video we look at Nuova Simonelli's value offering to the Heat Exchanger (HX) home espresso segment. In order to give consumers a big boiler for their bucks some things were sacrificed to keep the price point down. However, there is a great set of aftermarket parts that can be purchased to allow you to make the Oscar the machine it can be.
Installed in this demo machine was an overpressure valve kit to keep brew pressure at a max of 10bar, down from 15bar supplied by the pump, an anti-vacuum valve and finally flow restrictors to optimize the flow rate through the group.
Enjoy!

I would need a video tutorial on how to perform these upgrades but videos and info on this machine in particular are rare to find. I imagine many people own Oscar 1’s and are having the same issues finding information/tutorials

Check out www.elektros.it they sell the upgrade parts and have some videos on how to install.

@@espressorestomelbourne1735 Sorry to dig this one up but I really need those parts as well: they dont have any in stock, are there alternatives (maybee from other machines or potential buylists)? Would like to get an opv, maybee a pressure gauge and if it is possible an preinfusion chamber or something similar.

@espressorestomelbourne1735 2 года назад

I used an Isomac OPV on a Oscar 2. It just needs to be between the pump and the heat exchanger. The over pressure return line needs to be put back to the intake side of the pump with a t-piece. Look for videos on Oscar II, their are similarities.

Mine is blinking the three top lights after warm up. Do you know what that means?

Does the steam wand handle multiple drinks well or is there a waiting time? Not using in a cafe but sometimes we do catering and have 5-10 drinks to make

@yassinchelh273 2 месяца назад

Where was the flow restrictor at for the Oscar I and can we see how and where did you install the anti vacuum valve, does the installation of this valve involve anything like drill a hole on the boiler etc? That flow restrictor really does make difference here, I see no more gusher flow.

@espressorestomelbourne1735 3 года назад

The anti vac installation will vary on the version of the boiler. One version it is as simple as removing a plug and then screwing in the anti vac valve. Another version, such as the one I upgraded, required that I have some T and elbow fittings. I moved the safety valve to the steam tap fitting and that the pressurestat and antivac valve on the same fitting.

Flow are placed in the inflow and out flow of the group. There are 2 sizes, one for the in and one for the out. Check out the video from Elektros: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-O1pVLvvIsec.html

@@espressorestomelbourne1735 Oh, thanks, and btw, I noticed that Oscar both 1 and 2 are 1200w heating elements, yet the power cords are 16A, that's not usual, do u happen to know why is that?

@espressorestomelbourne1735 3 года назад

@@checkwhatsleft4565 no idea, probably what Simonelli had laying around the factory for commercial machines.

@checkwhatsleft4565 3 года назад

@@espressorestomelbourne1735 Could it be for the commercial parts like Sirai pressurestat, max capacity of Sirai could go up to 30A, I saw other clips shows the same Sirai pressurestat in Profitec 500 draws up to 11A。

@chrischowfun 2 года назад

I've found the steam wand way too powerful...I can't seem to produce decent milk and I've resorted to using the one-hole tip on my old Delonghi after brewing espresso on my Oscar (which I'm kind of embarrassed to admit). Any tips for using the four-hole wand?

@espressorestomelbourne1735 2 года назад

Apparently it is a a lot about where it is placed in the jug, the size of the jug and how much you are steaming. You should have seen the art the buyer of the machine in thd video created! He puts me to shame. Its practice.

@espressorestomelbourne1735 3 года назад

If you are after the upgrade parts you will find them at Elektros : www.elektros.it/au/en/Oscar_modification_Kit/. I also need to give a shout out to www.lamacchinadelcaffe.com/ who actually consolidated an order I had with them and parts from Elektros (his mate) to save me on shipping!!! Both companies have also sorts of good parts and certainly very reasonable prices
