Hi friends, I'm pretty new to the coffee community having only recently discovered the fun of pulling a perfect espresso shot.
I own an Oscar Nuova and am trying to see if I'm doing a good job maintaining it. I have now used it for about 5 months now and I backflush once every week (only pull couple shots at most per day).
I have heard that some owners decide to descale the machine. Do you recommend it and if so, what is the process for this particular machine? I don't really understand descaling and would very much appreciate any advice or guidance.

It is a pretty easy process but on an Oscar, draining the boiler to get the soultion out is a little PITA. There is a drain but you need to get to it then put that corner over a sink or something. As you face the machine like you were going to make coffee, it is in the back left lower corner. To get solution in is easy, just put it in the water tank and pull water from the tank to get it in the boiler and in the HX system.
Helen is one of our resident Oscar experts, she has pretty much hot rodded her machine and knows them inside and out. I just am remembering from about 5 years ago when I had an Oscar.

Feed the newbs, starve the trolls and above all enjoy what you drink!

I would not bother unless it is a year old and your water is hard. If it is soft I would do it every other year. Mine was 2 years old but not doing much and I used it a year with soft water so I consider it "used" a bit over a year and the insides were not bad at all. I will probably take it down to the bones every other year.
Buying advice: GRINDER GRINDER GRINDER. Don't cheap out on the grinder.
