Hey folks, been using Oscar for slightly over half a year now. Got couple questions about the machine and I'm not sure if those qualify as issues.

I live in China so the water is really quite hard. I have water filtration going on but it's more just purifying the water than softening it.

Anyway, I try to take good care of it (backflushing every week, cleaning the brewhead etc).  I have not descaled it since only bought it half a year ago.

Been experiencing few things:

  1. Every time I turn on Steam, there's water accompanying steam. Never just steam coming out.

  2. The moment I turn on steam, the boiler indicator will come on.

  3. I notice water stains beneath the machine. Not sure where it's leaking.

Any advice would be great. Thanks!

elektro

1 is boiler level probe clean and shinny ?
should be some water at first
purge line before and after steaming

2 after a few seconds normal

3 adjust exhaust from 3 way
not  too much water in drip tray
stains around feet and front right side , adjust 3 way exhaust
stains in front water from group down the porta filter  down the curved front edge
stains in middle in the rear  more serious investigation needed

remove top look around for discoloration
bright light and mirror helps

I agree, a bit of water is normal when you first start steaming, also the heater coming on is to keep the steam going.  Both things are normal.  Check the Boiler water lever probe as suggested to see how clean your boiler is.  And go to the link given as it is very good and has videos. You might want to start using softened water, at least to cut down your tap water hardness.

Make sure you are not over filling the tank and getting drips that way.  Check the water spots by drying the machine and then putting dark paper under it and checking for where the drips come from.
