    Coffee is much better. New pump sounds are much better thanks Jackster [emoji106]

    I think the pump was trying to rotate itself in situ

    Handy access panel on bottom of machine and easy access via side panels meant it wasn’t too much drama to change over to new pump.

    These Ulka pump pressure/flow rate graphs may be useful.

    Replacing a Nuova Simonelli Oscar II pump

    Started up Oscar II yesterday morning and could instantly tell the pompa was not well. Noisy as anything. Well, extra noisy with rattling sounds instead of the normal noisy Ulka pump vibes.
    Fortunately I have a spare Ulka EX5 ready for this day.

    Pressure is definitely less based on more watery liquid produced but that may also work with the new research. Sadly probably only 1-2 bar.

    Anyway, will open up the case and see what shakes loose. May the Coffee Snobs gods smile on this machine.
Working...
