I have noticed something a bit odd with the profitec pro 800 last two days.I pour my shots and go to steam some milk.
As normal I bleed any of the wet steam/condensate in the steam wand for maybe a second or two until it looks dry enough. Then cut it off, insert the steam wand in the milk jug and turn the knob back on to get the steam going. The last two mornings however a whole bunch of what looks like air bubbles have formed at the top of the milk jug. Almost like I got a straw and blew a few big bubbles in the jug. The milk looks more like bubble bath water - maybe the bubbles are a bit bigger than that, the size of a 5c piece?
After maybe 2 seconds they seem to stop and the milk begins to swirl and froth as normal.
Doesn't seem to affect the final outcome of the microfoam other than I have to work a little harder to make sure the big bubbles disperse and get mixed into the vortex. But I am a bit perplexed why this is happening all of a sudden?
The same 3L milk I have been using for maybe 4 days to a week so shouldn't be that.
It seems like there is excessive air in the boiler somehow. Anyone have any experiences similar or any reasonable guesses what is going on?
Cheers,
