The silicon tubing connecting the steam boiler to the OPV becomes very
hot when the air/steam starts to flow backwards as described. That's
why I thought it was steam. I suppose it could water above the boiling
point that then turns to steam when exposed to atmospheric
pressure...whatever it is though it is hot. I don't know if this
silicon tubing from the steam boiler back to the OPV and finally back
to the reservoir should be hot like that. Should it contain air? I
don't ever remember this when I first used my machine.
So it is likely steam, what do the pressure gauges on the front of
the machine say?
I think there should only be flow through the return hose if the
pressure in the system is over 12 bar or so. but you say that if you
release the pressure in the brew boiler, that's when the steam forms,
when there is no pressure. If you leave pressure in the system after
a shot does the silicon hose still get hot?
Which hose is the steam coming out of, the inlet hose or the blow off hose.
