Style EC 685.M no pressure

Hi guys,

My machine doesn't do what it's supposed to anymore.
It started with my big cup only getting half full. Then with little crema, then no coffee came out at all.
Water was still coming through the hot water outlet, but with little pressure.
I have replaced the pump, as I wanted to exclude this, but unfortunately this has not eliminated the problem.
Currently I observe the following:

1) at the hot water outlet comes a tired stream (could come with more pressure I think)

.


2) At the portafilter nothing comes out at all, even without portafilter.
3) when I unscrew the distributor I still see a "cap with spring". When I then "make a coffee" water sprays out, but obviously with little pressure, as the pressure with the distributor installed is not enough to open the "shutter with spring".
4) Basically I see air in the hoses, even when discharging hot water5
) In the water tank I see water being pumped back into the tank through the overpressure hose
.


Do you guys think it's still worth replacing the flowmeter?
Since it all started with my big cup only being made half full could this part be in the bag or clogged or calcified?

Or does anyone have any ideas based on the description?

I think it's stupid to throw everything away all the time.
If it is not too much effort I would like to do it again.

Hello Bernhard
,Have you been able to solve the problem in the meantime? My device has the same symptoms and I am a bit at a loss.
