I'm beginning to understand why you picked your username.
Maybe just instal your restrictor when it arrives, and take it to a shop if you still have issues.

Oscar II - water flow stops while flushing

Jackster is saying that you aren't testing at the right place, not that you don't have a problem

Thats weird because I asked a friend - oscar II owner and with his machine the water flow never stops, he even sent me a video showing that.Originally posted by Jackster View PostMaybe, your pump is fine, and the restrictor is doing it's thing, and your flow numbers are correct at your test point.
On my machine if I do a long flush, afterwards there isn't enough pressure in the system and sometimes it can take 5-10 seconds till it starts flowing again.

I see your video. Not sure where your test point is.
i see it's a plastic pipe, so can assume you are either before or after the valve I indicated previously.
you need to keep testing back closer to the pump. This will show you where the restriction is, or if the pump is bad.
I see no part on the diagram listed as a gicleur. So I don't know what you have ordered or where it goes. Traditionally (and in the case of the 2 gicleurs I bought) they fit into the hx pipes that feed the grouphead.
Though, I am not familiar with the calibrated orifice at item2. Is this the thing you are calling a gicleur?

Tank was more than half full, tested pump rate after 0.7 gigler:Originally posted by Jackster View PostWhat happens if you test pump flow directly out of the pump? Say at the pipe on bottom of that valve.
It kinda looks like you are trying to pump air. My machine needs around 1/4 tank minimum or it seems to suck air.
About 300ml in 45 secs. it took 55 seconds to fill the 350ml cup.

I have disassembled the one-way valve you marked and also the group head, and inspected the gicleurs...
there was some scale and rust but nothing too dramatic so I don't think that's the problem
anything else to check?

Thanks for the replies!
Is the green plastic check valve located where I circled?
For sure the pump gives 300ml in 30secs, when the boiler gets to pressure the water quickly gushes ous 300ml even in less then 30secs but then the flow slows down and stops for about 10 secs...
Its a brand new pump and I tried to clean the orifice, but I already ordered a new 0.7 orifice with the OPV...

I have a Musica. There is another non return valve in it. I think it is just prior to the hx circuit. So the pump cycles to prepresurise the hx (through that noreturn valve with 3way closed), then cycles again for preinfusion (3way open to pf), then it starts the brew.
Not the neplax. It's the expansion valve
