S1V2 leak assistance

Post by Chura »

Hi

My Vavaldi S1V2 feeling sick today, the leftover drawer filled to the top, and then I notices that something's wrong.
See attached video:
1. Brew head drops sometimes
2. Over-pressure (right ?) keep releasing water.

What can I check ?
tried back-flashing, still the same.

There is no OPV on that side. There is an expansion valve (right) and a 3-way valve release tube (left) that are next to each other. What you need to do depends on which one is leaking.

BTW: The link to the video in your original email is improperly formed so I can't watch it. Otherwise, that might answer the questions I asked previously.

Maybe now ?

its the 3way, and sometimes the group.
I tend to believe the solenoid got some dirt of coffee in it that won't allow it to close properly
Following this thread https://www.s1cafe.com/viewtopic.php?t=1221 , I tried 3 rounds of backflush with coffee clean and 3 without. still he same.

Do you think its the solenoid as well ?

It's probably the 3-way valve itself and not the solenoid. You should remove the 3-way valve and check under it for obstructions. It is also possible that there is small mineral deposit inside the valve. You can try taking the valve apart to check. That said I have had this issue with 3 or 4 3-way valves over the years and was only able to get one apart. When I did, I couldn't find anything wrong, but when reassembled it worked fine. There is just a spring and a small plastic plunger inside and I have never found a place to buy those piece parts.

Worse case you may need to buy a new valve. If you look around you can find them for much less money w/o the solenoid included. Naturally it is easier to find the valve with the solenoid included, but that will bump the price up quite a bit.

Do you have any idea where can i get the valve only ? I guess it has to be specific model to fit in the solenoid

Since you are in Israel, does that mean you have a 230V machine?

If so, this part from espressoparts.com is probably what you need. I have not been able to find an option for the S1 that doesn't include both the valve and the solenoid.
