Brand new, 3 way valve issue? Help!
Posted: Fri Jun 05, 2020 6:56 pm
Hi all,
I'm sure something isn't right with my brand new Vivaldi Mini (bought a few days ago from authorized UK dealer).
During a pour there is hissing I assume is from the 3-way valve and the needle won't stabilize at 9bar, it keeps fluttering. I've tried many different doses and always does the same, often not even getting to 9bar. When I used a blanking disc however the needle flutters for a few seconds then DOES stabilize at 9bar until I turn off and you can hear it backflushing.
The volume of shot even though I've tried setting to a full cup (to test) will often cut short and random points.
Is there something obvious I'm doing wrong or could the valve need adjusting?
Have a look here... https://vimeo.com/426409028
Many thanks
Mark
