james65477564 I had the V3 about 14 months before it was released on sale to the general public. There was apparently a slight issue with the preinfusion and low flow system. Mine never gave me any trouble, and still hasn’t. I am wondering they must have had some trouble with early units, as they sent me a complete valve system (pipes, solenoids, one way valves etc.. all assembled together as a drop in replacement)?
As I still don’t have a problem, I never bothered to change it. One time though, after not using the machine for a while it did make an odd squeal from the low flow section, BUT, I had not used my machine for many months and it had probably dried out/got air in the system.
I think if you rarely use low flow start, that might be the issue. It’s such a good function that I use it a LOT. In fact I use the paddle much less. I set the machine to give the max pressure I want and then use low flow start and sometimes a low flow finish to have an “automatically profiled shot”. I keep meaning to do a video about how I use my V3. Along with how to I set up a new machine in terms of parameters…just have not had the time to do it. I have a Black V3 Bianca, which I want to do that set up video on.
Can you make an unlisted video on YouTube and paste the link here?
