Hello from Bothell WA, thanks for making this video! I'm working on a Strada AV 3 group and I had some questions. I've been playing with the programming and I've found just that if I program the same pulses between the three heads, that I get a different output amount. The difference without a loaded puck is fairly close (~ 1 gram of water give or take), but they are quite different when loaded with coffee (all shots were weighted 18.9-19g.) But I've seen a difference of 2-4 grams when pulling shots between the group heads. We use an auto tamper so I feel like the packing should be similar shot to shot. What factors could lead to a difference when I pull shots from the different group heads? Is it smarter to use program each group independently? (We are only using 1 bean right now, so we are only scratching at the potential of what this machine can do.) (I also imagine that there is a large amount of user error on my part as I've only been using the strada for about 2 weeks now, so it's my own ignorance, let me know!)
Hi John-Paul, thanks for your question! One thing you can try is an open flow-rate test -- run the group for 30 seconds without a puck into a cup on a scale and see what your variance is. +/- 1 gram is acceptable. If you're getting much more variance than that on the flow rate test give us a call, or call your local service provider to troubleshoot. If you're using 1 coffee, programming each group the same is probably fine (certainly simpler). You could try individually programming them to your spec rather than copying the doses across through the programming menu. I hope that helps!
@@LaMarzoccoUSA Thanks for the answer. I've done a couple tests over the last couple days and found some issues with volume between the groups. The pulses between two of the groups were spot on give or take a gram over 30 seconds but the other head was consistent in itself but off about 15% in total volume from the other two heads. We're in contact with our service provider now. Appreciate the help!
My KB90 is not counting pulses in one group. I already changed the pulse meter and pulse count stays in 0. Checked impedance in the flow meter and looks good. Could it be a problem with the flow restrictor? I mean water seems to flow perfectly through the group. Please help!
I have a GB5 AV machine and I found the machine has a flow meter Alarm.. So we decided to change flow meter of both the group.. But after replacing flow meter and impeller inside The alarm is still there... I don't know why? Can you pls help? Also , We start the express button to get shot , it's not working... All the First four button glow only buy it des not start being cycle.. Only Manual button and water dispenser button works.. Can you help me why this has happened? Anything I need to correct?
Ok, I really need help here. We just got a new PBX at our coffeshop and I am trying to program my AV to certain yield. It is all magical until I want to add pre-infusion to the mix. If I do so, I get up to 10g less of espresso in my cup. Any tips on how to approach the AV+pre-infusion programming?
Really helpful info. thanks so much.
Happy to help, Alec! :)

That mini-hand is “tare-able” 🙀
