Subject: Vario lately producing gushers no matter where I put the Micro
 

I have a Vario for about a year now.  For my espresso grind I have it at 2 on the Macro.   Lately I've been have bad gushers on all blends of espresso from various roasters.  I thought it was a blend problem--but it has happened on two reputable roasters' blends.   Normally it is consistent at between Q-S on the Micro & always 2 on the Macro.   Had gushers today on Q on Day 3 Post Roast--so NOT old or stale beans.  If anything, on new beans, I should easily be able to have the Micro on Q-S or even T.  Normally, as the days go by, and the beans get older; I should only have to move it to O at the highest(finest) on the Vario.  I know people say the humidity in the home wreaks havoc on beans & can cause the gushers where you have to really make it fine to get a normal result.  I have recalibrated it twice & cleaned the burrs.   I hope someone else chimes in cuz I'm at my wit's end.

I recently had the same issue occur where one day I was getting gushers out of nowhere.  What solved the problem a few days later was dismantling the grinder and cleaning the grinds on the burrs, in the crevices and the shoot.  I used a toothpick, pipe cleaner and vacuum.  It then went back to my normal settings.

I'm thinking that isn't it because I just dismantled the burrs a couple months ago and cleaned thoroughly.  I only go through 4 shots of espresso a day--so not using a ton of beans.  Plus I also use Grindz.  I'm next going to try something a little different with my dosage.

Wayne, the title is confusing as well. She must mean MACRO, not Micro. Moving the Micro 7-8 steps would have no effect.
A correct calibration on a Vario wil USUALLY place the Macro at 1 down from the top, Micro around the middle as a good starting point for espresso.
Having calibrated about 5 Varios (friends and a school cafe) the average is where I stated it to be.
She (Linda) is incorrectly calibrated. I believe I posted this on his "other" thread."
Lets see where this goes. Happy trails!
Happy holiday to all.

Okay, I know I just didn't make it up putting the Macro on 2 for espresso.  Since the instruction manual doesn't tell you where, I looked on line & found a youtube from Whole Latte Love by a couple of their techs.  They said to put the Macro down one notch down from the top.  That would be 2.   That's why I put it at 2.  I've heard people use 1 and 2 on the Macro.

Chanty, sorry if I misunderstood. So, you have the Macro 1 down from the top>
Cool. Have you performed the calibration with the grinder empty, as described in the Baratza manual, and on their website?
Your grinder might have been calibrated coarser at the factory.

First, just make sure the grinder is clear of beans, including the throat.
Then follow the instructions in the manual. It's an "ear thing!"

The older Vario did not have the Macro numbered.  My first one--the belt broke after a week--so they sent me a new one.  After a few months, the screw inside broke.  They sent me a newer (2 month or so) refurbished one.  That had the Macro numbered.  No--I am not rough with my machines--just unlucky I guess.  Yes I have performed the calibration with no coffee grinds in it.  Very careful with that!   I'm wondering if I am having more of a dosing issue than a grinder finer issue.  I'm gonna buy some beans just for trying different dosing.  I know I will waste a lot that way.

Chanty, a little different slant on the problem.  I am not suggesting that anything already noted will not address the issue.  I see that you have had the machine several years.  Did you ever adjust the OPV.  I am not suggesting that the OPV is the cause of your current problems, but if the OPV is set at about 9- 10 bar, depending on dynamic or static, the machine is more tolerant of grind. I understand that the OPV did not change itself and cause the changes that you are having, but fairly easy to set and it can help.

I'm not as savvy as you guys are on here!  When you say OPV, are  you talking on the espresso machine?  I've only had the grinder a year in October.
