I have problems with pulling consistent shots. Machines is all OK (temp, pressure). Grinder is Baratza Vario, 1+ year old.
I tried to adjust it yesterday and have grind at MIN and still have too quick of extraction.

At this age should I replace blades? What else I should look at?

Burrs shouldn't need replacement yet, if you have an average home use... Maybe they need don adjustment. Mine did. I've got a guide somewhere... but for starters, if empty and at coarse, you start the grinder, and then adjust finer, when does the grinder change sound...? Is say it should do about coarse setting 3...

As long as you don't have pebbles mixed in with your beans, those burrs won't need replacing for probably ten years. If you figure 3#/month, that's 36#/year = 360#/10 years. Do you go through that much coffee? Iirc, the Vario burrs ought to last at least 400# before replacement is warranted.

No, not even close. Mayve 2# per month.

I think I figured out what is wrong. I didn't put enough coffee into portafilter and was tamping on edges without actually tamping whole pack. Now I ground more so portafilter is full when shaked and machine chocked, like 10 seconds preinfusion and very slow extraction. So all is well, brain fart on my part for not grinding enough.

Might need calibration. I understand Baratza stopped including the adjustment tool recently.. but if you've had it a year now you should have it. It's a small tool that looks like a heavy knob with a small hexagonal tip. There are videos on youtube that show how to adjust the burrs so that they're closer together again and can grind finer. Might work but Baratza could probably give you a better answer and they are very responsive.
