My Solis Maestro takes a long time to grind and no longer grinds for espresso. How do you remove the burrs to clean them? Should they be replaces?

Yes the burrs will wear out. They can be replaced. To remove the outer burr. Twist the bean hopper counterclockwise until it stops. Lift the bean hopper out. There is a cream colored ring with 2 tabs that will lift out holding the outer burr. To get the inner cone burr out is a little more difficult. We use a vice grip and grab the burr, and lock the pliers to it. Then with a quick movement clockwise on the pliers, you loosen it. Then clockwise unscrew the burr. When you install the new burr, it truns on counter clockwise until it stops. Insert the new outer burr. Push down so the tabs will lock in. Install the bean hopper into the correct slots ( 1 large tab and 1 small tab). Twist clockwise to turn on and test. Remember it must be grinding to turn to a finer grind but can be turned to a coarser grind any time.

Not fine enough grind

This model grinder won't do espresso. There is a DIY mod available online that involves disassembling the machine, and recalibrating the burrs to produce a finer grind. I did it on mine, it was definitely better, but it's not going to get you to the coveted 30 second pull for your espresso. Search on Starbucks Barista Grinder Mod. It is a great grinder otherwise, very reliable.

Oily beans seem to have clogged our coffee grinder up. What can we do?

Rotate the bean hopper counter clockwise until it stops. Lift it off. Remove the outer burr with the 2 wings and clean under the burr. Clean the opening going to the chute for ground coffee(inside where the burr was).
Install the outer burr. Install the bean hopper. Rotate the bean hopper to the French press grind (coarsest) and operate the grinder. This will clean the burrs and the passages. If it starts to clog, repeat the last part to clean the burrs and passage. It must be grinding to go to a finer setting, but you can go to a coarser setting any time. Another thing. Turn the grinder upside down (empty) and rotate the bean hopper back and forth to clean the threads of the adjusting burr..

My Solis Maestro grinds but produces only about

I would say that your grind adjustment ring is broken inside and needs to be replaced.

Why is the grind from my Breville BCG450XL in the finest position coming out like a drip grind with a fair amount of dust mixed in? I have an old Solis with exactly the same conical burrs which is grinding...

The Breville was designed to be used with Pressurized Portafilters, which most Home Espresso Machines have. These filters use a courser grind, so when it says Espresso on the Breville, it's really closer to Drip. The Turkish setting is barely fine enough for Espresso. There is a limiter on the Breville that prevents the user from going any finer, if you crack it open and remove the limiter, you can go as fine as the Solis. Becareful though, the burs can come so close to each other that they can chip and break.

I've been having the same problem. I would clean out the burrs and it would get clogged right away. But I found that at the top of the chute where the coffee comes out that there's a flap type device. Mine was clogged with coffee. When I unclogged it it would swing freely. That seems to have helped. You need to use a skewer or long toothpick to clean it and free it. Use a flashlight to see the flap. It looks like it has a weight attached to it and probably swings back and forth as the coffee is ground.

The burrs need to kept clean otherwise it will create a lot of dust and jam it up. This is aggravated with oil coffee and flavored coffee. Thoroughly clean the burrs and chute.
