This fixes almost all the "beans will not feed or beans will not grind"
problems caused by coffee bean dust packed in the burrs. Oily beans
cause this problem more fequently.
a. Pour all the beans out the top.
b. Open the settings up all the way and see what else can be poured
out. Use your shop vacuum to **** grounds out the spout and backward
out the bean bin.
c. Pour in some instant rice and start grinding. Reduce the grind to
a small setting like six and then open the settings all the way again.
(The grinder will not start at a low setting with the rice in it. If
you let it stop, open the settings to about 16 before trying to
restart.)
d. Pour out the rice and vacuum out the ground rice.
e. Adjust the grinder to your favorite setting and try a coffee grind.
Grind until most of the rice dust is expelled (any remaining trace of
rice dust will not affect the flavor of the coffee).
Great instructions, had forgotten all about using rice, but now my 15 year grinder works like new.
Note: Since I don't have any instant rice around, I found some sushi rice worked great, probably any rice will do.
This did not work for me. The weighted flap-door was getting stuck in the closed position. I've opened it up following the excellent directions given elsewhere on this site and will try reassembly without the flap-door. The only purpose I can see for this flap is to keep coffee fresh in the discharge bin. Since I never leave freshly ground coffee unused, I hope this will work. The other possible cause is that the plastic bosses just below the rotating burr have worn and do not impart as much centrifugal force to the ground beans as before.
Tried this and now my old Solis Maestro works like new

If you can adjust the bean hopper to the coarsest grind setting and try again. If that doesn't work, remove the grounds drawer and vacuum the inside top where the grounds drawer was. You have a blockage above the grounds drawer.
You can also rotate the bean hopper counter clockwise and lift it off. Remove the outer burr by lifting it out. Vacuum the grounds out from both sides( burr side and grounds drawer side) probe the opening to remove any packed grounds, then reassemble. The bean hopper has 2 tabs on the bottom. 1 large and 1 small. Make sure that they go in their respective place.
If you cannot rotate the bean hopper? Remove the beans and ground hopper. Turn the machine upside down and then gently rotate the bean hopper back and forth until it will rotate completely (270 degrees). This will shake out any grounds in the threads. Do not force it as you can break the tabs that rotate the burr adjustment.
I pried the housing off my Maestro, then pried the chute off and found the flap which I removed. Works fine now.
