Solis Maestro Plus: Grinding Adjustment does not move and can not take out Grinding Ring
Dear Tech support,
After taking of the bean hopper I can not lift the grinding ring as suggested in the manual (I do not want to force it to much with a screw driver). After cleaning and replacing the bean hopper.. the adjustment dial only moves a few centimetre, not enough to grind for espresso. Do I need to open the grinding machinery for this? How do I do this.
A 6ya expert can help you resolve that issue over the phone in a minute or two.

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.
Removal Step-1: Remove beans that are in the bean hopper without spilling them inside. (Use Vacuum). Step-2: Remove the beans container by removing 3 phillips head screws. Remove the rubber gasket from below the hopper. At this stage the upper burr will be visible. Step-3: Rotate counter-clockwise the outer ring of the grinder assembly (the ring has gears half way around), until the red mark is at the 9 o’clock position, looking at it from the front of the machine. Step-4: Lift the upper burr by using the fins that are on top. Press lightly on the doser adjustment gear, to clear it from the dose adjustment gear. Cleaning- At this stage, the grinding chamber will be exposed. Clean out any crushed coffee in the grinder chamber and the burrs. Use Vacuum and cleaning brush. To Re-Assemble Step-1: With the red mark on the outer ring still at the 9 o’clock position, replace the upper burr back into the grinder. Make sure that the red line (on the upper burr) is at the 3 o’clock position. This position will align the other tabs as well. During re-installation, press slightly on the doser adjustment gear so the upper burr will clear it as it is placed back in. Step-2: With the Upper burr in place, rotate the outer ring clockwise until it stops. The two red marks should be aligned at the 3 o’clock position underneath the doser adjustment gear. Step-3: Replace the soft rubber gasket back on the upper burr. Use the fins to align it properly. Step-4: Slide the doser adjustment gear toward the front of the machine until it stops. Step-5: Before replacing the bean hopper, rotate the grinder adjustment wheel to Zero (0), and the doser adjustment wheel to Minus symbol (-). Place the bean hopper into position on the machine, slightly adjusting each adjustment wheel as you are placing it down in the machine. Once in place, fasten the bean container with the 3 screws. Test each adjustment wheel through the full range of motion. The grinder knob rotates from 0 to 18 and back, and doser knob from Minus (-) to Plus (+) and back. Now position the grinder adjustment knob at Eight (8) and the doser adjustment knob to the halfway point between the Plus (+) and the Minus (-) marks. This will put the machine back to the factory setting. When using for the first time after adjusting the grinder, it may take more than one grinding cycles to make the first cup of coffee.
With the bean hopper on, turn the grinder upside down. Rotate the bean hopper to loosen any grounds that might be holding the burr holder. Now remove the bean hopper and try again to remove the holder. Only the outer burr comes off, this way.
I, just adjusted the the solis 167; first remove the Bean container by turning counter clockwise and the pull straight up) then remove the timer dialer (time/quantity control), then remove the cover by lifting the locking tabs (2 slots each side) with a flat screw driver. Once you removed the cover. Pull straight up the the white ring with the metal cup. Now you see a dark ring which is clicked on the with unit. When you look under the ring you an see little holes all along the white unit (that's important because you need to mark your old position). After marking the thr ring on the white unit, pull off the the dark ring by slowly pulling the ring outwards just on 2 places on the ring where there an small hole in the ring (there are 4 holes). When you turn the ring you will see 2 nobs, now place back the ring with the nobs 2 places further(clockwise) than the old position. You have just adjusted the grinding control! Place back all parts in reversed order. To place back the Bean container you must be aware that there are 2 black nobs in the machine and 2(different sizes!) on the container, they must be placed in a cross. I trust you will hav succes. Don't turn to far at once because you have now modified the machine and this could damage it! I will assume no responsibillity for damages! Masta NL
Your burr is not locked in. You need to remove the beans from the hopper. Remove the hopper. Remove the burr. Turn the grinder upside down over the trash can. Put the burr back in only make sure that the burr is down. Install the bean hopper and when you turn the bean hopper it should move the burr. Then you can adjust your grind. Make sure that the grinder is running is your going to a finer grind or you could break the grinder. You can turn it to a coarse grind any time.
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..
Hi Rotate the bean hopper counter clockwise until it stops. Lift the bean hopper out. Remove the outer burr with the wing-lets. Can go back in either way. Clean with air or vacuum out grounds. Use small brush to help clean grounds. Reinstall burr. Line up notches of the bean hopper with shell ( large tab in large slot, and small tab in small slot). Rotate bean hopper clockwise a small amount and test.
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
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).
Remove bean hopper
Remove grounds hopper
Remove timer knob on the side
Turn the grinder upside down
There are 4 slits on the outside edge.
Insert a screw driver into the grove and pry gently outward with a
little downward pressure on the outside until the side slips a bit.
Repeat on all 4 slits and the shell should slide off.
There is a fuse on the side of the motor that will blow and stop the
motor. It is a thermal fuse and should be replaced by a qualified tech.
Another suggestion is while the grinder is off, turn it up side down and rotate the bean hopper from coarse to fine a couple of times. This will clean out grounds that have gotten into the threads and it will prevent the bean hopper from not turning to a finer grind. If you start to get a clog in your grinder, open it up to a coarse
grind for a few seconds. The coarser grind will clean out the chute
and then you can turn it down again while it is still grinding.
