Question about Solis Maestro Electric Burr Grinder

2 Answers

Embarassing but... Took my grinder apart because a oily batch of beans was clogging the burrs. Got it apart fine but now I have an extra part and I can't figure out where it goes. It's a felt band about 1/8 inch thick and about 2 inches in diamter. I can't find a schematic anywhere for this grinder. I can put the grinder back together but and the burrs turn but won't feed or grind the beans. Any advice would be greatly appreciated...otherwise I'm going to be very grumpy at work tomorrow. Thank you very much. Rich

    I don't have the same problem, but I can possibly help, since I have my Maestro taken apart at the moment.  Is it the square felt piece?  If so, it fits between the bottom housing and the black chute the coffee passes through.  If not, what shape is it?

  • richdad Jan 03, 2009

    Well it is round but doesn't fit snugly around the bottom of the hopper - but i think that's where it goes...but now even with it in place, I can't get my grinder to do more than about 6 beans at a time before it clogs and stops feeding beans...the ground and partially ground beans totally clog the burrs every time...and i have tried every type of coffee with the same results...i am thinking about taking mine apart as well...how do you remove the burrs? Not much damage I can do to it at this point because it won't grind more than a tablespoon at a time...Thanks very much for the response!

    Thanks for the help but I've reached by frustration threshhold. If anyone wants this grinder (it's about 3 years old), I'll clean it up and send it to you for shipping costs only (my zip is 21030). Just let me know.



    Thanks

Hi Yes the felt ring is a seal for the bottom of the bean hopper. I think you still have a partial clog in the outlet of the grinder. Remove the gounds cup, then turn the grinder over and there is a flap up inside. Open it carefuly and clean it out. Then reassemble the grinder and when you first grind, make it as coarse as possible. This will clean the throat of the outlet. If you start to clog, open the grind to the very coarsest grind you can, and it will clean itself.

No, wait, I found it. If it's round and is (or used to be) white, it fits on the bottom of the clear plastic hopper. Replace it and you should be in good shape again.

    Hmm... It may have twisted some, but it should fit snugly somehow.  I took mine apart last night and found only two felt parts.  The stained, white, round one that goes on the bottom of the hopper, and a rectangular one that serves as a gasket in the coffee chute.  There's also a little door up at the top of the coffee chute that might be stuck down.


    The burr cone is pretty hard to get out and is probably not worth it, but the assembly around it is fairly easy to get to.  The housing snaps to the base with two tabs on each side (and none in the back).  Pull the timer knob directly out and pry the housing free of these tabs.  Slide the housing up until the innards are exposed.  Up top, you should see the collar (which is also held on by tabs).  That's the part that has threads for moving the outer burr in relation to the cone.  The big white piece is held to the base with three screws and can be separated by removing four more.


    Before you get in there, I have two suggestions
    (1) With the hopper on, make sure it's engaging the collar and they both move together when you twist the hopper.
    (2) With the hopper off, make sure the tabs of the collar part of the burr are in the threads of the collar.  You can see this easily without removing the housing, since the tabs are directly under the flat sides of the upper burr.


    If you end up taking it apart, please don't forget to unplug it.  I'm sure you know that, but I can't be too careful!


    Good luck!

HOW DO I CHANGE THE GRINDING MECHANISM ON MY SPIDEM TREVI EXCLUSSIVE ESPRESSO MACHINE. I HEAR THE MACHINE GRINDING BUT IT'S REALLY NOT DOING ANYTHING. ANY SUGGESTIONS


When the grinder spins free and fast it only means that fresh beans are not feeding into the burrs. This happens when:
1- Grind setting is too fine and beans cannot enter the grinder mechanism.
2- Use of oily dark roast beans can clog the ground coffee chamber and preven the fresh beans entering the grinder.
3- The ground coffee chamber outlet is clogged due to oily beans or too fine coffee setting.

When you cleaned the grinder you may not have cleaned the coffee outlet to the doser on the left. You can clean the outlet to open the passage of coffee grounds to collect in the dosing device..
After cleaning the outlet, you should next make sure that coffee grounds are not packed in the doser. The doser is inside the door right above the brew group.
To access the doser:
1- Remove water tank.
2- Remove the brew group.
3- Lay the machine on its back for full view of the doser.
4- Pull the doser door open (it is like an Attic door.
5- Keep the doser door open and clean the inside with a brush. The outlet from the grinder is on the right side with a wire wiper cleaner that moves across the grinder outlet fills from the grinder. This opening.
Use a brush to clean the doser.
On the left of the doser space there is a plastic flap that is pushed to the left when coffee grounds fill the doser.
At certain distance push back (1/4") the notch on top of the flap pushes the doser micro switch pin to stop the grinder. Push the flap gently to the left to make sure that it is moving well. With each push back of the flap, one can hear the feeble click sound from the micro switch.
When the above cleaning is done, try the grinding.
If the conical burrs have not been replaced for over 2500 grinds, it is time to do so.

The above grinder and grinder doser cleaning instructions are available as download files on the following page link:

One can find many useful maintenance guides on one page.
Good luck.

Our Saeco Vienna Superautomatica sounds like it's grinding beans but keeps running until the red 'bean' light comes on and we have to shut the machine off. Any suggestions?


The grinder is timing out and stops if the beans do not enter the grinder. This happens because:
1- The grinder outlet is clogged and fresh beans cannot pass through the burrs.
2- The grind setting is too fine and helping clogging in the grinding chamber or the ground coffee outlet.
3- Operator may have been using dark roast oily beans. Like it or not, the dark roast oily beans do not make stronger espresso. Please stop using such beans in fully automatic espresso machines.
4- The grinder has already made over 2000 grinds and the burrs are blunted and not grinding beans as needed.
To solve this malfunction, clean the grinder. Make sure the grinder outlet to the doser is cleaned. This outlet passage is about 2 inches or more. To clean it, lay the machine on its back (water tank side) to allow better view of cleaning the doser and the passage of coffee from the grinder to the doser. Use the link below to find instructions for cleaning the grinder and replace the burrs.

Talea ring the grinder will not stop gringing


The Talea model is with a Ceramic grinder system. This can happen when the grinder outlet is clogged with coffee grounds. Fresh beans cannot enter the grinder as the outlet is clogged. Remember, the grinder in any machine is a grinder. It does not shovel the coffee grounds out and clean the outlet when it is clogged.
1- Check if the grind setting is too fine (powder like). If so change the setting to coarse. Fully automatic machines do not need fine grind. Keep the grind fineness like the table slat grain.
2- Check if the beans are dark roast and oily. Oily beans are a slow poison for any fully automatic machine. Change the beans to Non oily medium roast type.

How to fix a bodum bistro electric coffee grinder that doesn't grind well


This can be caused by several things;
If it used to be good but is now faulty it is most likely that it just needs cleaning. If you are using beans that are 'oily' they can clog the grinder, you should anyway disassemble it and clean every year. Do not use soap and water, just brush it with a stiff brush (e.g. the stiffest type of toothbrush) and a vacuum cleaner.
There is also a possibility that something has got into the grinder along with the coffee beans that has damaged the grinding wheels; in that case you need to replace the wheels.

Have a grinder and it is full of coffee and stuck. It seems the beans were more oily and now I am trying to figure out how to clean it out. Please help


  • Try to grind all the beans through.
  • Put some uncooked rice inside the hopper and grind it, it is very good at cleaning if you don't have Grindz. Get Grindz if you can to grind and clean the burrs.
  • Try to take the grinder apart and brush off and clean off the burrs by hand.

Cleaning burrs of oily residue


Hi
There are many ways to clean oily residue from your burrs. You can order a grinder cleaning tablet from online stores called Grinds by Urnex. Some people use white rice but if you don't get it all out you will have rice in your coffee. You can take them apart and clean them manually but if you don't reassemble it correctly you will not get a good grind. I think the easiest way is to get some cheap light roasted beans ( doesn't matter if they are old ) but never use shiny beans because shiny beans have lots of oil.
Set the grinder to a very coarse setting, on a Rocky 7 higher that you currently use. You can turn it to a larger # any time but it has to be grinding to turn it to a lower #. Pour a cup of cleaner (beans, or rice) into the bean hopper and turn the grinder on. Grind the whole hopper through the machine. If you use grinds just a couple of #'s higher is all you need. Once you have cleaned the burrs you will need to grind some of you beans to purg the cleaning debris for the burrs and chamber. When you see no more cleaning compound you can turn the hopper back to where it was leaving the motor run. Once you get it back test with your beans.

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..

Severe clogging


Try using long grain white rice works better than minute rise, if that does not help, then the burrs need to be replaced on grinder.

1 Cleaning brush
Prep:

beans that cannot be scooped out by hand.
Remove the front and back screws and pull off bean hopper

Before beginning to clean the grinder please be sure to turn the machine off and unplug it from the wall
socket. Grinder Tip: Using an oily bean will cause the coffee to build up quickly and clog the grinder.
Saeco recommends using a medium to dark colored bean that is not oily.
After cleaning the grinder and then brewing a cup of coffee it may take 2-3 grinding cycles for the machine
to dispense coffee.
Step 1:
Remove the black rubber gasket, then vacuum additional beans or grinds from the grinder area (Fig. 1).
Rotate the outer ring of the grinder counter-clockwise until the red line is at the 12 o'clock position (as
viewed from the front of the machine) or until the red line on the outer ring is 180º from the opposite red
line on inner burr ring (Fig. 2).
Lift the inner burr ring out of the assembly (Fig. 3).
Figure 1 Figure 2 Figure 3
Step 2:
Vacuum out any residual grinds from inside the grinder and clean the grinder burrs using the cleaning
brush (Fig. 5). Clean out the grinder coffee chute using the end of the cleaning brush (Fig. 5).
Remove the drip tray, open the service door, remove the dregdrawer and brew group. Gently pull
down the coffee doser door and brush out any ground coffee that may be inside the chute (Fig. 6).
Reassembly:
Be sure that the red line on the outer ring is still in the 12 o'clock position. Place the inner burr ring back
into the grinder making sure the red line on the inner burr is at the 6 o'clock position or 180º opposite from
the red line on the outer ring (Fig. 2). Once the inner burr ring is in place, rotate the outer ring clockwise
until it will not turn any further. At this time the two red lines should be aligned. The grinder is now at the
"0" position. Replace black round rubber gasket (Fig. 7).
Take the bean hopper container and rotate the grinder adjustment wheel to zero (0) (Fig. 8) and the doser
adjustment knob to the minus symbol (-) (Fig. 9). Slide the doser adjustment gear toward the left of the
machine until it stops. (Note: The Vienna Black does not have a doser adjustment knob. Only the Vienna
Digital & Vienna Deluxe Rapid Steam have a doser adjustment wheel.)
Reinstall the bean hopper container being sure to use the LONG screw in the back, then replace the finger
guard using the short screw in the front of the container. Once the bean hopper container has been
reinstalled, rotate each knob through the full range of motion. The grinder knob should rotate from (0) to
(18) and back, and the doser knob from the minus symbol (-) to plus symbol (+) and back.
Place the grinder adjustment knob at the eight (8) position and place the doser knob at the halfway
point between the plus symbol (+) and the minus symbol (-) symbol, or to your preferred settings.
