I don't know if this is the same machine as the one in the listed on the FixYa page, but it looks like the one in the picture. Anyway, mine isn't working. The motor operates, but the shaft doesn't rotate. Any suggestions?
There are a series of gears between the motor and the shaft. Replacement parts are avaialble ad cafeparts.com under ascaso ibertal grinders. You will need to take the grinder apart to find the problem.

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.
I've long ago lost the manual that came with my grinder (I actually don't remember if it even had one), but I don't think it listed grinding times. You just grind a few seconds and check, then grind a little more if it's still too coarse. Unlike a burr grinder which is adjustable, in a blade grinder the same grind time may result in different consistencies as you change beans. By now I've just learned how long to hold the button for the different beans I buy, and the first few times I try a new blend or varietal I have to adjust the time. I think you'll just need to experiment and then you'll know what works best for your tastes.
Relax and be patient, problem is evident and it can be solved. you
will need one key for releasing oil filters(borrow from your mechanic but it is good to be 3 legged one)
Detection of problems:
You have old burrs and they
chew coffee, they don't cut grind any more. Because of that coffee is
overheating = burning(after that you have very bitter espresso)
Upper holder of burrs is jammed
and it needs to be released and removed for cleaning.
Remove hose and dozer
cover, jam the blocking pin in open position (to not block the burr
holder), take the oil filter key and input it in burr holder, start moving
left and right slowly
When you see that you can move
the burr holder than check again blocker pin and roll against fine
grinding, to release the holder. do not go more than quarter of
revolution, you can break the block pin with filter key leg.
Replace the key and continue
When you once get it out you
should clean very around grinders and all the place from coffee.
Remove the block pin and the
spring below it
Screw the holder in place and
be sure it goes inn easy
NOW IF YOU HAVE NEW BURRS YOU
CAN REPLACE THEM
In case you don't have than
measure the diameter to be sure what you are asking for.
Assemble back the grinder and
test it with old ones once(might be you set it too fine and that is the
reason for burning)
PS. do not hesitate to
ask me for further instructions' such is burr changing.
If you only got the lower burr it won't work. They should be matching burrs.
If you don't do it right, you will damage the grinder. You need a #10 Torex bit.
Insert the bit into the screw in the middle of a very clean grinder. Turn clockwise to loosen. Once the screw is out, pull the burr out, but be careful. There are ball bearings and springs under the burr. Make sure that everything is clean before reassembly. There are 3 holes in the bottom of the grinder. The springs go into the holes first. Then the ball bearings set on top of the springs. Place the new lower burr on top of the springs. A washer and the corkscrew go in next. Insert the screw in and with the bit in place turn (with a little down force) clockwise until the screw drops into place, then turn counterclockwise. It should turn fairly easy. Once you start putting pressure on the springs, try to turn the corkscrew. There is a notch that it slips into in the bottom of the grinder. Once it locks into place keep turning the screw until you start to turn the burr. That should be tight enough. Now reassemble the top burr and adjust.
The Krups Burr Grinder GVX2 featured in the picture is not a coffee maker, per se, it only grind coffee beans to use in other coffee makers. It is a lousy machine, and I would recommend returning it or not buying it. DO NOT PUT WATER INTO THIS MACHINE. It will cause electric shock.
rotate the knob to try to get out the upper holder of burr. if it does not rotate than disasemble the knob and the gears(plastic big one is attached to upper holder of grinder, the other is together with knob.
tru to rotate it manualy, with help of extra srews puted in gear holder holes.
when you get it out, carefuly clean it, look for metal parts and stones(wich sometime comes with coffee)
turn on the grinder and attach gently one marker to lower burr during spining. after you stop grinder, look if it is perfect circle marked in burr. if it is not than marked side is higher. you should consider getting it ok by putting adhesive paper under lower burr and check it again.
