Question about Baratza Virtuoso Electric Grinder

2 Answers

Motor revs but grinder does not engage.

Motor revs fine, but grinder burr does not engage, draw beans down, and grind them. It worked fine for many years. I ground cleaning beans through the machine and then it stopped engaging -- or engaging regularly. Occasionally it will engage, turn the burr momentarily and then stop.

    My Virtuoso is also revs but does not engage. If I twist the lower burr clockwise it will engage but then will soon stop again. Could be something to do with the safety feature that stops the burrs id something is caught. It is supposed to activate thermally if the motor heats up. I don't see an obvious fix for it and am about ready to splurge on a Mazzer or Macap both of which get great reviews.

Hi,
I am what you would call an expert when it comes to Baratza repairs.
The problem you are describing is not an unusual one. It sounds like the main drive gear has been stripped due to something foreign (likely a stone) sneaking into your grinder with the beans. It would have jammed the burrs, and because of the powerful torque from the motor, the drive gear has been stripped so it will no longer (or rarely) engage the burrs.

To solve this problem you will need to contact COAG Ltd (if you live in Canada) or Baratza if you are from the US. If you machine is still under warranty (less than a year old) this repair will be free of charge and you shouldn't be parted from your grinder for long.

I hope this helps anyone who stumbles upon this and finds themselves with the same problem.
Kind Regards
Emily

  1. for PORFLANO : your grinder's axis probably have security spring for avoiding further destruction you should open it and pay attention to spring, change it if it is broken.
  2. JAMESEIME& BARON check the axis before closing the grinder motor, are thay attached good to lower burr. be sure they are.

Bunn g3 commercial grinder


Humm, G-3 grinders. Okay what common problems I've come across:
* Wrong setting for grind on label. Usually means worn out grinder burrs. But this does not happen often unless you are using it to grind commercial amounts of coffee? It's a retail level grinder meant to be user friendly and simple to use. Say grind a bag of beans once every 10 mins or so even with customers lined up to grind there own. Running a G-3 constantly is usually done by upcoming coffee vendors whom are using it for small flavored bean batches. But expect the burr plates to only last 3 to 6 months. We used to change it every month till the boss bought a bigger pro grinder. (whew!)
* Out of calibration (for grind) This usually happens as soon as it's installed. Either the grinder got banged (Dropped?) around or the lock nut was not tighten down. If caught quickly then it's a simple adjustment. Left unchecked will wear out the burrs or crack the plate.
* Trips out breaker. This is common at retail stores as it's located in a shelf rack that really does not have the required outlets. Many times there is a brewer(s) connected to the same line. It only trips out when one or both brewers are heating and the grinder is running a very fine grind.
* Trips out breaker when grinding espresso or very fine grinds. Worn burrs or slim chance the grinder was miss calibrated (but you would catch this when first installed)
* Shocks the customer. Dry climates or heavy air conditioning will build up static electricity at the chute. There usually a small chain attached to the chute to prevent this. Attach a SHORT metal chain or thin cable to the metal case of the grinder and add a metal clip to attach to the coffee bag. Many use a chain and clip just short enough to keep the bag positioned under the chute. Note many coffee bags come with bag clips. Just make sure the clip and chain can't get stuck in the grinder.
* Not working. This is usually the on/off switch as it gets beat up the most. There is sometimes a safety micro switch under the chute to sense if there is a bag there. I've found may have been defeated.
* No power, check cord, breaker (GFRI) outlet, Plug prongs if broken off or bent.
* power but no motor hum. Tripped thermal breaker (usually a red button on side or back. Some models may have it inside on the motor itself. Call for service to check.
* Turns on but loud hum (may be hot too). Burrs stuck. This could be from adjusting grinder while grinding beans and adjusting to a fine setting. Grinding finer slows down the beans feeding the burrs. Large settings flood the burrs with a lot of beans. Adjustments are usually done when the grinder hopper is completely empty. If loaded and turned down from coarse to fine grind the beans already in the burrs get crushed and stuck between the plates thus locking them in. It may be possible to clear the hopper and open up the grinder to its coarsest setting to jog out the crushed beans. Otherwise call for service to have the burrs cleared manually.
*Finally check with your vendor if your still having problems.

My Saeco Odea Go coffee machine grinder screw rotates with on beans but does not rotate when beans are added. Motor sounds like its working.


There are different possibilities for your problem. First the motor might be damaged and is more weak than before that is why is stop when it need to grind beans. In this case only with replacement motor can solve the problem.

Second probably due to long use of oily coffee or low quality coffee beans or other reason there are coffee grounded in the grinder that become like rubber and does not leave the new coffee to pass through grinding burrs. For this either you have to dismantle the whole grinder and its burrs and clean them with brush or you can use a new magic product that you can fin in eBay it can clean automatically the grinder in 30 second see it at the link

You can try the above fist and you may solve the problem in minutes if not then you can proceed with the replacement of the ginder burrs or motor.

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.

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.

Why does ground coffee not go thru shoot


If using Beans; it is set to fine and due to static it sticks - OR you have a blockage..

If you are putting ground coffee into a grinder; the static will be a bigger issue and in addition there is no weight from the beans to press the grinds into the burrs. A bean grinder is not ment to grind beans that have already been ground.

Get a better grinder and do not buy supermarket beans.

I am guessing the burrs do not turn. If so, tho rare, a foreign object might have entered burrs and jammed it. Happened to me once. Small stone with beans.

When grinding coffee beans the grinder is not dropping the beans into the grinder part. I have to stay and shake or bang the grinder on counter to get the beans to fall through.


you must screw off the burr holder plate screw (in center) you will order one special screw, drill shaped, when the burrs roll it will mix and take down the coffee beans. That is solution i applied to many grinders. PS: beware the direction of burrs must be coordinated with new screw.

As I can see, what happens is that some coffee grains stucks in the way from the upper pot to the grinding wheel. This is not something usual, but possible if coffee grains are too big and are placed across the entry of the mill. Try cleaning more deep with some old toothbrush. Look for a clean and even surface of the duct.
Other cause might be a loosen mill hub/grinding wheel off the motor shaft, which would require dissassemble of the appliance to be repaired.

I would suspect a log in the outlet shute where it goes into the grinds hopper. Clean it out and then turn the hopper to the coarsest setting to clean it out all together. Coarse grinds are a very good cleaner.
