Test if it now works with some coffee.

If it works, what you can learn from this is to clean the grinder regularly.
Clean by brushing the nozzle.
Or dismantling the nozzle and vacuuming the coffee outlet.
This can happen sooner if the coffee you use is very oily or if you put your portafilter too close and block the delivery passage.

If it doesn’t work and the burrs are still not spinning. The grinder could be jammed.
Don’t worry, and try the following.

Problem 2: The grinder is jammed

If you have made wide adjustments, this could be the issue.

Bezzera BB005 troubleshooting

Turn the grind setting 10 to 20 FULL rounds anti-clockwise towards (+).

Remember roughly how many rounds you made

Bezzera BB005 jammed with no coffee

Check if it starts spinning now.

Most likely, it should.

Test if it works

with some coffee.

If this works, wide adjustments on the grind setting were likely made. This could potentially jam any grinder!

Making minor adjustments at a time or adjusting while the grinder is spinning could keep this from happening.

If it doesn’t work, then bad news. It must be something else.
Most likely, something hard went in and busted something up.
Foreign objects hidden in coffee, such as nails, stones, etc. are common.

Fortunately, the Bezzera BB005 grinder is designed to sacrifice a gear when this happens. This prevents the motor from getting destroyed.

You can submit the technical support form and send the grinder for repair or inspection.
Please mention if you have done the troubleshooting.


Q: Will I have the same problem if I get a low-retention grinder?

Yes, the same problem happens to any electrical grinders. Coffee sticks and balls up at any opportunity, and making wide adjustments will cause the grinder to jam.

Q: Can the problem be fixed with the above solution?

The instructions given above should fix 90% of the reported issues.

For the 10% that has to be sent back, every piece we received to date could be repaired, thanks to the clever installation of the sacrificial gear.

Q: What about cleaning the internal burr?

The safest and easiest way is to use the Pulygrind crystals.

Together with vacuuming the nozzle, it should be clean enough.

It’s not uncommon to see customers who destroy their grinders after they dismantle the grinder to clean, so we don’t advise doing that.

Q: Can you help me clean or clear the jam?

Yes, the service can be ordered from Maintenance Service for Grinder

Service does not include any repairs, including replacing the gear assembly.

Q: Can the instructions be used on other grinders?

More or less, yes.

You might be unable to access the nozzle easily, or you may have to remove the upper burr.

Suggest doing the steps for freeing the jammed grinder first.
