It sounds like there may be an issue with the grinder's programming or calibration. Here are a few steps you can try to resolve the issue:

1. Check the grind settings: Make sure the grind setting is not set too low, as this can cause the grinder to continue grinding even after the brewing process has started. You may need to adjust the grind setting to a coarser level.
2. Clean the machine: If the grinder is clogged with old coffee grounds, it may continue to grind to compensate for the lack of coffee being produced. Clean the machine thoroughly, including the grinder, and try again.
3. Reset the machine: Turn off the machine and unplug it for a few minutes, then plug it back in and turn it on again. This can sometimes reset the machine and resolve any software or programming issues.
4. Contact Jura customer service: If none of the above steps work, it may be necessary to contact Jura customer service for further assistance or to schedule a repair.

I hope this helps!

There are two heaters in the Z5.. one for coffee, one for steam.
Sounds like you have a fault with the steam heater.

simply you screw until you hear metal sound of burrs touching each other. Than:

Grinding setting is one simple operation but requires bit patience:

1. Turn on your grinder and continue setting to fine while burrs are spinning, you stop when you hear metal to metal touch sound(burrs maximally closed finest grinding)
2. From that point go back quarter of revolution and mark the spot where you stopped with marker to body of grinder and setting plate with one line
3. Grind little amount of coffee only to fill one sector of dosser than test it at your machine (if it leaks too fast and with yellow color of cream you should go to more fine>><< if it does not leak from the filter holder or it leaks very slow you go to in opposite way.
4. You test grinding few times bit after each reset of plate grind little amount and take that in one other pot (that will provide to have pure new granulation)

After setting measure the grounded coffee that comes out from dosser it should be about 7 grams, better measurement you can get if you measure 10 doses in one place because you don't get never same amount from 6 sectors of dosser

PS: the pump pressure of coffee machine should be from 8 to 10 bar and steam pressure should be from 1.1 to 1.5 bar> depends on type of coffees you use.

First, have you tried adjusting the grinder to the finest setting, if yes and you still have the same problem the grinder needs adjustment, either the burrs are dull or the grinder needs to be set.

Have you used it for awhile already? You might want to try replacing the burrs ($20) if they've been used for a few years.

Love your 'handle'!

I'm thinking that there is something in the burr in the unit. Empty the unit and remove the burr. Usually, this is done with a counterclockwise turn. Note how hard it may be to turn...you'll have to reverse this when you put it together. Now, clean out any coffee debris you find. Then, turn the unit over and tap it on a firm surface covered with newspaper. Reassemble and return to service.
