Grinder will not stop

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 is a fuse connected to the grinder via the wire harness - it is a small rectangle fuse that is usually white in color and hard plastic materials - this usually mounts to the grinder and plugs into the terminal block - also could be the Power electronics - but check the fuse first

they usually keep grinding until the compartment with the grinded coffee gets full or until you turn off grinder. should turn off after compartment reaches full state.

Switch problem?

Unfortunately you must sent the machine to a service. Probably the transistor that drives grinder is damaged.

Empty the grinder and see if it will run with no coffee bean in it. Some times debris will get caught in the grinder because it got mixed with the beans from the factory. If it runs your good to go. If not then the mother connection are not solid and it will run off and on at will.

Check your power cord. Turn the grinder on, then pull and twist the power cord, especially by the boot coming out of the grinder. If there's a break in the line, it's possible for it to work in some positions but it will die if you change the orientation of the cord to the tool.

Hi,Ive just recieved an email saying that your having some problems with your machine. Its hard to keep up with all the error codes on the hundreds of machines on the market. Faulty grinder usually dont give an error code. The grinder will just not work if its faulty, which tells me theres a problem with grinder. If your showing an error 1, i'd be looking at the steam heating circuit. Faulty thermoblock, thermostat, solenoid, etc. Anyway, something has led you to replacing the grinder, so ill see if I can help. Some machines need to be told that it has been fixed, which is done through the programming. You know when you go in to the cleaning program, thats where it may have to be told. The grinder also has other electrical sensors which maybe at fault. On one of the wires that connect to the grinder is a little square thing that sits in a holder on the grinder. It maybe faulty.(not common fault that part). The machine will usually reset itself when you turn it off at the main toggel switch, and unplug it from the power point. When you turn the machine back on, it will do a self dianostic before it starts to heat. but as I said before, the grinder usually isn't part of the self dionostic on start up. If you turn it back on and error code comes back up, id be looking at thermoblocks or thermostats. If your still having troubles, give me more details on how the machines full operation is working. If the grinder is at fault, everything else should be working. Thanks Darryn

if this is a cap start motor and not a centrifugal start run motor then bad cap is good place to start

Try to use another brand and more dry coffee.
