My Jura Capresso # 8 is stuck in Fill Water, the floater is Ok, the water is moving, what can I do.

My guess would be that your water tank float is trapped.
The remidy would be to descale the watertank itself.
If you use the Calris filter cartridge. remove it before descaling with a mild commercially available descaler. Don't forget to rinse thorrowly afterwards and reinsert the filter. Always use cold water to fill the watertank.
Hope this helps

Fill the water tank with vinegar to dissolve the chalk and make the swimmer swim again. It is stuck! You can help and poke the swimmer with a knife from the side.

make sure the water tank is full! there is a small float in the tank that moves up and down near the bottom, make sure this is up and not stuck down.

small black rectangular float is stuck in the water tanks . take off tank and empty. then shake you will see it on the side wall (machine side) if it does not rise when water is filled the machine still thinks its empty

check small float in tank is not stuck in the down position

small float in tank stuck in down position. remove tank and clean with hot water. rinse the give a good shake you will hear float rattle in tank

Hello, make sure the magnet in the water tank moves freely, sometimes it gets stuck with deposits, its a small black rectangle near the base. if its not free, you need to put some descaling solution it the tank to clear it.

First, I'm not JURA technician. But I have worked on similar table top "Super Automatics" You should call your vendor or the MFR for service. Especially if it's still under warranty. There are no customer serviceable parts in this machine.
*** the following is for information only ***
- Water not getting to machine or not sensing that the water tank is already filled.
* There usually some type of float near to middle of the water tank. It's usually white or colored plastic. This 'float' needs to move freely up-down to 'sense' the filled tank. clean the tank and shake it -note the movement of this float. It will need further cleaning if it's stuck (or you will have to replace tank if it's crudded up).
* Re-install tank and fill with filtered water. Turn machine off, count to 15 then turn on again. This usually turns on pump to add water to inner tank. If this does not happen then there is a CPU problem. If it does hums for 5-10 seconds then goes off but no heating then the pump may have an air bubble in line. Try the turn off and on method several times (up to 5) to get the water flowing. If it's still not working then there is a clog in the pump and will need service and/or replacement.
* Since this is a table top machine in which you fill the water tank. Try to use filtered (bottled ok) water. Do Not use Distilled or 100% pure water as this type of water will eat out the metals from your machine! Some places use a water softener as it tends to be better for the machine long term (years).
* Still got problems? Check with vendor or MFR for service or replacement. Most machines of this type do not have serviceable parts or adjustments.

PS: I've noted this tank also uses a water filter (which is probably dry after sitting around for a year as you mentioned.) you will probably have to flush out the air in the filter prior to this unit's pump to work properly. I found a youtube vid that may help:

System fill is usually when the machine auto solenoid fill valve is putting water into the boiler. If it is making noise then the solenoid is clogged or there is no water getting to the solenoid.
