Coffee beans flashing

Hi everyone!
My Jura ena Micro has beans blinking alternately. When I then press on the bean it tries to suck in water with quite a noise, but nothing happens. No water
coming out. Can someone help
me out?
Thank you in advance! LG Marion

Is water coming out of the hot water nozzle? Has there been any cleaning with tablets recently? Is the chute free? Is a filter being used (first get out with the shit and try without)?

Hello and thank you! There's
no water coming out of the nozzle. One hears that the machine tries to "pump" water but nothing comes out. It was cleaned some time
ago.
I've already removed
the filter.
The shaft's clear, too.

Hi,
I have an ENA Micro 9 and a similar problem. During rinsing, the machine found it difficult to pass the water through. Occasionally the display showed that the system had to be filled - which only partly worked. I then disassembled the machine and checked all the hoses (i.e. just those where I got it) ...from the water tank via flowmeter to the pump and from the outlet valve back to the brewing unit. Right in between so ceramic valve and further I did not test. (I would have had to dismantle the whole machine)......no matter. ....I then carried out another decalcification although I had always decalcified regularly. But since we have a very high lime content here - I did not take the recommended dose but used the ratio 3:1.
Only then did the machine flush clean again. So there must have been some deposit in the device.
Good luck

Hi,
I had the same problem, and agree that it is most likely a blocked pipe. Here’s my no-screwdriver fix:
I suspected limescale blockage, so half filled the reservoir with water plus 3 descaler tablets. Then I pressed the bean button to suck water into the system and repeated at intervals over 24 hours.
My thought process was that if you leave the descaler long enough to sit in the pipes, the head of the water will dissolve whatever’s there.
For good measure, I then ran a further couple of descaler and cleansing cycles through the system.
Have had success with two constipated Jura machines
