Problems with Jura Impressa C5 with Zero-Energy Switch
Hello,
we have a Jura C5 to repair. The machine has pressed the coffee into the marc container every few covers. Finding and fixing the error was not difficult. The white cap on the pin of the drainage valve was broken, so the pin often got stuck in the drainage valve.
As we should also do a cleaning of the machine we disassembled the machine like other Jura E, C etc.. When we were finished and everything was wired again, we tried the machine out.
Now it does not work anymore. If you press the Zero-Energy Switch, it indicates that you have to empty the pan, pull the pan out and push it back in again, the machine goes out, it doesn't let the brewing group go back and forth after switching it on either.
We've already swapped the cables, but nothing has changed.
If you push the switch in and hold it down, it shows the machine to open the tap. If you do that, "cold" water will leak, too. If you close the tap and release the button, the machine goes off again.
We don't know any more, the best would be if we had a power plan or at least a photo of another machine.
I think it's because of this new Zero-Energy Switch.
Because Jura has the following on the side:
"This patented innovation from JURA stops a running coffee brewing process when the machine is switched off, ejects the coffee grounds and returns the brewing unit to its starting position. Finally the switch disconnects the device from the power supply."
On other machines we never had the problem.
It would be great if someone had an idea.
More greetings
Rafael
