Jura fault 1

I have 3 different coffee machines and all 3 are descaling like you said using only the froter so that is normal .... Unless you misstyped the question

Open the whole machine and you'll find the spout. Tighten up the nut there, the washer is like a tap thats dripping

most likely a main cpu board failure, this could be very expensive repair

hi this video will help you, Good Luck.

The message 'FAULT 5' on the Jura Impressa F7, appears when there is a problem with the heating sensor. Normally it needs service or replacement. You can try to unplug it from the power supply for an hour and then open it again. See if it works.

First you have to turn the machine off and then press and hold rinse buttom until you read empty tray and then follow the rest of the instructions. Good luck

You should decalcify, when you steam the milk some what gets through to the steam and the build up of these minerals causes the issue
