We've recently encountered the message "empty drawer" on a couple of Z5 machines. Seems fairly straight forward until you find that emptying the waste drawer has no impact whatsoever.
What's going on?
Well through a little trial and error we've discovered that the messages are the result of water getting on the "contacts" at the back of the waste drawer.
We're not quite sure why so much moisture should be getting into this area, however it could be the result of the user washing the drawer and not drying it throughly. Although on further conversation with Jura it could also be the result of the machine not sitting on an even surface.
Solution - Ensure machine is disconnected from any electrical connection, remove drawer, and dry all contacts. Apparently a hairdryer is very effective. The main thing is to ensure that all contacts are dry.
We're not done quite yet, the drawer now needs to be left out for a few hours, preferably over-night, and the machine kept switched off.
The theory is that the following morning the message will have cleared and you will have a normally functioning machine.
Lesson of the story, when removing the waste drawer and cleaning, ensure that all parts are totally dry before replacing said drawer.

With the Jura ENA 5 machine what are the thoughts reference using the Claris filter or NOT with the Jersey mains water or go along with the descaling tablets?.

As discussed using the Claris filter as supplied by Jura and used in accordance with their instructions will mean that should you have any issues with the machine the warranty will still be valid. There is a danger that if you don't use the filter and some particulate gets into the core of the machine due to the lack of a filter then Jura may not honour the warranty.
I would add that the filter does not stop scale getting into the boiler, it is there to remove other contaminates. You will still need to descale the coffee machine when signalled by the machine. In this respect you should follow the manufacturers instructions as to the hardness of your water as this will determine how often the machine should be descaled.
