Jura Common Problems and FAQ
Although Jura coffee machines are indisputably well made and very well designed both technically and aesthetically, there are always going to be some problems somewhere in even the most well thought out design.
So here, we intend to create a list of common problems that can affect either a single make of Jura coffee machine or an issue common across the brand and hopefully some helpful guidance to resolve or identify the problem.
No milk flow
Without doubt, the most frequent problem encountered has to be with milk! And its no surprise really, when you consider you are dealing with a fresh dairy product that needs to be kept cool to avoid going bad.
If you have a Jura milk frother attachment on your machine (NOT a stand alone Jura automatic milk frother as these are a separate entity) you will need to keep it clear of milk residue in order for it to continue to produce the beautiful fine foam necessary for cappuccino and macchiato. We will add in some pictures below of the types of frother and how/where they require cleaning, but suffice to say that any thickening of milk in the passages will stop the flow of milk and you will have a frother that simply blasts steam out!
If you have a frother that does not produce steam? that is a separate issue to be dealt with later - for the moment we will assume your Jura is producing steam and that either the milk is not flowing OR the milk is flowing but is not warm or not frothy!
The video below is helpful for most basic frothers.
If your milk is not flowing, you will need to disassemble the frother into its components (see below), check and clean each item thoroughly and blow through where possible, once happy all is clear carefully re-assemble and test again.
Sometimes you may get milk "spluttering" through instead of a nice flow, and if all areas are free of blockages, this may be down to an air leak. The Z5/Z7/Z9 frother assembly in particular can split along the body mouldings with age and allow air in which reduces the suction of milk and causes severe spluttering of milk.
If your milk is flowing, but no longer frothy, it will be down to the air intake nozzle being either dirty, blocked or just old and needing replacement or the passageway in the dial having an obstruction. The Air intake nozzle is located in different positions depending on your machine, but will always be part of the frother assembly - its job is to allow a tiny amount of air in with the milk, which creates the froth - the air nozzle has a rubber pointed piece which should open up when squeezed.

If you are lucky enough to own a Jura Z6 there is a special additional cleaning guide from Jura which we have loaded here - Link
The frothers with removable dials need to be checked inside to keep the passageways free of milk residue
Below are pictures of two types of milk frother showing the spindle which pulls out of the majority of manual frothers (where you have a dial or switch on the front to turn to select the froth or flat milk) take the dial between thumb and forefinger and withdraw from the main body and check the passageways and clean out as required - some will also have a tiny hole in the passageway
Descale option not showing
On the majority of early Jura machines, the maintenance system was set up to either filter OR descale, this means that if you want to carry out a descale and your machine has been using filters, the option to descale is not available in the menu. To reactivate the option to descale, first the machine must have the filter option/setting changed to "Filter NO" once this has been changed, the descale option should appear in the maintenance menu in place of the filter change option - If not the machine may first require a power down and power back on to restore the descale option.
