    De-scaling

    To start the de-scaling programme, switch off the machine.

    The de-scaling programme for your NESPRESSO N90 can be started at any time with or without display prompt:

    • With display prompt:

    If SCALED / READY  lights up in the display, switch your NESPRESSO N90 off and hold the Programming key down until TRAY / EMPTY is displayed.

    • Without display prompt:

    If READY lights up in the display, switch your NESPRESSO N90 off and hold the Programming key down until TRAY / EMPTY is displayed.

    If MACHINE / DECALC. is displayed for an extended period, the de-scaling programme was started with too much liquid or the water was replenished before the tank was empty.

    • Tip: start the de-scaling programme again with 0.5l water. During the de-scaling programme, the water tank is completely emptied. Please do not refill with water until you are prompted to do so in the display.

    If SCALED / READY lights up even though the CLARIS filter cartridge has been inserted, the filter was not programmed.

    • Tip: remove the filter and run the de-scaling programme. Then insert new filter and program the machine correctly.
    • Note: please remove the CLARIS filter cartridge from the water tank during the de-scaling programme. If nevertheless the filter is not removed, the coffee will taste unpleasant as the filter will be soaked with de-scaling solution.

    CLARIS filter change

    The filter change programme for your NESPRESSO N90 can be started at any time in either of two ways:

    • With display prompt:

    If FILTER / READY lights up in the display, hold the Programming key down until FILTER appears. Then briefly press the Programming key until REPLACE is displayed. Now insert a new filter and very briefly press the Programming key again until VALVE / OPEN appears. As soon as you pull the valve upwards, the machine will begin to rinse the filter.

    • Without display prompt:

    If READY lights up in the display, hold the Programming key down until FILTER appears. Then very briefly press the Programming key until REPLACE is displayed. Now insert a new filter and very briefly press the Programming key again until VALVE / OPEN appears. As soon as you pull the valve upwards, the machine will begin to rinse the filter.

    • Note: the water may be slightly discoloured, but this is not hazardous to health.
    • Tip: if the volume of drinks dispensed is low, the CLARIS filter cartridge should be replaced every two months, although the prompt to do so does not appear in the display.

    Coffee taste and temperature

    Coffee taste:

    Are you unhappy with the taste of the coffee? If the coffee tastes unpleasant, this could be due to any of the following reasons:

    • The de-scaling programme was run with CLARIS filter cartridge inserted. In that case, take out the filter, insert a new one and program the machine accordingly.

    Coffee temperature:

    Is your coffee not hot enough? The following are some reasons why the coffee might not be hot enough:

    • If you are not using a CLARIS filter cartridge, your machine may be furred. Check the water hardness, program this correctly and de-scale the machine.
    • Tip: heat up your cup!

    Milk foam

    The NESPRESSO N90 is supplied with the hot water nozzle as standard. However, thanks to the Connector System©, you can connect the Cappuccino Frother (fine foam frother), which will allow you to froth milk.

    If the milk is not foamed with the Cappuccino Frother (fine foam frother), the frother is blocked. Remove the frother and clean it thoroughly.

    • Please note that the frother must always be cleaned thoroughly after a drink has been dispensed (with froth).
    • Tip: for cleaning purposes use the special JURA Auto Cappuccino Cleaner.
    • Note: the fat content of the milk has no effect on the froth. Even skimmed milk can be used.
    • Tip: if you are not using a CLARIS filter cartrdige, the de-scaling programme can be run, as lime deposits can impede the drawing off of steam.
