Advice on Jura Impressa and GIGA Coffee Machines.

Virtually all the Jura range have the same requirements in terms of maintenance and care. The major causes of problems with these machines are a build-up of lime scale and putting the wrong items in either the grinder, pre-ground coffee chute or the water tank.


The in-tank filters will deal with most of the lime scale and improve the taste of coffee as it removes contaminants. To use filters set the machine to 'Filter: Yes' and change the filter as soon as possible after the machine requests it.

Filters have a finite life span which will be marked on the packaging (usually two months) this period starts from when the filter is put in the tank and it must be changed by that date as the filter will start to disintegrate.

De-scaling (Decalcifying)

If you prefer to do periodic de-scales then you set the machine to 'Filter: No'. The machine will then periodically request a de-scale by displaying a message, you don't have to do this immediately as it takes up to 50 minutes to do.

The frequency of de-scales depends on the water hardness, this can be found on your water company's website and should be entered via the menu.

The de-scaling chemicals are quite strong so take appropriate care and follow your User Manual for the exact steps.

If your impressa machine has a plumbed in water supply connected directly to the tank you must turn off the mains water while de-scaling so that the correct amount of water is used for a descale.

Remember that de-scaling tablets are not the same as Coffee-cleaning tablets and they should be placed in the water tank with the correct amount of water.

Pre-Ground Chute

Never put anything like instant coffee, drinking chocolate etc. in the chute, only the correct amount of pre-ground coffee, avoid finely ground coffee as it will clog the chute. The only other item allowed in is a coffee cleaning tablet (not a de-scaling tablet) when doing a coffee clean.

When putting Pre-ground coffee down the chute remember that the chute tapers down to a small opening at the bottom, if you simply turn the scoop upside down and the coffee goes down the chute as a ball of coffee it can get stuck and fall out onto the back of the drip tray. The machine will give you a message like' Not enough Ground Coffee'. The cure is to pour the coffe in over the edge of the scoop so that it flows smoothly down the chute.

Grinder Care

The only thing that should go into the grinder are reasonable quality coffee beans that are not too cold. Beans that are straight out of the fridge or freezer will have condensation on them which will clog the grinder, oily beans also cause blockages due to their stickiness.

Avoid beans with any sort of coating on them.

Only adjust the grinder when it is actually grinding, so press a coffee button and turn the adjustment knob a small amount, then make another couple of drinks to test the effect.

Don't have the grinder set any finer than you need to get a good crema on the coffee.

Water Tank

Obviously water goes in here, also filters or de-scaling tablets, but never both at the same time.

Always fill the tank by removing it and taking it to the tap. If you pour water into the tank while it is on the machine some water will always splash out and get into the grinder or pre-ground chute.

The tank itself can be washed in soapy water when required.

If your machine cannot recognize that the tank is full and keeps telling you to fill the tank even when it is full, the problem can be that the floating magnet in the tank is stuck. The magnet is in a groove on the side of the tank facing the machine and is free to rise a short distance when the tank is filled which triggers a sensor. Washing the tank will normally cure this problem.

Some newer models do not have a magnet in the tank but use an electronic sensor, if this fails the only cure is to replace it.

Drip Tray

This can be washed as needed but take care to dry the area around the contacts (if fitted) on the back of the tray, particularly after de-scaling otherwise the machine will repeatedly tell you to empty the tray.

Milk Nozzles and Frothers

If these become blocked and have been cleaned with cappuccino cleaning fluid. Try soaking in a solution of biological washing detergent or failing that give them a soak in de-scaler.
Do not run hot water through the nozzles - or put them in the dishwasher, as they will stop working properly.

Jura are discontinuing the Litre bottles of Milk System Cleaner and switching to small pots of granules with a dispenser built into the cap,
refills are available to reduce the cost. View details on Jura's website Here .
