These common issues are easily related to a lack of maintenance that can be easily avoided. Below you can find some useful tips as well as a cleaning products list compatible with any De’Longhi coffee machine:

  • Use fresh water every day;

  • Choose good quality coffee beans! Please avoid any coffee beans that are too oily, caramelised or coated as these can stick to the grinder resulting in permanent damage;

  • Store your coffee beans correctly: In dry and dark places;

  • Regularly make your favourite drinks with your machine so all internal circuits remain clean and away from limescale buildups;

  • Set the coffee grinder only when the machine is actively grinding the beans, otherwise, you risk jamming the grinder;

  • Use the DeLonghi descaler and never vinegar! Depending on the hardness of the water you use, your coffee machine needs to be descaled less or more frequently. Only a good descaling solution will help your machine to be properly maintained that is why we strongly suggest using our De’Longhi EcoDecalc to make sure you obtain the best result in cup. Vinegar, on the other hand, is prone to leave a strong smell and an acid taste to your coffee;

  • Use our WaterFilter or SoftBalls to improve the water quality and consequently the taste of your coffee. Another key factor is that they help reduce limescale and frequency of the descaling procedure that remains necessary when the coffee machine asks for it;

  • Daily rinses are necessary! Most coffee machines make them automatically when they are switched ON/OFF. If your machine does not have the AutoRinse function remember to rinse it every time you use your coffee machine to avoid the coffee residual buildups on your appliance.

  • Remember to clean every removable accessory connected to the main appliance such as Milk containers, steam wand, porta filter, hot water pipe, drip tray and ground container. To keep these accessories well-cleaned and in optimal condition please make regular cleanings using the Eco MultiClean, a detergent designed to remove milk residue and effectively clean external and removable parts of your coffee maker.

  • Clean the Brewing unit every week! Before extracting the brewing unit, be sure to turn your machine Off from the On/Off button and wait for the complete shutdown procedure to be completed. Only after, you can extract the Brewing unit and clean it with WATER ONLY. We suggest immersing the Unit underwater for some minutes and then rinsing it under tap water. Dry the Brewing Unit and insert it back into the machine.
