Introduction:When the three indicator lights on your De'Longhi fully automatic coffee machine flash simultaneously, many users may feel at a loss. This article provides a detailed explanation of the common causes behind the three-light anomaly, including grinder blockage, misuse of the pre-ground function, coffee bean depletion, and descaling reminders, along with corresponding troubleshooting steps. Additionally, it introduces the Dolce Gusto capsule coffee machine, developed in collaboration with De'Longhi through Nestlé’s technology, and explains how its 15-bar high-pressure system and professional-grade coffee capsules can bring home brewing closer to café-quality flavor.
When using a De'Longhi (De'Longhi) fully automatic coffee machine, if you notice all three indicator lights lit up and continuously flashing, it usually means the machine is signaling some conditions that require immediate attention. To quickly identify the cause and resolve the issue effectively, it's essential to understand what each specific light combination indicates.
One common situation is when the grinder operates with an unusually loud noise, which is typically caused by a small amount of coffee beans getting stuck or clogged inside the grinder. In this case, it’s recommended to first try cleaning the grinder. If the problem persists, it’s best to directly contact the retailer or De'Longhi’s official after-sales service to avoid further damage to the machine's internal components.
Another possible trigger for the three-light flash is when the user selects the pre-ground coffee function without placing any pre-ground coffee powder in the machine. This incorrect setting will prevent the machine from operating normally. The correct approach is to add an appropriate amount of pre-ground coffee into the coffee powder chute, or switch the function back to using whole coffee beans.
If the coffee bean container is completely empty, the machine will also use the three-light flash to remind the user to refill promptly. Moreover, this light pattern may also indicate a descaling alert, meaning that scale has built up inside the water circuit and needs to be cleaned. It is recommended to follow the descaling procedure outlined in the De'Longhi original user manual, using the designated descaling agent, and completing the process step by step to maintain the coffee machine's optimal extraction performance and longevity.
Additionally, if the three lights remain steadily lit, it usually signifies that the coffee grounds container is full or has not been properly repositioned after cleaning. In this case, you should immediately empty the drip tray and the coffee grounds container. It’s advisable to check and empty the grounds container while removing the drip tray, even if only a very small amount of residue remains. Ignoring this step may lead to rapid accumulation of residues, which can affect the normal operation of the machine and may even cause blockages.
Aside from troubleshooting the De'Longhi coffee machine, there are also many convenient and fast capsule coffee machine options on the market. Among them, the Dolce Gusto series under Nestlé is a product developed in technical collaboration with De'Longhi. This series was launched in markets such as Switzerland, Germany, and the UK starting in 2006, later expanded to Spain, and officially entered mainland China in 2013. Its sales network now covers more than 70 countries worldwide.
The Dolce Gusto capsule coffee machine utilizes advanced technology originating from Switzerland and is equipped with a high-pressure extraction system that can reach up to15barbars, a pressure level that is close to that of high-end machines used in professional cafés, enabling it to fully extract the essence and aroma from the coffee grounds.
The coffee capsules used in this series are made from100% carefully selected ground coffee, with high-quality Arabica (Arabica) small-bean variety coffee beans as the main ingredient. From sealing to brewing, the original flavor of the coffee is preserved. Users can enjoy a café-level professional coffee experience at home in just a few minutes.
Dolce Gusto not only offers easy-to-use home brewing solutions, but its innovative capsule system and machine design have also become one of the most representative product lines within the Nestlé coffee brand, providing consumers who value convenience and quality with stylish and functional choices.
