Using the Carimali Bubble coffee machine is easy. First, make sure the machine is properly plugged into a 220V power outlet with a frequency of 50 - 60 Hz. Fill the 10.5 - litre water tank. You can adjust the pre - infusion using the electronic settings to get the best flavor from your coffee beans. When you want to steam milk, use the steam lever controls on the steam arm. For hot water, use the tap and select your desired temperature. There are 4 adjustable buttons per group for the volumetric option, which will automatically dose the coffee for you. When it comes to cleaning, let the machine do the work with its automatic cleaning cycles. Just follow the prompts on the digital display. Remember to descale the machine regularly to keep it in good working condition. Avoid using abrasive cleaners on the mat black and stainless - steel exterior. If you have any issues, check the user manual or contact customer support.
