Thank you for posting! I have a question. The built-in grinder can't grind fine enough to get any pressure. At the lowest grind setting, pressure is still low. If I grind 18 grams of beans, the coffee doesn't fit in the basket. I am using 16 grams instead. Next, the machine keeps pumping water for 30 to 50 seconds. When I stopped the extraction after 25 seconds, the coffee tasted strong and bitter. How do I get less water while maintaining the same fine grind and pressure? How can I set the extraction time shorter? Do I need a dual-walled basket or not?
