Customer: "The machine is great, والله (by God), and working perfectly, but it needs a simple pressure adjustment!" Me after opening the heater: "So that's why the coffee was coming out with 'new spices and flavorings'... a classic mix of limescale and sediment without us even knowing! 🧂🤦‍" This doesn't need a pressure adjustment, it needed a lifebuoy! 😅 Routine maintenance is not a luxury, it's what preserves the taste of the coffee and the life of the machine..
