If your Breville Bambino Plus is not building pressure during extraction, it can result in weak or watery espresso. This common issue often stems from blockages, scale buildup, or worn-out parts. Fortunately, with some careful steps, you can diagnose and fix the problem yourself, saving time and money.
Before starting, ensure you have basic cleaning supplies, replacement filters if needed, and a clean workspace. Always follow safety procedures when handling hot water and electrical components.
