- Useful Tips: If your machine shows โEPโ or a low-water warning but the tank is full, donโt worry โ itโs usually not a fault. This can happen when the grind is too fine or the coffee is tamped too hard, blocking the flow. Simply use a slightly coarser grind and try again. Coarse grind, low dose, or weak tamping can also cause low pressure and thin crema. Always use freshly ground beans (18โ19 g for a double shot). Once you find the right grind, extraction becomes perfect. If you need help, please contact us anytime.
