Your machine requires routine maintenance for optimal performance. If you have not already done so, descale your machine according to the instruction manual to eliminate the limescale which could impact the optimal temperature.  Additionally you can perform a rinse cycle or warm the cup by rinsing with hot water using the hot water dispenser. We also recommend our De’Longhi Espresso glasses, made with a high quality "double-wall" glass with thermal capability to keep your beverage hot.
