If you have been using your La Specialista Arte for some time and never did a descaling on it, it might be limescale. Limescale could lead to malfunction that could impact the optimal temperature in cup as well. Some tips to obtain a hotter beverage are: perform a rinse cycle, and warm the cups by rinsing them with hot water using the hot water dispenser. Use De’Longhi Espresso glasses, made with a high quality \'double-wall\' glass. Their thermal capability keeps your beverage hot.
