Possible Causes

Safety first: Unplug before descaling if you need to move the machine.

Preheat cups: Rinse cups with hot water from the machine or use the cup warmer (if equipped) before brewing.
Disable eco mode: Check settings and turn off or adjust energy-saving modes that lower brew temperature.
Descale: Perform a full descaling cycle to remove scale from the boiler/thermoblock and temperature sensor surfaces.
If still lukewarm: The NTC sensor or heater control may be faulty. A technician can test and replace the sensor or thermoblock.
