Coffee is lukewarm or not hot enough even after preheating.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

Possible Causes

Partially failed heating element, Faulty thermostat opening too early, Temperature sensor misreading low, Excessive scale insulating the boiler

Safety first: Unplug and cool the machine before internal checks.

User actions:

Preheat properly: Allow the machine to warm up fully and run a blank shot to heat the group head and cup.
Descale: Run a descaling cycle to improve heat transfer.

Advanced:

Test heater: Measure resistance of the heating element and compare with specifications. A significantly higher resistance may indicate partial failure.
