Senseo Heater Not Energizing

Power light is on but machine will not start heating; water stays cold and no steam.

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

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Failed heating element in boiler, open thermal fuse, faulty heater relay on control PCB, broken heater wiring

Safety first: Unplug the machine and allow it to cool. Heater circuits carry dangerous voltage.

Confirm symptom: After turning on, wait several minutes. If the boiler area does not warm at all, the heater is likely not powered.
Descale (if intermittent): If heating is intermittent, run a descaling cycle to improve heat transfer.
Internal diagnosis: A technician should measure heater resistance and check the thermal fuse and relay on the PCB.
Do not bypass safety devices: Never short the thermal fuse or thermostat to force heating.
