Severin Heating Element / Thermoblock Failure

Water does not heat; coffee is brewed with lukewarm or cold water.

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

Open-circuit heating element, Faulty thermostat stuck open, Defective NTC sensor misreading temperature, Burned relay contacts on PCB

Safety first: Unplug the coffee maker and let it cool.

Confirm symptom: Start a brew cycle with water only and check if any steam or heat is produced at the outlet after a minute.
Descale: Heavy scale can insulate the heater. Run a full descaling cycle as per Severin instructions.
Listen for boiling sounds: If you hear boiling but water is still cold at the outlet, there may be a blockage rather than a dead heater.
If no heat at all: The heater, thermostat, or control relay is likely defective and must be tested and replaced.
