Melitta Low Brew Temperature

Coffee temperature is too low even after preheating cups.

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

Thermoblock not reaching target temperature, Incorrect temperature setting, Heavy limescale on heater, Faulty temperature sensor calibration

Safety first: Unplug before internal work.

User steps:

Increase temperature: In the settings menu, set coffee temperature to the highest level.
Preheat: Run a rinse cycle into the cup before brewing to warm the cup and internal paths.
Descale: Perform a full descaling cycle to improve heat transfer.

If temperature remains low, the thermoblock or NTC sensor may be faulty and require replacement.
