Tefal Insufficient Brewing Temperature

Coffee is lukewarm or not hot enough when dispensed.

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

Faulty temperature sensor, Thermostat opening too early, Heavy scale on thermoblock, Preheating not completed

Safety first: Unplug before internal checks.

Steps:

Preheat properly: Allow the machine to complete its preheat cycle before brewing. On some models, run a blank shot (hot water only) to warm internal parts and the cup.
Descale: Scale acts as insulation and reduces heat transfer. Run a full descaling cycle.
Warm the cup: Rinse the cup with hot water before brewing to reduce heat loss.
Internal check (advanced): If temperature remains low, the thermistor or thermostat on the boiler may be faulty and require replacement.
