Temperature sensor on thermoblock for Jura 300mm coffee machines

What the thermoblock temperature sensor does

The temperature sensor (NTC sensor) measures the water temperature in the thermoblock and sends this information to the coffee machine's control electronics. Based on this data, the machine regulates heating and keeps the water at the temperature needed for brewing coffee or producing steam.

Signs of wear or failure

• The coffee is too cold or, conversely, overheated and tastes burnt
• The coffee machine won't start or switches off during heating
• The display shows an error message related to temperature or heating
• Brewing coffee takes noticeably longer than usual

Why timely replacement pays off

An inaccurate or faulty sensor can cause the thermoblock to overheat or fail to reach the required temperature, which affects not only the taste of the coffee but can also lead to a bigger failure of the entire heating system. Timely replacement protects the other components of the coffee machine.

How to choose the right part

Sensors differ in the length of the connecting cable and the way they attach to the thermoblock, so before buying, check the exact compatibility in the product table according to your coffee machine model.
