Steam Pump +Thermostat

What the part does

This is a combined pump and thermostat assembly that ensures the flow of water or steam in the coffee machine while also monitoring or regulating the temperature in the relevant branch of the circuit. The pump generates the pressure needed to push water through the heater and brewing unit, while the thermostat monitors temperature and protects the system from overheating or from operating outside the correct temperature range.

When the part stops doing its job

A worn or damaged assembly shows itself through weak or irregular water or steam flow, a noisier running pump, fluctuations in coffee temperature, or a complete loss of function where the machine stops drawing water or producing steam. A faulty thermostat can cause the water to fail to reach the correct temperature, or conversely lead to overheating and a safety shutdown of the appliance.

Why timely replacement pays off

Delaying replacement can lead to uneven coffee extraction, insufficient steam for milk frothing, or a total breakdown of the machine. Early replacement prevents further strain on the heating system and protects other components from damage caused by incorrect temperature.

How to choose

• Check compatibility in the product's table according to your coffee machine model.
