What is a circulation tube
A circulation tube is a hose or a more rigid pipe that carries water or steam between the boiler and other coffee machine components, such as the flow meter, solenoid valve, or steam circuit. It ensures a closed circulation of water in the system and maintains proper pressure during both coffee brewing and milk frothing.
Typical signs of wear
Over time, the tube material can harden, crack, or become damaged at the connection point to the fitting. This shows up as water or steam leaks, dripping under the machine, a drop in pressure, or unstable water temperature, which also affects the quality of the coffee. A damaged tube may also cause hissing or bubbling of air in the circuit.
When it's time for a replacement
A leaking or cracked circulation tube increases the risk of water damage to nearby components and can cause the boiler or flow meter to fail. Timely replacement prevents bigger repairs and keeps the coffee machine running smoothly.
Choosing the right part
Since tubes differ in length, shape, and connection type depending on the specific machine, be sure to check the exact match in the compatibility table on the product page before purchasing.
