When to replace hydraulics parts
Keeping the hydraulics in good shape matters because the hydraulic system moves water through the machine, and its pumps, tubing and fittings are frequent failure points. This page covers pumps, solenoid valves, tubing, fittings, check valves and o-rings. Watch for no water flow, a noisy or failing pump, internal leaks, or pressure that won't hold; when you spot them, swapping the part is often all it takes to get back to great espresso.

To avoid ordering the wrong part, check your model against the fitment notes on each product, or reach out to us and we'll confirm compatibility for your exact machine.
