Frequently Asked Questions

Why does part MC752-7 fit Lelit, Quickmill, and ECM machines?

Lelit, Quickmill, and ECM share a common boiler design and component ecosystem across several of their home espresso machine models. Part MC752-7 is a shared OEM specification used across these brands for the boiler seal on machines in this range.

How do I know if my boiler seal needs replacing?

Common signs include water pooling inside the machine case, steam smell without the steam valve being open, or visible wetness around the boiler body. The seal should also be replaced as a precaution any time the boiler is removed for service — reusing a compressed or aged seal risks future leaks.

Should I replace the boiler seal during a full service?

Yes — it is best practice to replace the boiler seal whenever the boiler is removed. At $12, the seal is low-cost insurance against a future water leak after reassembly.
