Connection piece for DeLonghi Lattissima steam heater

What this connector does

The connection piece for the DeLonghi Lattissima steam heater links the steam heater to the rest of the machine's internal circuit, allowing steam to travel securely from the heating element to where it is needed for milk frothing and cleaning cycles. It is a small but essential fitting that keeps the steam pathway sealed and stable during operation.

Signs it needs replacing

Over time, this connecting piece can wear, crack, or lose its tight seal due to repeated heat cycles and pressure. This often results in steam leaks, reduced frothing performance, hissing sounds, or visible moisture around the heater assembly. Replacing a worn connection piece promptly helps restore proper steam flow and prevents further strain on the heater.
