What is the Steam Tap Used For?
In manual espresso coffee machines, the steam outlet valve acts as a tap that diverts pressure from the boiler to the external spout (pannarello). By turning the knob, an internal shaft retracts or advances, allowing pressurized steam to escape. It is a mechanical component subject to wear as it must handle high temperatures and steam pressure.

Fault Symptoms - Q&A
QUESTION: No steam or hot water is coming from the coffee machine, why?
ANSWER: If the entire system heats correctly and turning the tap knob does not produce anything, the problem may be caused by limescale buildup or a faulty tap. Before replacing it, try performing a thorough cleaning using the original DeLonghi descaler, which is available in our shop.

QUESTION: How can I dispense hot water instead of steam?
ANSWER: There is usually an option to dispense steam; selecting it causes the coffee machine to heat more than necessary and turns the water into steam. If you keep the selector in the heating position for making coffee and turn the knob to dispense steam, you will see hot water ready for preparing tea and infusions.

Installation Instructions
Installing this spare part requires a fair amount of manual skill. Before starting, ensure that the machine is turned off, unplugged, and completely cool to avoid burns. Remove the movable parts (lid, tank, drip tray, etc.), the outer cover, and the steam knob. Once the top cap is removed, you will immediately see the tap connected to the boiler; simply remove the screws holding it in place and take it out.
