In simple terms, this spare part is the channel that directs the steam created by the boiler or thermoblock to the outside. Its main function is to allow milk emulsification, creating that dense cream typical of coffee shops, or to dispense boiling water for tea and infusions.\u003cbr\/\u003e\u003cbr\/\u003eSymptoms and Diagnostics (Q\u0026A)\u003cbr\/\u003eQUESTION: Why is the steam lance leaking water or steam?\u003cbr\/\u003eANSWER: Often the cause is wear of the internal o-ring seals or a micro-crack in the tube itself due to heat.\u003cbr\/\u003e\u003cbr\/\u003eQUESTION: The steam is coming out with low pressure, what is happening?\u003cbr\/\u003eANSWER: There may be a blockage caused by limescale or dry milk residues inside the duct.\u003cbr\/\u003e\u003cbr\/\u003eQUESTION: Why is my coffee machine no longer frothing milk?\u003cbr\/\u003eANSWER: If the tube is intact, the problem may be a partially clogged dispensing hole that prevents proper mixing of air and steam. Check for any build-up.\u003cbr\/\u003e\u003cbr\/\u003eQUESTION: Why is no steam coming from my coffee machine?\u003cbr\/\u003eANSWER: The problem could be caused by various factors. First, ensure that the steam lance is free from limescale or milk residue blockages, then check that it reaches the set temperature for steam and that the tap is completely free for dispensing from the steam outlet channel. Usually, a descaling or cleaning of residues resolves 90% of the issues. In our shop, you can find both the EcoDecalk descaler and the Eco MultiClean solution for cleaning milk residues.\u003cbr\/\u003e\u003cbr\/\u003eMaintenance Tips and Lifespan\u003cbr\/\u003eTo maximize the lifespan of your steam tube AS00007639 and avoid premature breakage, it is crucial to follow some simple rules. The number one enemy is milk build-up: this, when dried, creates hard plugs that are difficult to remove and promotes bacterial growth. We recommend purging the tube by dispensing steam for 2 seconds immediately after each use and wiping it with a damp cloth. Also, regularly perform descaling of the coffee machine, as limescale can accumulate internally, reducing the steam passage diameter and increasing internal pressure, potentially causing breakage or completely blocking the dispensing tap.\u003cbr\/\u003e\u003cbr\/\u003eInstallation Instructions\u003cbr\/\u003eInstalling 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 (cover, tank, drip tray, etc.), the outer cover, and the steam knob. Generally, the tube is secured with a screw fitting or a retaining clip. Unscrew or detach the old tube, being careful not to lose any seals, clean the housing seat, and insert the new spare part AS00007639, ensuring it is securely in place. Perform a steam dispensing test before reassembling the outer casings.\u003cbr\/\u003e\u003cbr\/\u003eNot exactly the item you are interested in?\u003cbr\/\u003eIn addition to the tube, we have a wide range of original Delonghi accessories and spare parts available in our catalog.
