Espresso Retro Hong Kong Limited is the offical distributor of Weber Workshops in Hong Kong Free local delivery will be included Patented Espresso Machine Cleaning Device Overview The Spring Clean™ allows a full 200mL of water to build up in a spring-loaded reservoir and releases that full amount back through the brewing pipe over the 3-way solenoid and into your drip tray. That means less time spent cleaning, and 20x the volume of water used to clean per cycle. A spring clean a day keeps the technician away. Fits standard 58mm machines that utilize a pump and backflush system for cleaning and maintenance. This includes E61 style group heads, most LaMarzocco (all except KB-90) and Decent compatible. Please Note: Does not fit Gaggia Classic Pro, Breville and machines with Bezzera BZ brew groups.x Materials This version is made from a tough food-grade and BPA/Phthalate/PFOA/PFOS-free polymer that allows you to see into the chamber to see directly how clean your machine is becoming. The silicone plunger tip is replaceable as needed. The springs are both made of stainless steel. The safety release pressure valve was developed in-house and is made entirely of stainless steel.
