This product is a full set of 20 items, including the disassembly and cleaning of the generator for ECAM23120 and ECAM23210, and the following parts: a 14.5cm silicone tube, and O-rings (H) 1, (D) 2, (C) 1, (B) 6, (A) 6, (V) 1, (W) 1, (X) 1, and (Y) 1. The black O-rings are nitrile rubber. Now, Each part of the generator will be explained with the following designations: The generator consists of a boiler and an extraction device. The extraction device is divided into an inner cylinder and an outer cylinder. Inside the inner cylinder are an injection rod and an exhaust rod that runs along the outer cylinder. The protruding rod of the inner cylinder is the injection rod, which uses 3 O-rings (B 3). The exhaust rod, which is screwed to the outer cylinder, uses O-rings (D 2) and (B 1). The connector from the outer cylinder to the housing side uses (C 1) and (A 1). The connector from the boiler uses 4 O-rings: (V 1), (W 1), and (X 1) inside, and (Y 1) is placed on the outside. An O-ring (A 1) is used in the boot of the connector, which is connected to the steam nozzle. An O-ring (A 1) is used at the entrance of the steam nozzle. An O-ring (A 1) is used on the coffee injection rod from the extraction unit. The boiler-side connector has double O-rings (B 2) and (A 1) in the boot. An O-ring (A 1) is used in the boot of the outlet from the generator, and a silicone tube (transparent, 14.5 cm long) is connected. Finally, the extraction ring (H 1). Finally, If you are familiar with DIY, you should be able to maintain the Magnifica S model sufficiently. It's a high hurdle for beginners, but if you can master the trick of inserting the horseshoe-shaped clips that hold the tubes, then you'll need to make a substitute for the 8th and 9th slider stoppers, which are easily lost. It is very important not to lose them.
