I have run foul of this same issue and have to agree with double_shot and motoman that the generic E61 shower screen being supplied by a number of vendors is of very poor quality.
The original shower screen supplied with my Duetto is of excellent quality and looks identical to the original screen in double_shot's photos in his first post. The generic replacement is, unfortunately, identical to the replacement in his photos.
The generic screen is made from thin, soft steel and is spot welded. Â It also lacks the ridge formed in the original part that stiffens the side walls and allows for removal of the screen with spoon handles without damage to the screen. Â
I have only used the generic shower screen occasionally and for short periods, whilst the original screen is cleaned, as I find the original screen produces better espresso. My generic screen is now unusable due to deformation of the thin side wall, causing leaks past the gasket, and spot welds failing, causing channelling. Â The original screen shows no problems at all even though it has been in use for much longer and has been removed and replaced many more times. Â
I have been trying to source a replacement good quality screen as my original is now four years old. I see they are available from
espressoparts.com but they do not seem to ship outside of the USA and Canada. Has anyone found a source for the better quality shower screens in Europe?
