The original water handle in Saeco coffee machines is always a pain in the neck. It's too fragile and won't last long unfortunately. As mine was broken, I've created the replacement spare part that fits the tank and is much more durable.
I didn't verify it but I’m pretty sure it will fit according to the spare parts catalogues.
