Hi all To set the scene I am a home enthusiast with scope for user error! I recently bought (this week) the aforementioned machine, But I wanted to check whether my Simonelli is working OK. When I extract a coffee it makes a high pitched sound rather than a low grumble which I would expect. I am wondering whether it's OPV related (never had one installed before). I am wondering whether it's the coffee itself maybe being too fine and the machine struggling to push the water through? If I remove the coffee basket and just run water through, it starts with that pitch got a second then is what I would expect is a normal sound. This is probably a very confusing post! Thanks
