5 month old Breville Express - Is it dying? No noise when turning on and takes 20 seconds before pump starts when making a shot.

[Cayaco]

It just started this week. I went to turn it on like I always do and instead of the normal loud pump noise getting things ready there is just a very faint humming, if you werent listening for it you would think it was just silence. Then when I push the shot button to start making a drink the machine just sits there for 20 seconds doing nothing that I can really here before the pump then suddenly kicks on and water starts flowing. It used to start pumping water and getting the pressure up right away when pushing it.

Any ideas? It's not even a year old. Bought it in November. I ran a descaling clean out cycle around Easter.
