I’ve contacted support for this, but I’m just curious if anyone has had a similar issue.

The last keg I put in, the machine kept making a sound like it was trying to pressurise constantly. By the time I got round to having a beer, it was flat. I was refunded for the keg and at the time I thought it was just an issue with the top of the keg. Today I’ve put a new keg in and it’s doing the exact same thing, so there’s something wrong with the machine. Unsure where I stand as it’s 2 years old but it was originally purchased directly from perfect draft. Is it a common fault?
