My Izzo was on for quite some time before I got to it. The low water sensor got stuck and the reservoir was empty. I pulled a shot and heard some whooshing sounds that I've never heard before. I looked at my reservoir, corrected the mistake and tried pulling more shots the next day. It looks like it pulled in some air, though.
The issue is that the machine is louder. I took it apart to find where it's louder from and it's coming from the rotary vane. It's like a vibrating buzzing sound. Could air getting in have done that? Is there anything I can do to fix it?
Thank you all in advance!
