Check and make sure your ac cord is fully plugged into the back of the ref 6.
I also had this problem once fixed it by fully inserting the 20 amp pc cord.

ARC Ref 6 - Is it normal?
I got my ARC Ref 6 two weeks ago, and I use 3 pieces of Nordost Sort Kones BC to bring up my Ref 6 to test the sound. But when I switch on the power-on button, my Ref 6's display show "Low Line Detected" for almost 20 seconds then it back to normal (Display show "Mute"). Is it normal ? Will it show this everytime now? THX.
