Default Krell Evolution Two Problem????

I have a question regarding my Krell Evolution Two Preamplifier.

I noticed when I powered up my Evolution Power Two from standby today I received the following messages on the front of my right channel unit.

First it said:
DC offset found

Followed by:
Checking Outputs

Followed by the following two messages.
Then it goes to Cast Out 1 followed by Cast Out 2

Finally it goes to S1 which is the default output.

Then I can just hit the B1 output I am using to my matching Evolution One Mono Blocks.

Music plays as normal with no issues. Is there something I need to address? Should I be concerned at all. It would cost a lot to ship back to Krell from Canada and was hoping it was an easy fix from my end. Any insight or help would be greatly appreciated. The sound is fantastic as always just the few seconds longer to boot up.

I have attached photos in sequence. I rarely use the cast cables as I prefer my balanced interconnects more.

I am in no way qualified to offer advice on this error.That being said I would try cleaning all connections including the outlet and fuse connections and then try it.I would try a different outlet,circuit next if it still had problem. I would lastly disconnect all components and power up and see if it still remains.
Hope this helps.

Yup. Went back to the Krell OEM power cables on the amps and problem resolved. I guess the Krell Amps don’t like the heavy terminations on aftermarket plugs. Gravity tends to weaken the contacts???
