Whirlpool Quiet Partner II flashing "normal"

I’ve read the other posts, and tried the reset codes. I haven’t seen any postings about a flashing "normal" light, though. This has been going on for a few months, but usually resets itself within a couple hours. Once it happened during a wash cycle. However, this time the light has been flashing for at least 5 days.
Not sure of actual age of machine, it was purchased by former owner of house. We moved in almost 3 years ago, and run it 3-4 times a week.
I would welcome any suggestions.
Thanks!
