Flashing power light and won’t brew

Worked great for several years. A few days ago after brewing a few cups I went to run a hot water flush and got nothing more than a flashing power light and it won’t do anything when pressing the brew button. I have tried the usual stuff (cleaning out the nozzle, unplugging and waiting a few minutes, etc.)

I figure I’m going to have to take it apart and look at it more but I’m hoping there’s simpler solutions to try first.
