2022 TX Hot Springs controller flashing off and on

[vdriveride]

One minute everything was working and now the control panel flashes on and off. I need help have tried everything I can see and all appears okay. With the controller flashing off and on, nothing works.

Do the lights on the circuit board also go on/off?
