Grundfos cu 301 voltage light

Grundfos 301 voltage led is red. We had a pretty good thunderstorm earlier. Not really sure if there is anything I can do?

That pump will run without the CU301 box. Hook it up direct to the breaker or use a regular pressure switch to see if the pump is still good. If the pump still works you can add a CSV1A that will give you the same constant pressure and not need the CU301 controller.
