Hayward Super Pump VS 700 Comm errors

This pump was installed in 2020 and hasn’t given me an issue until now when I went to open the pool today.

I was first greeted with this message:

“check system display comm failed - check wiring between display and drive”

I did some digging and called the dealer I got it from and they said to try a new display so I went and spent $400 on that (they said they’d take it back if it didn’t fix it). I get home and plug it in and the exact same error displays.

From here I pull the cover off where the wiring and other boards are and quickly see I had some definite corrosion and water intrusion.

I checked all my cables and I’m getting 12v out to the display as it should, but it seems like something else got fried….

I’m at a bit of a loss on where to begin or if there is anything I can do beyond this? I’m not seeing any replacement boards or pcb (I’m no electrical engineer here so excuse my terminology). So I was hoping to tap into the brains here to see if you have any further trouble shooting I could perform?

Secondary question is there anyway to jump the thing to just get it working at a single speed for now?

The display is not communicating with the drive electronics.

You can replace the display and drive but I think you will find buying a new pump is less expensive.

There is nothing repairable in the drive and no way to run the pump without everything working.
