Hi, I replaced a Hayward pump with a variable speed Pureline Pump in 2019 and it's been working pretty well except last summer, the digital display stopped working. My previous schedule had been saved so I was able to get the pool opened by using the override buttons to keep it running, but I'd like to get the display working again.

It's a Century /AO Smith V-Green 270 user interface controller. I removed the display from the pump and expected to see some corrosion from water seeping into the control board, but it's pristine.

Any other suggestions on what could be wrong? Or anything else I should try to get the display up and working. i already disconnected the display cable and cleaned it but again, it looked perfectly fine.

This is the controller info page, but it came with my Pureline PL2626 pump

Thanks for any ideas you might have.

I went ahead and reattached the user interface and the display works now. If I'm being honest, I don't think I did anything to fix it. I did remove the wires from the connector instead of just pulling the connector out and cleaned the lcd connector with some rubbing alcohol, but aside from that...Nothing.
I'll leave this post up in case anyone else needs it. Here's a link to a YouTube video I referenced to remove the circuit board and check for corrosion
