Hello All,
Two days ago, my pool stopped runing, I went outside to inspect and it said there was a bridge comm error on my console (OnCommand). The Ecostar pump said check wiring between pump and display. There was nothing obviously wrong, but with the wet weather we were having, I went ahead and replaced all of the wiring. No luck, same error message. Running through the diagnostics menu I saw VOLTAGE TOO LOW, which may or may not be related, but obviously another issue. I feel the drive is the only thing left that could be screwed up, even though its only two years old (and a replacement of the pump that went out two years ago while still under warranty). Anybody had an issue similar to this?
Thank you for any help in advance
