Hey guys opening my pool for the season and everything was fine until I turned on pump today. It was working yesterday. I hear the relay click and pump doesn’t turn on. I changed the relay because I had a spare, same issue. I then see a “communication error” displayed on screen but that’s all it says. If I turn off breaker sometimes that error will show other it will not. Any ideas?? Possible board I’m thinking?
 
Do you have a multimeter and know how to check voltages?

Check the pump circuit breaker.

Check voltage at screws 1 & 3 of the pump relay to see if you have power into the relay.

Check voltage between L1/L2 at the pump or at screws 2 & 4 of the pump relay.
