My Pool was installed last year, PB closed the pool and i was able to open it myself about two weeks ago. Everything was going great till this week monday morning pumps wont start . i got email from my panel " MSP_DEV_COMM_LOSS,Comm Loss Device:10-01-13-b8-0c HUA:VSP" . I have two of the same pumps and they are on two pole 30amp gfci breaker. I checked and breaker was tripped. i fixed the breaker and everything was great , then again this morning i got a same email and breaker is tripped. Keep in mind pumps are not running , i have them shut down around 7pm and the come on at 7am. Here in northeast pumps are installed on an outlet so then can be winterized. When i installed the pumps i had sure the grounding is nice and tight. it has been little chilly overnight maybe moisture somewhere? All other forums i have read mainly circuit trips when pumps are on or speed changes. I have a call into hayward i am sure they wont be any help but in the mean time i am wondering is anyone come across something like this. I have attached pics of setup.
