So, I have no idea why my original post vanished! (Note:It was waiting for moderator approval. New posters require approval of their first post.)Here is the deal. Have a Hayward Heat-pump for the pool heating, and decided to open the pool alittle early this year (Pittsburgh). Well, the GFCI breaker keeps being thrown. Not sure what the deal could be. Should I contact the electrician or a Hayward service technician? I could use some assistance if this could be something I could handle as well! Please help a newbie! BTW, this is a new house and pool for me, but the heater was fine last year! I winterized as instructed! Re-plumbed with schedule 40 as well this year. Thoughts?
