My hayward heater is in its 3rd season. I have it cleaned by service company upon opening. In April after opening heater would come on go off with a H5 . Since the pool is on the same 220 breaker as pool it would turn pool off . I had electrician check breakers snd isolated it was the heater . The service company came and said wires were getting wet and adjusted something. Note it seems to happen after it rains. Sunny weather no problem. Heater is still turning off now code is IF two service calls by different companies and they are sll stumped they are hayward certified . Again it only happens after raining once it dries it works . The service companies want to replace gas values , flow switch etc . Any thoughts from experienced folks on what the problem could be ?
