So frustrating...We have a Saniclear 40 SWAG. Of course it is 3 months out of warranty! When you turn the system on after just a few minutes all of the lights go out...nothing blinking, no power light. Can the flow sensor cause the entire system to shut down...even power? I have replaced the fuse, the cel is fine, salt in the pool is good as well as all chemistry. We have a whole house surge protector so I don't think it would be that. Any thoughts much appreciated. I called the local rep. and he said he was checking on it but haven't heard back from him...guess I'm impatient, but I don't want the pool to turn green!
