I have an aqua plus SWG and the unit runs for a while then turns off for a few seconds then back on. It will run for 10 to 15 minutes then do the same thing. I also noticed a few times that I got a NO COMMUNICATION notice on the LED....figured something was wrong but I would check on it later and it began running again. I had to replace the circuit board last summer along with putting in a new Cell as the other one was cracked. Thanks for any advise.
