Have a Dynasty - Garden Leisure Spa - in the last month - the pump goes on for 10 seconds - off then on then off - then maybe an hour later - goes on for the normal cycle - maintains the correct temperature - then later it starts to go on and off again. I have had the factory people out here three times and they don't have a clue as to how to correct. We love our spa and my wife and I use it every day to relax at night - any suggestions Thx Max
