Hi I have a 2005 Aegean 250 spa with a Balboa 2000 LE Control Box w/ M-7 Technology control box. A few weeks ago the spa started to surge on pump 1. I changed the water, bought new filters and cleaned the intake grills. The water level has always been at the correct level but still I get sporadic surging from pump 1. If I turn off the spa and then turn it on again this cures the problem in the short term but a few days it starts again. I have just turned the pressed the button on the top control panel for pump 1 and this stopped the pump surging but there was a clicking from the control box that sounded like a solenoid clicking on and off. The light on the top panel flashed in time with the clicking from the control box. I do not know what the problem is so please help. Regards
