driven33 Posted May 14, 2016 Report Share Posted May 14, 2016 So I have a balboa vs system installed in my spa with two pumps. Upon turning it on, it cycles as expected, and then runs does what it should. If it's up to temp, both pumps shut off. If it needs to heat, one pump will continue to fun to draw water through the heater. The problem starts a short time in. The larger pump stops becoming responsive to the panel. The control panel "clicks" like a relay is trying to cycle. Every 5-10 minutes, the big pump will rapidly cycle on and off, then shut down again. Any suggestions? Thanks.
