I have a Aqua Plus with a EcoStar SP3400VSP pump. When I press the filter button on the control panel the pump will not come on. When a scroll through the default menu under filter it has "VSP Comm Error". On the pump it shows Comm Bus "offline. I have tried the following: turned breakers off let sit for 30 sec on turned back on, check the continuity of the control wires between the controller and the pump and connect all others connections . I can control the pump using the timer on the pump and the pump work fine. From the research I have done it looks like either the display board on the controll or the display board on the pump. Any suggestion on how to target which one it my be??
