My CVA-24T valve actuator (right at main pump, valve to switch between pool suction or spa suction) has begun rotating back and forth without stopping. At one end stop it grinds, "bounces" back and forth, and then proceeds to the other stop, then starts all over again.
Yesterday, all was working fine. Ran the spa last night for the first time since the new year, no problems. This morning, no spillway from the spa, and I found the actuator freaking out. I've shut it all down, and had to throw the breaker on the Easy Touch panel to kill power to the actuator.
Of course it's a saturday and pool builder is closed (pool is 1.5 yrs. old). Any thoughts?
