Our Pentair pool equipment is almost 3 years old now and runs on a wireless remote system. We just noticed that when we turn on the spa, the spa actuator turns as it should, the spa turns on ok, but the actuator doesn't seem to want to stop turning when it reaches the "other side". It looks like it a person banging their head. If we flip the switch on the back of the actuator it stops, but then it is no longer able to be controlled by the remote. Any ideas?
