I just replaced the spa controls on a used tub and reconnected everything. When I turned on the power, the pump cycles on/off, not a continuous run it just pulses. I have checked for an air lock and loosened the fittings until water drained. If I select the 2nd speed the pump stays on a continuous run but the circulation at the jets seems very low.
I have removed the filter to ensure that I don't have a blockage there. I'm stumped and don't know where to go next. Help?
