Trying to trouble shoot this and could use some help. We have a pool with a hot tub spillover when the pump is in Pool Mode. The water goes into the hot tub and circulates into the pool. When we go into spa mode (handled by remote and actuators that turn valves), the hot tub stops spilling over into the pool, and the water is circulated only in the hot tub.
Recently, the Raypak was giving a “Water Sw Open” error. When I was in spa mode, the pump emptied and it was sucking air. I cleaned and recharged the DE filter, and changed/lubed the o rings on suction side valve. Now, the water flow is totally fine and the Water Sw error is fixed, but ONLY when in pool mode. When I move the valve over to spa mode, the pump empties and starts sucking air, and the heater gives me the Water Sw Open error again and cuts off.
If I switch the valve back to pool mode (closing spa suction), the pump fills and the heater gets enough flow to stop the Water Sw error. The valves on the Skimmer and the Cleaner/Main are open half-way to about 10:00. (Are these valve settings correct?)
But, when I switch the valve back to the spa mode (close the skimmer and cleaner/main side, and open the spa suction) the pump empties again and the heater cuts out.
So, I believe I was able to isolate the issue to the Spa Suction side just by how the valves fill/empty the pump, but I don’t see or hear any leaks. I’ve tried the dish soap method, and the water hose method. And I’m not sure where to go from here. Any ideas?
Photos and videos included to better illustrate my issue. Happy to provide more info or photos pictures as requested. ( The pool valve normally has an actuator on it that mimics this - but I’ve removed it while I was trouble shooting. )
Thank you!
