After 30 minutes, the blower to the spa shut off automatically. I reviewed the pool programs from the control box inside my house and saw that this was supposed to happen. However, now the water in my spa is draining into my pool (I can feel the suction coming from the intake/outake valves on the sides of the spa). I tried refilling the spa twice already from the outside control panel (by turning on the filter and "spa fill" controls, as instructed by the conntrol panel that is attached to my house beside my pool. However, each time I did this, the spa filled to the level I wanted it filled to, but then started to drain again once I turned the "spa fill" feature and filter off. It's a slow drain, but a drain nevertheless. Any ideas on why this is happening and how can I stop it so the water level in the spa will remain above the intake/outake valves........or better yet, remain at the top of the spa where I like it?
