Hi, everything was working fine up until about a week ago, when we noticed that the pump would not turn on when we switched to spa mode. Auto valves move correctly, and the heater turns on, but no pump to circulate the water. Pump works fine in pool mode, but shuts off when we hit the Spa button on the Pentair intellitouch 520138 control panel. Also, if I manually move the valves over to the spa when in pool mode, everything works. It seems like some programming glitch on the intellitouch. Any thoughts?
