I have a Jandy Aquapure RS 1400, with a spa side switch. Right now when the pool program triggers the pool pump to turn on, it turns on, but instantly changes to Spa mode, and then the Spa runs instead of the pool. I can only run the pool mode from Service mode. I've checked the relay switches & they appear to be fine. I disconnected the Spa Switch at the Jandy box, but that didn't work either, the pool still won't run without instantly changing back to Spa mode. What should I try next???
