I have a Jandy PDA PS/4 and used the spa last night. The battery on it was low when I went to turn it off and return to pool mode. It seemed to work as the pool pump the spa shut off & the pool pump came back on. However, today when the pool came on at the set time, the spa is running, but overflowing into the pool (which makes me think a valve is stuck) but the pool panel and the PDA both say "pool mode" even though the spa is clearly running. I've tried resetting the equipment at the control panel. The pool comes back on, says the pool pump is on, but it is actually the spa running. Any ideas how I can either reset it or if you think it's a valve problem?
