I’ve recently started having issues switching to spa mode on my pool. When I switch to spa mode the return valve is slow to respond. The intake valve starts moving immediately but the return valve is delayed. Sometimes it’s just a few seconds but other times it’s minutes. A couple of time I turned on spa mode only to go out later and find my spa was half empty before the valve finally switched. Any suggestions? Jandy automation system. I’ll attach an image of the valve.
