I am having an Aqualink RS6 issue with my booster pump turning itself on randomly for the last few weeks-I just go to my indoor control panel and turn the button off but it continues to come on and I can hear it turn itself off at times-with this covid19 crisis seems I am stuck to fix this for myself-when the booster was on I tried to turn it off at the spa switch, and the outdoor main control panel and it did not respond-from some of your posts I read it seems water in the switch at the spa might be an issue and my switch sits real close to if not in water-I had changed the spa switch out with my old pool guy about 7 years ago helping him pull in the cable but I do not remember why we had to change it-any thought on a temporary fix like removing the booster wire off its contact or something? or is it another issue I can do a temp fix?
