Hi, new to the forum, very usefull, I am having trouble with FLow error, the flow switch seems to be working, I get a solid FL, which is supposed to mean that the switch is bad, but when I jiggle it a bit, it will start up the pump again, it will work for a day maybe, then I will get the message again, I wanted to change the switch, but when I disconnected it, the motor pump still works, I don't think that it should be, filters are clean.I hope I am explaining well. Beachcomber spa, balboa board, 2000 digital, 2004.If it is not the switch, how would I check the relay.I don't mind jiggling the switch now, but up here in winter temperature is mostly below freezing, I can't take a chance of the tub not running. Thanks
