In my 2003 Sweetwater I have a 2 pump system (3 if you include the 24/7 circulation pump). At start up, pump 2 (1 speed) runs constantly and can't be controled by top side control. I am also in the process of troubleshooting the circulation pump not running. Does any one have any ideas why pump 2 would run non-stop?

 

It's probably a bad controller. Try shutting off the breakers for a minute and see if it'll reset.
