I am all for you guys making money and have no problem paying for parts and labor. I've owned a auto repair business for 10 years and our saying was "you don't bring you're own eggs to waffle house."
The pump I needed was not in stock and the service tech indicated they would have to order it anyways and for me to let them know what I wanted to do. I decided to live without the 2nd pump for now. Yes $1300 was parts, labor, warranty and it is an OEM pump.
The wire into the control panel as best as I can tell is very secure and where it dislodged was from the main panel. Pins looked ok and I have had it off a second time to see if I put it on backwards, but it seems to only go in one way.
I have a call to have it serviced and my guess is somehow the main panel got damaged? All I know is when the spa boots up it triggers that light in seconds, so I know it is a hard fault.
