This tub came with the house we purchased in February. It had a couple of leaks and bad heater. We replaced the heater, an one pump head. This included the heater high limit switch. We also had to cut out the secondary drain pipe due to location and cap off. The previous owner and let things freeze up during a winter two years ago.
The spa heats fine and when the number 2 jets are turned on they run for ever. When the Number 1 jet is turned on, they run for maybe a minute and the tub shuts down.
What could be the issue? Help
