I know very little about spas and even less about electricity so this is tough for me to take in.
But the heater and and one pump are working on my D1 2003 aurora. The tech came out and told me that the fuse needs to be switched out on the board and this is why the #2 pump isn't working.
The fuse is apparently hard wired onto the board and it can't be switched. He told me that the entire board had to be changed.
Does this sound right?
