HAVE YOU HAD ANY LIGHTNING STRIKES?

SOURCE: Why am I getting a 6700 REV C message on my AquaLink RS6 home spa

I had the same issue, but only after I pressed the reset button on the side of the panel. After a couple of days of troubleshooting, I found a small nick in the wiring from the outdoor unit to the indoor paneI. I turned off the breakers to the pool equipment, rerouted a new cat5 cable, but cat3 will work just as well, wired it up and all was good. A local pool guy wanted to charge me about $2000 to replace both units. I spent less than $5.

Good luck

There SHOULD be a valve that you can close to disable the spa.
