have a sundance cameo spa with a century 850 LCD, about a 1998 model, and pump 2 came on and won't turn off. If you recycle the circuit breaker, pump 2 will come on, cannot be turned off, and it will stay on for about 30 minutes and then go off. Cannot turn it back on without recycling the circuit breaker. Currently we have disconnected the wires to pump 2. Any suggestions? All other functions good. Thanks!

One of two things, (in this order):

1. Topside control panel is defective...
2. Circuit board is gone.

For being the most expensive system to repair, I wish there were a magic bullet for the 850 series. There just isn't.

Let us know if you want to explore these options. Phone Number below:

does anyone know if a secondhand LCD side panel and circuit board for a Century 800 LCD, circuit board number 6600-040, would fit ours which is a 6600-0028? Or, could we possibly replace both?
