15.0 Troubleshooting - Display Messages

There are a number of unique functions designed into your
Sundance hot tub to protect it from damage and/or to aid in
troubleshooting. The indicator light located on the front cabinet
panel of the spa is an early detection system that will notify
you when the spa needs immediate attention. A solid white
light indicates that all operations are normal. A solid red light indicates
that immediate attention is required to clear or fix an error code. Follow-
ing is a listing of all the possible messages along with their meanings.
Always insist on genuine Sundance replacement parts.
