PLEASE NOTE: The following corrective actions may be performed by the
spa owner. If the trouble cannot be corrected in the steps below, please
contact your authorized dealer for service. (Improper servicing by an unau-
thorized service provider or spa owner could result in damage not covered
by the warranty and could cause serious injury.)
EQUIPMENT WILL NOT OPERATE
• Check the control panel LCD window for diagnostic code.
• Check the circuit breaker on the main circuit panel.
INADEQUATE JET ACTION
• Be sure the slice valves are completely open.
• Check for obstruction or restrictions at suction guard(s) or filters, such as
leaves, dirty filters, etc.
• Check to ensure water is at proper level and add water if needed.
NO HEAT
• Check temperature displayed in the LCD window for desired temperature
setting.
• Inspect the filter cartridge for dirt and debris.

of self-diagnostic system checks and it can display a variety of messages in
the LCD window on the control panel.

WATR TOO HOT: One of the sensors has reached 110°F (43°C) . Do not en-
ter the water; contact your dealer for service.
