LCD DIAGNOSTIC MESSAGES
The advanced technology built into the spa allows it
to perform a number of self-diagnostic system
checks and it can display a variety of messages in
the LCD window on the control panel.
CL:
This appears every 30 days as a reminder to clean
the filter. (See INSTALLATION INSTRUCTIONS, Filter
Cartridge(s).)
CH:
This appears every 90 days as a reminder to drain
and refill the spa. (See SPA MAINTENANCE,
Draining and Filling the Spa.)
FL:
A pressure switch may have malfunctioned.
Contact you dealer for service.
HFL or drY:
The filter may be plugged.
The spa water level may be too low.
A shut-off valve may be closed.
ICE:
Freeze protection has been activated. Contact
your dealer for service.
OH:
Over heat protection. If a malfunction occurs and
the spa water reaches 112°F (44°C), the system
completely shuts down. In such a condition, DO
NOT ENTER THE WATER. Turn off all power to
the spa and contact your dealer for service. Sev-
eral conditions could lead to overheating, for
example, low water level, shut-off valves closed
while heater is on, dirty filter, and restriction in the
plumbing lines. After the power if turned back on,
the spa will not restart itself until the water tem-
perature within the spa drops to a lower, predeter-
mined temperature. As a double safety feature, a
secondary high-limit sensor shuts the system off if
the water temperature in the heater housing
reaches 118°F (48°C). In this case, the spa may be
restarted by pressing any panel pad after the water
has cooled to 110°F (42°C). If the switch trips
repeatedly, do not use the spa and contact your
dealer for service.
