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.
HH: Overheat. The spa has shut down. DO NOT
ENTER THE WATER. Contact your dealer for service.
OH: Overheat protection. If a malfunction occurs and the
spa water reaches 110°F (43°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. Several 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 temperature within the
spa drops to a lower, predetermined 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.
IC: Ice. Potential freeze condition detected.
SA: Spa is shut down. Sensor plugged into sensor “A”
jack is not working.
Sb: Spa is shut down. Sensor plugged into sensor “B”
jack is not working.
Sn: A sensor has malfunctioned. If alternating with spa
temperature, it may just be a temporary condition. If
flashing by itself, spa is shut down. Contact your dealer
for service.
HL: A significant difference between tempreature
sensors has been detected. This could indicate a flow
problem. Check water level in spa and refill if necessary. If
water level is okay, make sure the pumps have been
primed.
LF: Persistent low flow problems. Heater is shut down,
but other spa functions continue to run normally. Check
water level and refill if necessary. Contact your dealer for
service.
dr: Possible inadequate water, poor flow, or air bubbles
detected in the heater. Spa is shut down for 15 minutes.
Check water level and refill if necessary. If okay, check
that pumps have been primed. Press any button to reset.
dY: Inadequate water detected in heater. Spa is shut
down. follow directions for “dr” message.
