13.0 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. Following is a list-
ing of all the possible messages along with their meanings:
MESSAGE MEANING
Overheat Protection (Heater is deactivated, pump’s
low speed is activated). Water temperature is
above acceptable limits. Do not enter the water!
Remove hot tub cover to speed cooling. See
“WATER IS TOO HOT” on page 41. If condition
persists, contact your dealer or authorized service
center.
If the hot tub water is more than 20 °F cooler
than the temperature setpoint, the low speed
pump #1 and heater will automatically activate to
provide freeze protection. The hot tub will stay in
this mode until the water temperature reaches 15
degrees below the set temperature. No corrective
action is necessary.
FLOW SWITCH (Heater is deactivated. Pump may
also be deactivated). Proper flow of water is inhibit-
ed or a flow switch has malfunctioned. Check for
proper water level and check for clogged stage 2 fil-
ter (page 30-31). Contact your dealer or service
organization.
*NOTE: THIS MESSAGE CAN ALSO APPEAR IF THE PUMP HAS NOT
REGAINED PRIME AFTER THE HOT TUB HAS BEEN DRAINED AND
REFILLED. IF YOU SUSPECT THAT THIS IS THE CASE, SEE THE
INSTRUCTIONS ON PAGE 40 UNDER “PUMP DOES NOT OPERATE...”
Panel sensors have been pressed too many times in
a short period of time. Because this could cause
excessive wear on equipment components, panel
sensors are temporarily deactivated. Panel sensors
will automatically re-activate if no sensor is pressed
for 30 seconds.
