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 for clogged stage 2 filter
(page 32-33). 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 41 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.
Circuit board temperature has exceeded acceptable
limit. This message will disappear when the circuit
board temperature drops below acceptable limit. If
condition persists, provide shade for equipment side
of hot tub.
FREEZE PROTECTION
A potential freeze condition has been detected. No
action is required. Pump(s) operate until the hot tub
is out of danger.
Note: This error commonly occurs
when the hot tub is first filled because tap water is
often very cold.
Communication between the control panel and/or
remote control panel and circuit board is faulty.
Contact your dealer or service organization.
"WATCHDOG" (hot tub is deactivated)
A problem has been detected which could cause
damage to the hot tub or its components. Contact
your dealer or service organization.
OPEN SENSOR (heater disabled) OR SHORTED
SENSOR (hot tub is deactivated)
