Find out what your spa is trying to tell you. The codes on the upper control can tell you a lot about what is going on with your spa. If you can't find the actual code displayed on your topside, give us a call.

NOTE:  Manufacturers change error codes periodically, this is a guide only. The codes listed below may differ from your spa topside codes. The codes listed below may not be complete, check with your spa manufacturer for the most current codes.

•  Balboa

pd = Power supply, unit running on battery backup
OH = Sensors reading 112-118 Degrees
Flo = Improper flow or pressure switch malfunction
Cool = Water temp 20 degrees below set point
ICE = Potential freeze condition has been detected
Sn1 = Hi-limit sensor malfunction
Sn3 = Temp sensor malfunction
ILOC = Interlock failure - possible pump or ozone spike
(---) =Unknown water temperature. (Displays when Spa is first powered up after refill).

•  Brett Aqualine

OH = Temp exceeds 118 degrees
Fr = Freeze condition - temp below 40 degrees
FL = Pressure switch failure
EO = Shorted temp sensor
E1 = Open temp sensor
E2 = Shorted hi-limit sensor
E3 = Open hi-limit sensor
E4 = Shorted flow switch
E7 = Improperelectrical connection

•  Gecko

FLO = Pressure switch failure, switch open
FLC = Pressure switch failure, switch closed
Prr = Temp sensor failure
Prh = Hi-limit sensor failure
HL = Sensor measuring 119 degrees
FrE = Possible freeze condition detected

•  Sundance

ILOC = Interlock failure - possible pump or ozone spike
FLO = Pressure switch malfunction or Flow switch malfunction (system specific)
Hold = Panel buttons pressed to many times to quickly
HOT = PCB temperature above acceptable limit - air blower on
ICE = Potential freeze condition
Pnl = Communication between PCB and panel interrupted
Sn1 = Hi-limit sensor failure
Sn3 = Temp sensor failure
(----) = "WATCHDOG" (spa is deactivated) A problem has been detected.

Your error codes may be different than shown. For system specific codes click here to download the manual for your spa.

•  Hurricane

PS = Flow or pressure switch failure
SH = Shorted sensor
OP = Open Sensor Degrees
LO = Temp below 60 degrees - freeze
HL = Temp above 118 degrees

•  Jacuzzi

OH = Overheat Protection (Heater is deactivated, pumps low speed is activated).
COOL = Spa water is more than 20 degF cooler than the temperature setpoint.
FLO* = Flow Switch (heater is deactivated. Pump may also be deactivated).
Hold = Panel sensors have been pressed too many times in a short period of time.
HOT = Circuit Board temperature has exceeded acceptable limit.
ICE = FREEZE PROTECTION No action is necessary.
I CE2 = FFREEZE PROTECTION No action is necessary.
PnL = Communication between the panel and circuit board is faulty.
(----) = "WATCHDOG" (spa is deactivated) A problem has been detected.
Sn1 = OPEN SENSOR (heater is deactivated) or SHORTED SENSOR (spa is deactivated).
Sn3 = OPEN SENSOR OR SHORTED SENSOR ( heater disabled).
FLO2 = CLOSED OR SHORTED FLOW SWITCH ON SYSTEM START UP.

•  ACC (Applied Computer Controls)

SEoP = Sensor open or disconnected and SmarTouch cannot determine the spa temperature. The heater is disabled but the spa is operational. The sensor must be replaced or reconnected for the message to go away.
SESH = Sensor short. The sensor is shorted and is nonfunctional. Temperature cannot be determined, the heater is disabled, but the spa is still operational. Sensor must be replaced to get rid of this message.
PSoC, PSoL, PSoH = Pressure Switch Open with circulating, Low or High pump(s). The pressure switch is a device sensative to pressure inside the heater manifold. Pressure in the heater manifold is generated by a pump pushing water through the manifold. If one pump is running and the pressure switch does not sense any pressure then there is an indication of no water flow. To prevent the heater from being turned on when there is no water running through, the heater is turned off and one of these messages will be displayed indicating which pump is supposed to be running.
ToE = Time Out Error. It is not likely that you will ever see this error. It indicates that the system's heartbeat is out of control, all devices will be shut down and the spa is unusable. This message will rarely ever occur, if it does, please contact Applied Computer Controls.

•  Hydro-Quip

C = Celsius
CL = Current Time of Day
ECdu = Economy Mode Duration
Econ = Economy Mode Turn On
F = Fahrenheit
Fldu = Filter Cycle Duration
Flon = Filter Cycle Turn On
FLC = Pressure Switch Alarm
FLO = Pressure Switch Alarm
FrEE = Freeze Protection Alarm
HL = High Temperature Alarm
Loc = Panel / Keypad Locked
PrH = Temperature Sensors Alarm
Prr = Temperature Sensors Alarm
Tu = Temperature Set Celsius
Tu = Temperature Set Fahrenheit
