Spa Problems?

Spa’s can come up with a host of different secret coded messages telling you what it wants. Deep End Pools have compiled a list of all of the error codes we have come across to try and assist people who are having troubles with their spa.

Applied Computer Controls (ACC)

• CoLd : Temp in heater housing is below 40° F. Low speed / circ pump will operate continuously until the temp rises above 45° F.
• OH : Overheat. Spa temp over 108°. 
• HLoH : Hi Limit Over Heat. Hi limit sensor is disconnected, shorted, or spa temp is above 112° F.
• SEoP : Sensor open or disconnected. Heater disabled but spa operational.
• SESH : Sensor short, non functional. Heater disabled but spa operational.
• PSoC : Pressure switch open with circulation pump. 
• PSoL : Pressure switch open with low pump. 
• PSoH : Pressure switch open with high pump. 
• ToE : Time out error. Rare system error.

Balboa Error Codes

• pd: Power supply on battery
• OH: Sensors reading 112-118F
• OHH: Overheat. One sensor has detected 118º. Spa has shut down.
• OHS: Overheat.. One sensor has detected 110º. Spa has shut down.
• Flo: flow/pressure switch error
• Cool: Water temp 20 degrees below set point
• ICE: Potential freeze condition
• Sn1: Hi-limit sensor failure
• Sn3: Temp sensor malfunction
• Sna: Sensor A fail
• Snb: Sensor B fail
• SnS: Sensors out of balance. If alternating with temp, may be temporary condition.
• HFL: Substantial difference between temp sensors detected. Could indicate a flow problem
• LF: Persistent low flow problems. (Displays on the 5th occurrence of “HFL” message with 24 hours). Heater is shut down, but other spa functions run normally.
• dr: Inadequate flow in heater.
• dry: Inadequate flow in heater. (Displays on third occurrence of “dr” message)
• Pr: When spa is first actuated, it will go into Priming Mode
• —: Unknown water temp.
• Std: Spa operating in Standard Mode.
• Ecn: Spa operating in Economy Mode.
• SE: Spa operating in Standard-in-Economy Mode.
• ILOC: Interlock failure – possible pump/ozone spike

Brett Aqualine Error Codes

• OH: Temp exceeds 118 F
• 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: Improper electrical connection

CTI Error Codes

• thl/39: temp probe problem
• th2/current temp: temp probe problem
• th3/39: water temp below 39° F
• OH: water over 112° F. System will restart when temp. drops
• hot: water over 112° F. System will restart when temp. drops
• HL: High limit switch tripped

Dream Maker Error Codes

• OH: Overheat 108° F, spa is deactivated.
• FL: Flow. Pressure switch not working
• SN: Non functional high temperature sensor. Heater is deactivated
• F2: 4 hours daily filtration

• 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: Temp Set Celsius
• Tu: Temp Set F

Gecko

• AOH: Temp in Equipment compartment to high
• FLO: Pressure switch failure, switch open
• FLC: Pressure switch failure, switch closed
• FrE: Possible freeze condition
• Flashing Display
• 3 Flashing Dots
• 3 Flashing Dots & LED
• HL: Sensor measuring 119F
• Prr: Temp sensor failure
