Topside Error Codes

Home Owners -use of our online catalog is free for reference only. We only sell to qualified wholesale customers.

The following are a few error codes you may get on topsides.
Brett
  • 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 = Improper electrical connection
  • FC = Filter Cycle
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.
 
Gecko (New Style)
  • 32° = Temp sensor not detected
  • 112° Flashing = Water too hot; let cool down & system will reset itself @ 109°
  • 3 Flashing dots on display = water fl ow problem check for closed valves, dirty filters, water level, pump/wetend operation / defective pressure switch.
  • Flashing dots & light lit on circuit board = Hi-limit trip. Reset power to clear
  • Temp reads correct water temp = Good; if incorrect replace sensor
  • Inverted Display = Press Filter key for 5 seconds (certain models only)
  • Pump starts by itself for 1 minute on several occasions & Filter indicator flashing = Smart Winter Mode not an error but a feature (Freeze protection)
  • Filter cycle has stopped & “Filter” indicator is flashing not an error but a feature; either the filter cycle is in a 40 minute time-out to avoid ozonater activation while spa is being used or the system has cancelled a filter cycle after 3 hours because
    water temp exceeds set point by more than 2°
  • “Heater” indicator fl ashes when pump is on high speed. Not an error but a feature. The system is turning off the heater when pump is on high speed to limit amperage draw (jumper 1 set to “LC” mode)
  • Temperature displays water temp “C°” or “F°”. Simply hold light button for 5 seconds to toggle.
  • Technical note: After making any changes to any P.C.B or control system; RESET the Breaker
Gecko (Old Style)
  • FLO = Pressure switch open
  • FLC = Pressure switch closed
  • Prr = temp sensor failure
  • Prh = Hi-limit sensor failure
  • FrE = Possible freeze condition
 
Hurricane
  • PS = Flow or pressure Switch failure
  • SH = Shorted sensor
  • OP = Open sensor
  • LO = Temp below 60 degrees – freeze
  • HL = Temp above 118 degrees
Hercules
  • OH = Spa temp exceeds Acceptable limits
  • FLO = Flow problem
  • ICE = Freeze condition detected
  • SN1 = Hi-limit sensor failure
  • SN2 = Temp sensor failure
 
Lennovator
  • “SP” = SPA MODE ; not an error
  • “PO” = POOL MODE; not an error
  • “NC” = No Communication With Master Control Unit
  • “- - “ = Data Being Sent To Master Control Unit
  • “OP” = Temperature Sensor Failure-open
  • “SH” = Temperature Sensor Failure-shorted
  • “OH” = Warning, Water Temperature Over 120°f
  • “IP” = Insufficient Power
  • “FP” = Freeze Point
  • Temperature: Set Point & Actual Water Temp
  • Temperature Flashing On & Off - Warning - Water temperature high (109°-120°F)
Hydro Quip
  • FLO = Pressure switch open when system expects it to be closed
  • FLC = Pressure switch closed when system expects it to be open
  • HL = The spa water has exceeded 119 degrees
  • OH = The spa water has exceeded 112 degrees
  • Prr = Temperature sensor malfunction
 
Spa Builders LX 10/15
  • Sn1 / 01 Nonfunctional /open high temperature sensor. Heater deactivated
  • Sn2 / 02 Nonfunctional /open temperature sensor. Heater deactivated
  • FL1 / 03 Pressure switch not closed when pump is running and heater is trying to heat, Heater is also deactivated
  • FL2 / 04 Pressure switch is closed when pump is off
  • COL / 05 Cool Condition Water Temp has dropped 20° below set temperature low speed pump & heater will activate to bring temperature to within 15° of preset; only works in economy mode
  • ICE = Freeze condition. Water temp has reached 55°; pump & heater are activated
  • OH = Water temp above acceptable limits (above 110°)
  • “---” = Watchdog Water temp above acceptable limits (above 118°). Potential damage to spa equipment. Possible sensor, transformer, topside or circuit board failure
Sundance
  • ILOC = Interlock failure
  • OH = Sensor indicates water temp above acceptable limits
  • FLO = Pressure Switch malfunction
  • Hold = Panel buttons pressed too many times to quickly
  • HOT-– Air blower on
  • ICE = Freeze condition
  • PnL = Communication error between circuit board & panel
  • Sn1 = Hi-limit sensor malfunction
  • Sn3 = Temp sensor malfunction
  • “-----” = Watch dog – Water temp above acceptable limits (above 118°). Potential damage to spa equipment. Possible sensor, transformer, topside or circuit board failure
 
 

 

Vita
  • HiLi = Water temp over acceptable limit
  • BJ2P = Pump/Blower purge – Normal condition
  • FP = Freeze protect – temp under acceptable limit
  • SS=0; SS=S; LS=O; LS=S = Multiple causes; Open sensors, bad connection to panel, Improper voltage, etc.
