Display shows FL, spa may not heat, circulation pump may run continuously or cycle.
Flow Switch Open / Insufficient Circulation
FLO
Control panel displays FLO or FL, jets may run briefly then shut off, heater does not come on, possible blinking heat indicator.
Low Water Flow / Flow Switch Open
HL
Display shows HL or HLo, spa may shut down heater but pumps still operate.
High-Limit Sensor Trip (Non-Latching)
Htr
Display shows HTR or HEAT FAIL; water does not reach the set temperature.
Heater Failure / No Heat Output
ICE
Display shows ICE or FR; pumps run periodically even when the spa is not in use.
Freeze Protection Mode
LOC
Display shows LOC or PANEL LOCK; buttons do not respond, or only limited functions work.
Control Panel Lock / Child Lock Enabled
OH
Display shows OH or OHH, spa shuts down, pumps may run briefly then stop, water feels excessively hot.
Overheat Condition / High-Limit Trip
OHH
Display shows OHH, spa shuts down completely, no heat, pumps may not respond until power is cycled.
Critical Overheat / High-Limit Lockout
P1
Display shows P1 ERROR or P1 FAIL; the primary jet pump does not start or trips the breaker.
Pump 1 Failure / Overcurrent
P2
Display shows P2 ERROR or P2 FAIL; the secondary jet pump does not run or hums then shuts off.
Pump 2 Failure / Overload
SLP
Display shows SLP or SLEEP; the spa temperature drops between cycles, and heat is only active during programmed times.
Sleep Mode Active
Sn1
Display shows Sn1, SN1, or SENSOR 1, spa may not heat or may shut down heater.
Water Temperature Sensor Fault
Sn2
Display shows Sn2, SN2, or SENSOR 2, spa may shut down heater or display incorrect temperature.
High-Limit Sensor Fault
SNS
Display shows SNS or SENSOR; spa may not heat and may cycle pumps.
General Sensor Error (Temperature/High-Limit Mismatch)
— —
The display is blank or shows only dashes; the spa does not respond to button presses.
Control Panel Communication Loss
Symptom
A strong chemical or burning plastic smell emanates from the equipment bay, and components appear discolored.
Overheating Electrical Component
Symptom
Air controls (venturi knobs) do not introduce air; jets feel flat with no bubbles, even when air valves are open.
Air Induction Failure
Symptom
Filter cycles do not run at the programmed times, or spa seems to skip filtration.
Filtration Cycle Programming Issue
Symptom
Jets are weak, or some seats have very little water pressure even when the pump is on high speed.
Low Jet Pressure / Restricted Flow
Symptom
Loud grinding, squealing, or rattling noise from the pump area when jets are on.
Pump Bearing or Cavitation Noise
Symptom
One or more jets do not flow at all, while others work normally.
Individual Jet Blockage or Shut-Off
Symptom
Ozone generator not bubbling or no ozone smell; water quality declines faster than usual.
Ozone System Failure
Symptom
Spa cabinet or shell vibrates excessively when pumps are on high speed.
Excessive Vibration / Pump Misalignment
Symptom
Spa lights do not work, but all other functions are normal.
Lighting Circuit Failure
Symptom
Spa water foams excessively when jets are on.
Foaming Water / Surfactant Buildup
Symptom
Spa water has a strong musty or rotten egg odor.
Contaminated Water / Biofilm Growth
Symptom
Spa water is not circulating during filtration cycles, but jets work when manually activated.
Circulation Pump Not Running
Symptom
The spa does not heat; the temperature stays well below the set point, but pumps and jets work normally, and no heater error code is displayed.
No Heat Without Error Code
Symptom
The spa is leaking water into the equipment bay or from under the cabinet.
Plumbing Leak / Component Seal Failure
Symptom
The spa trips the GFCI breaker immediately or within a few seconds of turning on.
Ground Fault / Electrical Leakage
Symptom
The spa will not power on at all; there are no lights on the control panel and no pump activity.
No Power / Dead Spa
Symptom
Topside control buttons are unresponsive, or only some buttons work intermittently.
Keypad / Topside Control Failure
Symptom
Water continuously dribbles from one or more jets even when pumps are off.
Backflow / Check Valve or Diverter Leak
Symptom
Water temperature fluctuates widely—sometimes too hot, sometimes too cool—without changing settings.
