Display shows Sn3 or SN3; spa may behave erratically or shut down.
Auxiliary Sensor Fault (Cabinet / Ambient / Optional Sensor)
—
Display shows dashes (---) or blank temperature reading; spa may not heat.
No Temperature Reading / Sensor Not Detected
Symptom
Discolored or cloudy water that does not clear with normal filtration in the MAAX spa.
Cloudy Water / Filtration Inefficiency
Symptom
Foamy water on the surface of the MAAX spa, especially when jets are running.
Excess Foam / Surfactant Contamination
Symptom
Jets are weak or there is very little water pressure from the MAAX spa jets.
Low Jet Pressure / Restricted Flow
Symptom
Ozone indicator is on but there is no ozone smell or visible bubbles from the ozone injector.
Ozone Generator Failure
Symptom
Pump runs but there is no water flow from jets; you may hear the motor humming.
Air-Locked or Cavitating Pump
Symptom
Spa is leaking water inside the equipment bay or from under the cabinet.
Plumbing Leak / Component Seal Failure
Symptom
Spa lights do not work or only some LEDs function; other spa functions are normal.
Lighting Circuit or LED Failure
Symptom
Spa makes a loud humming noise but the pump does not start and jets do not move water.
Stalled Pump / Failed Start Capacitor
Symptom
Spa makes loud grinding or screeching noises when the pump runs.
Pump Bearing Failure / Mechanical Wear
Symptom
Spa powers on but will not heat; water stays at or near ambient temperature with no heat-related error code.
No Heat Without Error Code
Symptom
Spa trips the GFCI breaker immediately or within a few seconds of turning on.
Ground Fault / Short Circuit
Symptom
Spa water cools down significantly between use cycles even though the set temperature is high.
Heat Loss / Insulation or Cover Problem
Symptom
Spa water has a strong burning or electrical smell coming from the equipment bay.
Overheating Electrical Component
Symptom
Spa will not power on at all; topside display is completely dead and pumps do not run.
No Power / Dead Spa
Symptom
Strong chemical or chlorine smell when opening the MAAX spa cover; users experience eye or skin irritation.
Water Chemistry Imbalance / Off-Gassing
Symptom
Topside control panel buttons do not respond or respond intermittently; display may be dim or missing segments.
Failed Topside Control Panel / Keypad
Symptom
Water has poor circulation in filter area; skimmer is not drawing debris effectively.
Skimmer / Suction Flow Problem
Symptom
Water is leaking from around a specific jet in the MAAX spa shell.
Jet Body or Gasket Leak
Symptom
Water temperature overshoots the set point by several degrees before the heater shuts off.
Temperature Overshoot / Control Calibration Issue
