The water is too hot – M029
The system has detected a spa water temp of 110°F (43.3°C) or more, and spa functions are disabled. System will auto reset
when the spa water temp is below 108°F (42.2°C). Check for extended pump operation or high ambient temp.
Heater-Related
The water flow is low – M016
There may not be enough water flow through the heater to carry the heat away from the heating element. Heater start up will
begin again after about 1 min. See "Flow Related Checks" below.
The water flow has failed* – M017
There is not enough water flow through the heater to carry the heat away from the heating element and the heater has been
disabled. See "Flow Related Checks" below. After the problem has been resolved, you must press any button to reset and begin
heater start up.
The heater may be dry* – M028
Possible dry heater, or not enough water in the heater to start it. The spa is shut down for 15 min. Press any button to reset the
heater start-up. See "Flow Related Checks" below.
The heater is dry* – M027
There is not enough water in the heater to start it. The spa is shut down. After the problem has been resolved, you must clear the
message to restart heater start up. See "Flow Related Checks" below.
The heater is too hot* – M030
One of the water temp sensors has detected 118°f (47.8°C) in the heater and the spa is shut down. You must clear the message
when water is below 108°f (42.2°C). See "Flow Related Checks" below.
Flow-Related Checks
Check for low water level, suction flow restrictions, closed valves, trapped air, too many closed jets and pump prime. On some
systems, even when spa is shut down by an error condition, some equipment may occasionally turn on to continue monitoring
temperature or if freeze protection is needed.
Sensor-Related
Sensors are out of sync – M015
The temperature sensors MAY be out of sync by 2°F or 3°F. Call for Service.
Sensors are out of sync -- Call for service* – M026
The temperature sensors ARE out of sync. The fault above has been established for at least 1 hour. Call for service.
Sensor A Fault, Senor B Fault – Sensor A: M031, Sensor B: M032
A temperature sensor or sensor circuit has failed. Call for Service.
