Your spa has a self-diagnostic control system. The system will 
automatically display the following if a problem is detected. Always 
insist on genuine Jacuzzi replacement parts.

1.   
Priming Mode - M019: Each time the spa is powered up, it will enter 
a Priming Mode. The purpose of Priming Mode is to allow the user 
to run each pump and manually verify that the pumps are primed 
(air is purged) and water is owing. This typically requires observing 
the output of each pump separately and is generally not possible in 
normal operation. Priming Mode last about 4 minutes, but you can 
exit it earlier by pressing any Temp button. The heater is not allowed 
to run during Priming Mode.
2.   or   
Water Temperature is Unknown: After the pump has been running for 
1 minute, the temperature will be displayed.
3.   
Too Cold - Freeze Protection: A potential freeze condition has been 
detected, or the Aux Freeze Switch has closed, and all pumps are 
activated one at a time. All pumps are ON for at least 4 minutes 
after the potential freeze has ended, or when the Aux Freeze Switch 
opens. This is an operational message, not an error indication. 
Note: In some cases, pumps may turn on and off and the heater may 
operate during Freeze Protections.
4.   
Water is too Hot (OHS) - M029: DO NOT ENTER THE WATER. 
One of the water temp sensors has detected spa water temp 110°F 
(43.3°C) 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.
  WARNING: RISK OF HYPERTHERMIA (OVER-HEATING)
