Cal Spas Error Codes

These are the error codes and display messages that all 2015 Spa models may display except for the Platinum Spas, along with what they mean and the action required:

Message Meaning Action Required
PUMPS PURGE AIR Priming Mode-Every time that the spa unit is started (powered up), it enters the Priming Mode. Priming Mode functions to enable you to run the pumps and manually verify that water is flowing and that air is purged from pumps. This verification is typically not possible in normal operating mode of the spa and requires the separate observation of the output of each pump. Keep in mind that the spa will turn on with Jets 1 during Priming Mode if it has a Circ Pump. When you exit the Priming Mode, the Circ Pump runs by itself.Priming Mode goes on for 4 minutes, but can be exited earlier by depressing the Temp button. During Priming Mode, the heater is not permitted to run.
– – –°F – – –°C Means that the temperature of the water is unknown. The temperature will be displayed after the pump runs for 1 minute. The pumps may cycle on and off in some cases, and the heater may function during Freeze Protection. No action required.
42F Too Cold Freeze Protection – Means The equipment has detected a potentially freezing condition to the unit. All of the blower and pump devices are activated.  These devices stay on for at least 4 min after the potential freeze condition ends. In some examples, the heater may operate, and the pumps may cycle on and off during Freeze Protection. This is not an error indication, but an operational message. No action required.
Water is too Hot (OHS) Means that a water temperature sensor has detected water temperatures 110°F (43.3°C). Spa functioning is then disabled. Once water temperature is below 108°F (42.2°C), the System will then auto reset. Check for high ambient temperatures or extended pump operation.
SFTY TRIP This is a safety trip error message which means the switch to the vacuum switch has closed. This situation happens with suction issues or a possible entrapment situation avoided. Note that all spas don’t have this feature. Clear any blockages or debris covering the drain or Cal Spa filter, then reset by depressing any button located on the top side panel.
HTR FLOW LOSS Indicates possibility of inadequate water flow to heater to carry heat away from the spa unit’s heating element. Check to determine conditions such as closed valves, suction flow restrictions, pump prime, low water level, trapped air and too many closed jets. Heater starts again after 1 min.
HTR FLOW FAIL Heater Flow is Reduced-means there is inadequate water flow to heater to carry heat away from the spa unit’s heating element. The heater is disabled. Check to determine conditions such as closed valves, suction flow restrictions, pump prime, low water level, trapped air and too many closed jets. Heater starts again after 1 min.
HTR MAY BE DRY – WAIT Means there isn’t enough water to start it or a possibility of a dry heater – spa is shut down for 15 minutes. Check to determine conditions such as closed valves, suction flow restrictions, pump prime, low water level, trapped air and too many closed jets. You can depress any button to reset theheater start-up.
HTR DRY Indicates that there isn’t a sufficient amount of water in the heater in order to start it. The system shuts the spa down. Check to determine conditions such as closed valves, suction flow restrictions, pump prime, low water level, trapped air and too many closed jets. Once the issue is resolved, clear the message in order to restart the heater startup.
HTR TOO HOT Means that a temperature sensor detected temperatures that are too hot in the heater ( 118°f /47.8°C). The system shuts the spa down. Check to determine conditions such as closed valves, suction flow restrictions, pump prime, low water level, trapped air and too many closed jets. Reset once the water level goes below 108°f (42.2°C) by pressing any button.
PRES BTTN TO RSET Means that the spa unit will need to be reset. This message might appear with another message. Reset by depressing any button located on the top side panel.
102F SNSR BALANCE The temperature sensors are not in balance and are more than likely are out of sync by 2°F – 3°F. Put in a service call.
SNSR SYNC with call for service message Indicates that sensors that monitor temps are not in balance and ARE out of sync. Put in a service call.
SNSR A with call for service messageSNSR B with call for service message Indicates sensor or sensor circuit failure(s). Put in a service call.
NO COMM The spa unit control panel isn’t receiving the communication from its system. Put in a service call.
102°T °F or °C is replaced by °TThe spa unit’s control system is operating in Test Mode. Put in a service call.
STUK PUMP The pump is likely stuck ONWater most likely is overheated. DO NOT GO IN THE WATER. Turn off the power to the spa unit. Call your service supplier or dealer
