14.0 Error Conditions/Error Messages

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.

14.1 Summer Logic

When the actual spa water temperature reaches 2°F (1°C) above the set temperature, the spa goes into “summer logic.”

The circulation pump will turn off automatically, if running, to avoid adding additional heat to the water, eventually creating an overheat condition. This setting is not user-programmable.

Note: Summer logic does not take effect until the spa water temperature reaches 95°F (35°C). This condition is more likely in excessively hot weather. Remember, the spa’s ability to cool is directly affected by the ambient temperature. An excessively hot ambient temperature may prevent the spa from cooling down because it’s fully insulated construction is designed to retain heat and minimize operating costs.

14.2 Panel Displays COL

Cool Condition - Temperature has dropped 20°F (11°C) below the current set temperature. Jets pump 1 and the heater have been activated to bring the temperature within 15°F (8°C) of the set temperature. No corrective action is required!

Note: This condition is common during first time fill ups or during refills since tap water is often very cold. “COL” will only appear when the spa is in Economy mode.

14.3 Panel Displays ICE

Freeze Protection - A potential freeze condition has been detected. No action is required. Jets Pump 1 and heater will activate to circulate and warm water through the plumbing until spa is out of danger. See “Winterizing” (page 42).

14.4 Panel Displays SN1

Open sensor (heater is disabled) or shorted sensor (spa is deactivated). The high-limit temperature sensor is not functioning. Contact your authorized Jacuzzi dealer or qualified service technician.

14.5 Panel Displays SN2

Open or shorted sensor (heater disabled). The temperature sensor is not functioning. Contact your authorized Jacuzzi dealer or qualified service technician.

14.6 Panel Displays BLB

UV bulb needs to be replaced. The message will flash between “blb” and the water temperature. The countdown timer for the UV bulb needs to be reset (page 33). A new UV bulb can be purchased from a local Jacuzzi dealer.
