Jacuzzi is a name synonymous with hot tubs. The company is 54 years old and purports on its website that they are responsible for starting the modern hot tub industry. While their hot tubs are energy-efficient and innovative, they will most likely need maintenance. The control panels on jacuzzi hot tubs will sometimes provide error codes, giving owners an idea of what to correct in order to get the hot tub back to normal working order.
This code indicates that the hot tub's water temperature is -6.67 degrees C or more below the set temperature. It will most likely appear when you first fill the tub, as the water is much colder than the temperature setting desired. Because the jets pump 1 and heater will automatically begin to operate, you will not need to correct anything.
The hot tub registers that a freeze condition is possible. Once again, you will not need to do anything, as the hot tub will start the jets pump 1 and heater. The unit does this to prevent pipes from freezing up in the hot tub, stopping when the freeze danger is over.
An open sensor or shorted sensor is possible with this error code. Most likely, the heater will not work and the spa itself deactivates. Additionally, the high-limit temperature sensor will not work, causing a potentially dangerous situation. You will need to contact a jacuzzi-qualified technician to correct this code.
Your hot tub's temperature sensor does not work. Due to the potentially dangerous conditions for the hot tub, you will need to contact a jacuzzi-qualified technician to correct this code.
FL1 and FL2
A flashing FL1 code indicates the flow switch malfunction filter is extremely dirty or the pump has an airlock problem. A flashing FL2 code indicates the flow switch is malfunctioning. Both codes can deactivate the hot tub's heater or jets pump 1. You can follow a few steps to correct this error code. Add water if needed to cover all jets while keeping the level below the lowest pillow in the tub. Clean or replace the clogged filter. Turn power off the unit and then turn it back on; this should reset the hot tub and correct the issue. Remove the filter cartridge; place a garden hose over the cartridge wall fitting (using a rag around the hose end in the tub) and turn on the water. Put the filter back in and check the control panel. If necessary, contact a jacuzzi-qualified technician to correct this code.
When this code appears, it indicates the water temperature is above proper limits. The jets pump 1 and circulation pump should be on, cycling water through the tub. Remove the spa cover to help cool the water and set the hot tub in the economy mode to help cool the water. If necessary, contact a jacuzzi-qualified technician to correct this code.
This code also means that water temperature is above proper limits. However, the hot tub will most likely deactivate at this point. The hot tub may have significant problems or possible damage, which will require you to contact a jacuzzi-qualified technician to correct.
