Hot Springs Trouble Shooting Guide 

IssuePossible ReasonsHot Springs Hot Tub Troble Shooting Solutions
Hot Tub Not Working
“Summer Logic” occurs when the actual water temp for the spa climbs to 2°F (1°C) above set temperatures and is more likely in extremely hot weather. The condition causes the circulation pump to turn off automatically if it’s running in order to avoid adding additional heat to spa water that could cause “Overheat” conditions. This setting is not user-programmable.This condition does not kick in until the water temperature climbs to 95°F (35°C). The spa system’s ability to cool itself down is directly affected by ambient temperatures. Very hot summer ambient temperatures can prevent the spa unit from cooling because its insulated construction is designed to minimize operating costs and hold in heat.
OH
One of the sensors detected that the water in the hot tub is 112°F (44°C). Stands for “Overheat”- and the tub shuts down because water temp is too hot. Temperature is not safe. The circ. pump will stop functioning to reduce frictional heating when water temp reaches 2°F (1°C) more than the set temperature.DO NOT GET INTO THE WATER! Take off the spa cover to allow the water to cool down to fix the situation. Caution: Do not leave this cover off when children are present. Shut the power down to the hot tub and contact the dealer or service technician if the problem continues.
Sn1
Stands for “Sensor 1” and displays when the high-limit sensor is malfunctioning. Indicates a shorted sensor and spa is shut down or an open sensor and heater is disabled.Contact dealer or a service technician.
Sn2
Stands for “Sensor 2” and displays when the temperature sensor is malfunctioning. Indicates a shorted sensor and the heater is disabled.Contact dealer or a service technician.
FL1 or FL2 (Flashing)
When FL1 code starts flashing it means the flow switch is malfunctioning and stuck open-likely because of a dirty filter or because there is an air lock problem at the circulation pump intake.When FL2 code starts flashing it means the flow switch isn’t working and it is stuck closed. In both cases, the spa heater will deactivate.· In both cases, the spa heater will deactivate and main pump # 1 may do the same.· The issue is caused by an excessively dirty filter cartridge that interrupts the flow of water leading to “air lock” conditions at the pump and malfunction of the flow switch.1. Check to see if the water level is below the lowest pillow but above the jets. Add water if needed.2. Check for dirty or clogged filter cartridge.3. a) Remove filter cartridge in order to purge the air lock from the circulation pump intake. b) Hold a garden hose over filter cartridge wall fitting and utilize a rag to make a seal around hose end. c) Get an assistant to help turn the water on for 30 seconds. Then turn it then turn it off. d) Replace the filter cartridge and verify the solution worked.4. If circulation pump is not powering on, try cutting off power at the main

breaker. Turning it on will reset cycle for the circulation pump. After the pump primes itself, the error message should go away.

5. Contact dealer or a service technician if problem continues.

COL
Occurs only in Economy mode and Indicates a cool condition where temps have dropped 20°F (11°C) below current settings for them. System activates the heater and jets pump 1 to bring temp within 15°F (8°C) of set temps.No action required, but during cold weather you may want to increase the amount of filtration cycles.
ICE
This only occurs when spa is in Economy mode and stands for “Ice;” means the system has detected a potential condition for freezing and will cause the system to implement freeze protection to get the spa out of the danger zone.No action is needed. The main pump operates in this condition to circulate warm water throughout the plumbing until the unit is warmed up to 15°F (8°C) of the set temps.
– – –
The water temp has raised above acceptable safety limits and triggered the safety “Watchdog” program of the spa system. Condition can cause injury or damage to spa and its components. The spa deactivates in this situation.DO NOT GET INTO THE WATER. Contact dealer or a service technician.
BLBFlashes in between water temps and “blb”
Indicates that spa needs a new UV bulb.Purchase new UV bulb from dealer and reset countdown timer.
