If your Jacuzzi® spa isn’t operating the way it should, the first step is to check the control panel for error codes or messages. Once you have the code or message, the next step is to refer to the owner’s manual and review the installation and operating instructions.
If you are still not satisfied it is working properly, please follow the appropriate troubleshooting instructions.
Important: If you find any damaged supply cords, please contact Spa World™ for a replacement.
If none of your spa components works, (for example, the pump, jets, and lights), you may check the following.
Check for possible errors and reminder messages on the control panel and take the action required. Please refer to the guide above.
If you did not find any error messages or reminders, the next troubleshooting step is to check the circuit breaker. If the breaker switches itself off, the household circuit breaker might have tripped.
If you found the circuit breaker is indeed tripped, please contact Spa World™ Service. to resolve the problem.
There are several possible reasons the pump isn’t operating properly and most of them are easy to fix.
If after activating the jets, there’s no sound detected or you hear a “buzzing” sound, please turn off the spa and contact your authorised Jacuzzi® dealer or qualified service technician to resolve the problem.
If the motor operates but no water flows to the jets, it’s possible that the pump may not be properly primed.
Please follow the priming instructions below.
Important reminder: This method must be used for the jet’s pumps because these pumps are not connected to the main filter system in any way.
If the pump doesn’t operate after performing the priming procedure above, please contact Spa World™ Service to resolve the problem.
As explained above, an airlock happens if there is trapped air in the pump or plumbing. To resolve the airlock, please follow the guide below.
You’ll need:
If the jets aren’t giving the pressure they typically would, you may follow the troubleshooting steps below.
The Jets Pump icon on the home screen of your control panel can tell you whether the Jets Pump is turned on or off. If you see the pump icon, it means that the Jets Pump is ON.
Click the button below to learn how to turn the Jets Pump ON.
Each Jacuzzi® J-400™ Collection spa incorporates a massage selector that allows you to customize the massage and performance by diverting water between various jet systems.
If you are experiencing a weak or uneven flow through the jets, try adjusting the massage selector position and see if you notice a change in water pressure.
Certain jet systems have their own “toggle” on/off air control. Each control introduces air into the water lines that supply specific jet groups. Simply press any air control button to open or press the opposite side of the button to close.
The water must cover all jets but not touch the bottom of the lowest headrest. If the water level is low, please fill it as necessary.
Dirty or clogged filters don’t only affect the quality of the spa water but might lead to other spa issues. If your filter needs cleaning, refer to the step-by-step guide below.
Your spa gives an alert if it detects that the spa water is too hot. If it is, please don’t enter the spa. You may be at risk of scalding and other overheating injuries. To reduce the temperature of the spa, please do the following.
To reduce the temperature of your spa, you can program the heater settings to Economy Mode.
By removing the cover of the spa, you're allowing the heat to escape which cools down the water.
When using the spa in "Econo" mode, the heater will only turn on during preprogrammed times.
Click the button below to learn a step-by-step guide on how to operate the heating modes on a Jacuzzi® J-400™ Collection Spa.
Ensure that the pumps are turned off and not running continuously.
If your spa doesn’t heat up, you can perform the following troubleshooting steps.
The default display of the control panel shows the current spa temperature. If the water temperature is lower than the temperature you desire, you may adjust its temperature.
One key benefit of quality spa covers is it helps with heat retention. The heating process will be faster with the spa cover in place.
If the heater indicator is displayed, but no temperature increase is experienced after a reasonable period of time, please contact Spa World™ Service to resolve the problem.
The circulation pump runs during the primary filtration cycle, together with the CLEARRAY® and ozone unit.
Important reminder: Any time the circulation pump runs outside of a program cycle, e.g. for heating, that run time will be deducted from the next primary filter cycle. For example, the primary filter cycle is set to 8 hours every 24 hours but the circulation pump comes on for 2 hours to heat the water after the cycle has finished. The next primary filter cycle will only be for 6 hours, not 8 hours.
To change or check the programmed primary filtration cycle of your spa, you may use the guide below.
Check the control panel and make sure there are no errors preventing the pump from turning on. If there’s an error message or reminder that requires action, please follow the guide above.
In warm weather, the water temperature in the spa may exceed the set temperature. This condition may occur due to heat transference from the filter/circulation pump and jets pumps. If the water temperature is higher than 35°C (95°F) and 1°C (2°F) above the set temperature, a “Summer Logic” condition occurs that deactivates the filter/circulation pump and CLEARRAY®.
Water priming is the cycle of the water flowing through the circulation pump into the plumbing and back into the spa. This process activates the circulation pump before the automatic heat cycle begins to ensure there is enough water in the heater tube so that the heater element will not be damaged by overheating.
An airlock is a bubble of air trapped in the pump or plumbing. This air bubble prevents the circulation pump from pumping water and causes the spa controller to trip off.
Hot tubs are most often equipped with flow switches, which are helpful safety devices to monitor the flow of water as it circulates throughout the tub. The heater will turn off if the flow of water is interrupted, keeping it in optimal condition and not causing any damage to the surrounding equipment.
Generally, hot tubs are equipped with two types of sensors, ー water temperature sensor and a Hi-limit temperature sensor. Both are used as safety features to prevent your spa from overheating.
A water temperature sensor, as the name implies, is a device that is used to measure the water temperature of the hot tub which displays on the control panel.
The water temperature sensor is typically installed in the filter housing and is connected to the circuit board. In case this device malfunctions, an error message is displayed on the control panel.
Hi-limit sensors monitor the temperature inside heaters and alert the control system if the temperature exceeds safe levels.
If overheating occurs, the Hi-limit temperature sensor sends a signal to your spa’s circuit board and automatically deactivates the heater. Like the water temperature sensor, in the event that this device malfunctions, an error message is displayed on the control panel.
The alerts and messages on the display of your control panel are important. So be sure to pay attention and perform the outlined troubleshooting steps above.
