Why isn't my Sapphire Spa heating?

Owning a Sapphire Spa brings numerous benefits, including relaxation, hydrotherapy, and quality time with loved ones. However, like any advanced piece of equipment, it may occasionally experience technical issues, such as not heating properly or requiring a factory reset. Addressing these issues is crucial for ensuring your spa operates at peak performance, providing you with the best possible experience. In this blog, we will explore the common reasons behind heating issues in Sapphire Spas, as well as the steps you can take to troubleshoot and resolve them. Additionally, we'll discuss when and how to perform a factory reset on your spa; a helpful technique for restoring its default settings and resolving various operational problems. Armed with this knowledge, you'll be better equipped to maintain your spa and enjoy its many benefits without interruption.

Sapphire Spas are designed to provide an exceptional relaxation experience, and maintaining the ideal water temperature is a crucial aspect of that. If you find that your spa is not heating as expected, there are several factors to consider and troubleshoot before concluding that there's a problem with your spa's heating system. In this section, we'll discuss the importance of checking the spa's mode, the SNZE feature, the H.PMP function, and the H.ELE feature, along with troubleshooting tips to help resolve any heating issues.

The modes which can be set on your spa touchpad

Sapphire Spas come with various operating modes that can affect the heating process.  These modes include Normal, Economy, Away, and Week Modes. 

It is essential to ensure that your spa is set to the correct mode for your desired usage.


Normal Mode :

This mode maintains the set temperature constantly, providing optimal heating for everyday use.


Economy Mode :

This energy-saving mode only heats the water during programmed filter cycles, which may result in a lower water temperature outside of these cycles.


Away Mode :

Designed for extended periods of non-use, this mode minimizes heating to conserve energy.


Week Mode :

This mode allows you to set different temperatures for weekdays and weekends, adapting the heating schedule to your specific needs.


Hint: If your spa is not heating, check that it is set to the appropriate mode for your intended usage. To check which mode your spa is in, navigate to the MODE menu item in the settings. If your spa is set to Economy or Away mode, the heating performance may be reduced to save energy. Switching back to Normal mode should restore the spa's heating capabilities.


SNZE Feature

The SNZE (sleep time) feature allows you to set specific times during the day when the spa's heating system will be inactive. This can help save energy but may lead to the spa not heating properly if the sleep timers are set incorrectly. To check and modify the sleep timers, navigate to the SNZE menu item and review the settings for Sleep timer 1 (1.SNZ) and Sleep timer 2 (2.SNZ). If necessary, adjust the days, begin time and end time for each sleep timer or reset them to factory defaults using the R.SET option.

H.PMP Function

The H.PMP function controls the operation mode of the external heat and cool pump connected to your Sapphire Spa. The available modes are Auto (heat or cool), Heat, Cool, and Off (heat pump disabled). If the heat pump is set to Cool or Off, the spa will not heat. To resolve this issue, navigate to the H.PMP menu item and set the heat pump to Auto or Heat mode.

H.ELE Feature

The H.ELE feature determines whether the heat pump and the inbuilt element are combined for heating or if the heat pump operates independently. If the H.ELE feature is set to Off, the spa will only use the heat pump for heating, which may result in slower or less efficient heating. To change this setting, navigate to the H.ELE menu item and set it to On to enable the combined operation of the heat pump and the heater element within your spa control system.

By checking and adjusting these settings, you should be able to identify and resolve most common heating issues with your Sapphire Spa. If the problem persists, it may be necessary to consult a service technician at the local Sapphire Spa store where you purchased your spa or contact Sapphire Spas customer support in Pakenham Victoria on 03 5941 4511 for further assistance during business hours.


How to reset a Sapphire Spa

Sometimes, despite troubleshooting various settings, you might still encounter issues with your Sapphire Spa. In these cases, performing a factory reset can be an effective solution. A factory reset restores your spa controller to its default settings, resolving issues such as your spa not heating, inaccurate temperature displays, or blowers intermitently not working. In this section, we'll discuss when a factory reset might be necessary and describe the reset process for both SV Series Touchpads and smartTOUCH Touchpads.

When is a factory reset necessary?

A factory reset can be a useful tool for resolving a wide range of issues with your spa. Some common reasons for performing a factory reset include:

- Spa not heating, even after adjusting settings

- Inaccurate temperature display

- Blowers or pumps working only for brief periods

- Other unexplained issues with spa performance

Factory reset process for SV Series Touchpads

If your Sapphire Spa is equipped with an SV Series Touchpad, you can follow the factory reset instructions provided by Spanet. Visit the Spanet website for detailed instructions on performing an EEPROM software reset for SV Series Touchpads : https://spanet.com.au/perform-eprm-software-reset/

Factory reset process for smartTOUCH Touchpads

For Sapphire Spas with a smartTOUCH Touchpad, the factory reset process is slightly different. Visit the Spanet website for step-by-step instructions on performing an EEPROM reset for the SVT43 Series Touchpad : https://spanet.com.au/eeprom-reset-svt43-series-touchpad/

Tips and precautions for performing a factory reset

While a factory reset can help resolve various issues with your spa, it's essential to follow the appropriate steps. Follow the reset instructions carefully for your specific touchpad type (SV Series or smartTOUCH). The reset process may vary between different touchpad models.

Reconfigure your spa settings

After performing a factory reset, you'll need to reconfigure your spa settings, such as operating mode, filtration settings, and sleep timers. Make sure to review and adjust these settings as needed to ensure optimal spa performance.

A factory reset can be a powerful tool for resolving a variety of issues with your Sapphire Spa. By understanding when and how to perform a reset, you can help ensure that your spa operates at peak performance, providing a relaxing and enjoyable experience.

If you're unsure about performing a factory reset or continue to experience issues after completing the process, consult a service technician at the local Sapphire Spa store where you purchased your spa or contact Sapphire Spas customer support in Pakenham Victoria on 03 5941 4511 for further assistance during business hours.

Maintaining your Sapphire Spa for optimal performance

In this section, we'll offer tips for maintaining a clean and efficient spa system and encourage readers to consult the user manual and contact your local store or Sapphire Spas support for any assistance.


Routine checks and monitoring

Performing routine checks of your spas features and settings can help you identify and address potential issues before they become significant problems. Some areas to monitor regularly include:

Filtration system : Clean and replace the filter cartridge as needed to ensure efficient water flow and filtration.

Spa settings : Check the operating mode, filtration settings, and sleep timers regularly to ensure they align with your needs and preferences.

Spa cover : Inspect the spa cover for signs of wear and tear, and replace it if necessary to maintain optimal heat retention and energy efficiency.


Maintaining a clean and efficient spa system

In addition to routine checks, it's essential to keep your spa system clean and efficient. Some tips for maintaining a clean and efficient spa system include:

Regularly clean the spa shell, jets and skimmer basket to remove debris and prevent buildup.

You may wish to use a spa vacuum to remove dirt and debris from the bottom of the spa (ask your local spa & pool shop if they can source this product for you).

Drain and refill your spa according to the manufacturer's recommendations, typically every 6-12 months, to maintain optimal water quality.

Use recommended spa chemicals and follow the manufacturer's guidelines for dosage and frequency.
