- Cleaning Kit: Utilize the included PureSpa Maintenance Accessory Kit, which contains a curved brush, mesh skimmer, and scrubber, to keep the spa interior clean.
- Cover Usage: Always use the insulated cover when the spa is not in use to minimize heat loss and keep debris out.

6. Troubleshooting
If you encounter issues with your Intex PureSpa, refer to the following common problems and solutions:
- Spa Not Inflating/Deflating: Ensure the inflation hose is securely connected and the pump is receiving power. Check for any punctures or leaks in the spa body.
- Water Not Heating: Verify the heater function is activated on the control panel and the desired temperature is set. Check if the filter cartridge is clean, as a clogged filter can restrict water flow and heating efficiency. Ensure the power supply is stable.
- Bubbles Not Working: Check if the bubble function is activated. Ensure the air blower intake is not obstructed.
- Cloudy Water: This is often due to improper water chemistry or dirty filter cartridges. Test the water and adjust chemical levels as needed, and clean or replace filters.
- Control Panel Not Responding: Ensure the wireless control panel is charged and properly seated in its dock. If issues persist, try resetting the main power to the unit.
