Troubleshooting
Common issues and their solutions for your PureSpa.
| Problem | Possible Cause | Solution |
|---|---|---|
| Spa not heating / Error Code E90 | Low water flow or dirty filter cartridge. | Clean or replace filter cartridge. Ensure water level is adequate. Disconnect and reconnect power to clear error. |
| Error Code E91 | Low salt level (if applicable) or water not circulating. | Add appropriate spa salt. Ensure filtration is running. Disconnect and reconnect power to clear error. |
| Bubbles are not uniform | Minor variations in air distribution. | This is generally normal and does not affect performance. |
| Spa losing air pressure | Temperature fluctuations or minor leaks. | Add air as needed. Check for small punctures using soapy water. Cold temperatures can naturally reduce air pressure. |
