It means high salt level (above 2500 ppm). If E92 is shown do the following:
- Test the salt level with a salt test kit. If a salt test kit is not available you can take a sample of the pool water to your local pool supply store. They can test the water for you.
- You will need to drain approximately 25% of the water if the salt test confirms a high salt reading. Refill with fresh water. If the salt level test is 2500 ppm, then inspect the electrolytic cell for scale build up. Clean it with kitchen grade vinegar as needed. If the above steps do not resolve the error code, contact Intex Service Center for further assistance.
Note: Always turn the system off and disconnect the power cord before cleaning and servicing.
