I have an intex above ground pool. i have the intex pump and the salt water system. the salt water system keeps beeping, shows number 90 and it says low flow. it's a new system and i'm confident i installed it correctly. i can see air in the clear tube on top of the salt water system. i can't seem to clear the air. is this the cause of the beeping/low flow? what can i do? thanks!

Hi

The Intex system has an LED that displays various codes when a problem occurs. After one hour of the code flashing and the system beeping, the unit will turn off and not produce any chlorine.

Check the screen for the code that is being displayed. If the unit has turned off, press either the down or up arrow button below the screen to see the last code displayed.

Refer to the owner's manual to identify the code and the meaning. There are three codes that can display. Code 90 is low or no water flow, code 91 is low salt and code 92 is high salt.

Code 90 means the filter is not on, the hoses are clogged, the filter is clogged or the water is flowing in the wrong direction.
There are several things you may need to check and do:

- Ensure the pool pump is on and running.
- Ensure the plunger valves on the pool (if any) are opened.
- Ensure the filter cartridge, cell and debris screen are clean from debris and dirt.
- Ensure the flow sensor (especially the hinge) is clean. See Owner's Manual. Release all trapped air (if any) in the circulation line hose.
- Check he direction of water inlet and water outlet hose. Reverse the hoses if incorrectly connected.
- Check if the flow sensor is loose or not connected properly. If not, please plug the flow sensor firmly into the flow sensor receptacle.
- If code 90 still appears despite above steps, there might be a flow sensor failure. Please contact Intex Service Center for replacement.

Please get back to us if you have further query else please accept the suggestion.
