    Default Inaccurate Salt Reading and other problems with Aqua-Rite

    I had my 12,000 gal pool resurfaced in March. When I turned the Aqua Rite system back on, I had a solid red light for No Flow. I bought a new flow switch which produced the same solid red light. I manually tested both, and they worked. I turned on the water with the switch out and water is gushing out of the hole. I used velcro to keep the flow switch engaged. The power and generating lights both turned on. The salt was reading too low for the system to stay generating. I checked the level manually and there was 3200 salt in the pool. I thought it would balance out once the flow issue was no longer a problem. I checked the salt reading a few days later and it showed 0. I live in FL, so my pool runs all year long. The cell I had was 3.5 years old. It passed the test at the pool store, but from everything I read a bad salt reading is caused by the cell.

    I purchased a new cell. I was able to recalibrate the salt level to 500, while my manual test showed 3000. I have tried multiple times to recalibrate it, but the instant reading isn't showing anything higher. I replaced the mother board in June. I don't know what else to check. Is it possible my new cell is defective?

    I don't have any specific answer for you. The Aqua-Rite units are better than most, apparently, but that's not saying a lot. I've never worked on them myself, so I can't really comment. I have no idea what the list of numbers you supplied are.

    I will offer a few observations.
    • 3.5 years of life is unusually long for an SWCG operating year round.
    • Low salt readings may indicate cell failure.
    • It is certainly possible for a new cell to be defective. But it's also possible to damage electronics (and electrical components) putting them in a bad circuit.
    • I'd recommend you use my Super Search page to look through all the major pool forum sites for Aqua Rite troubleshooting.
    • I'd would have recommended calling Hayward, but at this point I think you've changed so much that they are likely to tell you, "You should have called a pro" . . . just because they will have no idea exactly what you've done. (Consumer self-reports of repair efforts are notoriously considered untrustworthy by customer service agents, regardless of industry.)

    Good luck!

    Upgraded membership and moved thread to the SWCG section. You may need to log out and back in to see everything.

    PS.You can search use Google to search multiple pool sites, using Google's 'advanced search operators" to limit your search to specific sites. This page of mine will create the search links for you. Google knows my site -- and all the others -- much better than those sites internal search functions! And, if you need to post pictures -- of your pool, filter, pump, piping, what-not -- there are instructions on this page

    Please note: the Super Search page does NOT search directly; it only CREATES special Google links, that enable a FOCUSED Google search!

    Which cell are you using (T3, T9, or T15)? If the main panel isnít set correctly with the particular cell being used you can get wonky readings.

    Also, check where the cell and flow switch connect to the panel and make sure the connections are clean.

    Concerning the flow switch, make sure when installed the arrows on it match the water flow direction.

    When I started mine up last spring I got the solid no flow light. I made sure the connections were clean, and after running a little while it started working fine and has been fine since (I thought I might need a new switch).

    I am using a T3 cell. The arrows on the switch are lined up. I will check the connections, but the board is new. When I hold the flow switch and manually engage it the system goes to generating. It seems that the water isn't enough to make the connection engage in the pipe, but with the flow switch out the water comes gushing out. It doesn't see to have a block in the line and the pressure is the same as it's always been.

    I take it before the pool was resurfaced it worked fine? Any changes to the plumbing that might have altered the water flow at the flow sensor (turbulence)?

    Yes, before the resurface everything was fine. We didnít change anything. I thought maybe debris was stuck in the pipe, but the pressure is the same and water gushes out of the pipe when the flow switch is removed.

    I’m stumped.

    You might have better luck doing the searches Ben suggested. I know some on troublefreepool.com are more knowledgeable about SWCGs.

    Thank you for posting the diagnostic and hope Iím not tool late in the game. I labeled the numbers accordingly to help others who are in the need to know. The above numbers indicate that your SWCG is not producing chlorine.

    Just a fyi, you can temporarily bypass the flow switch using an old 2 or 4 wire RJ11 modular telephone cord to test a "No Flow" error condition. Cut the tel cord, splice and twist together the 2 wires in the middle (normally green & red). Disconnect the flow switch from the mainboard and then connect the old tel cord in place. Run the pump, power on the swcg and wait for a minute. If the "No Flow" indicator stays on, then the mainboard is good. You can focus on the flow switch, ensure correct flow direction and inspect the wires for damaged.

    Since you temporarily managed to get rid of the No Flow error, the main board is good. The Aquarite flow switch requires sufficient flow of water to push the mechanical flapper to close the switch. Water gushing out does not mean there is sufficient flow of water to trigger the switch. There might be some restrictions in your plumbing or in case of a VS pump, you may have to bump the speed to satisfy the flow switch.

    JimK response is spot on. Makes sure the cell type match with what was shown on the display. Hereís the link to the Hayward Aquarite Troubleshooting Guidelines for your reference. http://haywarddocs.info/wp-content/u...ting-Guide.pdf

    Are you running the SWCG on a timer? It is possible for the swcg to display odd salinity readings if the cell is continuously powered on without the pump running.
