Cell reads low salt. Test salt, clean the cell, check cell type, reset average salt.
The AquaRite reads low salt. Confirm with your own test, add salt if needed, and clean the cell.
On a Hayward AquaRite, flashing Check Salt and Inspect Cell lights mean the cell reads 2,400 to 2,700 ppm (production continues); solid lights mean 2,300 ppm or less and chlorine production is suspended. Test salt independently, clean the cell, verify the programmed cell type, and reset average salt.
Cell reads low salt. Test salt, clean the cell, check cell type, reset average salt.
If salt is below 3,200 ppm, raise it to 3,200 ppm.
Test salt independently.
AQR159d step 1A. Use the salt addition table in the guide for the amount.
The cell must be clean to report accurate salt readings.
Inspect and clean the TurboCell.
Hayward AQR159d: mix 4 parts water to 1 part muriatic acid (acid into water), stand the cell vertically, fill it to the top, and let it sit in 15-minute intervals until the reaction is complete. Pour the solution back into an approved container, rinse the cell thoroughly, and reinstall.
The cell model on the cell label must match the model programmed in the control center.
Verify the programmed cell type.
AQR159d: t-15 is the factory default. If the programmed type does not match the label, change it.
Reset average salt twice; the two instant readings should be within 500 ppm.
Reset average salt twice.
A TurboCell has two polarities. A clean cell should never show more than a 500 ppm difference between them. If it does, Hayward's next step is replacing the cell.
If the two readings differ by more than 500 ppm, replace the cell with the same model.
Replace the TurboCell if readings disagree.
Then reset average salt. Hayward part numbers: T-CELL-15 / T-CELL-9 / T-CELL-3 (GLX-CELL-xx-W versions when under warranty).

Only after cleaning, programming, and salt-reset checks.
When a clean, correctly programmed cell still shows more than 500 ppm between polarities, Hayward says replace the cell.
Flashing: 2,400 to 2,700 ppm, production continues. Solid: 2,300 ppm or less, production suspended (AQR159d).
3,200 ppm.
It is a reminder every 500 operating hours. After inspecting and cleaning, hold the diagnostics button 5 seconds to reset the timer.
