Hayward Aqua Rite Troubleshooting Guide

hayward aqua rite troubleshooting guide


The Hayward Aqua Rite Salt Chlorine Generator is hands-down the most popular residential salt chlorinator in the pool industry. Just like any other salt chlorine generator, the Aqua Rite may need a quick ‘tune up’ from time to time.

Using information provided by Hayward Pool, we have created the following troubleshooting guide to help pool owners understand the diagnostic codes and quickly restore their Hayward Aqua Rite salt chlorination system.

Check Salt and Inspect Cell LED flashing or ON

Solution: The Check Salt & Inspect Cell LEDs will flash at the same time when the salt level is between 2500-2600 ppm. Chlorine is still being produced when the lights are flashing. When these LEDs are ON, the salt level is 2300 ppm or below. This also means that chlorine production has stopped.

Inspect Cell LED will flash alone when the 500 operational hour timer has expired. To manually reset the Inspect Cell LED, press and hold the Diagnostics button until the LED turns off (about 3-5 seconds).

        1. Verify that the salt level is between 2700 – 3400 ppm. 3200 ppm is the ideal salt level.
        2. Inspect and clean salt cell, if necessary.
        3. Check the cell voltage and amperage in both polarities. To switch polarities, toggle Main Switch from Auto to Off, and back to Auto.


Amp Range per Salt Cell:

          • T-15 Amp Range: 3.1 – 8.0
          • T-9 Amp Range: 2.3 – 6.7
          • T-5 Amp Range: 1.9 – 5.7
          • T-3 Amp Range: 1.3 – 4.5

How to set turbo cell type (ex. T-15)

Solution: Slide the Main Switch to the “Auto” position (directly under Super Chlorinate). To set the Cell Type, toggle the Main Switch from Auto to Super Chlorinate, and back to Auto. Now, push the Diagnostic button until your cell-type appears on the display (“t-xx”).

How to reset the average salt level

Solution: The average salt level needs to be set during start up and reset when the salt cell is replaced. The factory default is 2800 ppm.

To reset the average salt level, turn the unit off and then back to Auto. Wait for the relay to click (between 5 – 10 seconds). Now, press the Diagnostics button 5 times to display the Instant Salt level on the LCD screen. You may need to wait for the number to settle.

Adjusting the chlorine output

Solution: Desired Output % Dial: 1 – 100 sets the level of cell operation as a percentage of the operating time. For example, 75% is operating and generating chlorine 75% of the total pump operating time.

Please note: If the chlorine level does not increase within 24 hours after increasing the output, test your water with a water test kit to determine the current salt, stabilizer, phosphate and nitrate levels.

Keep in mind: Output is scaled back to 20% of the desired output setting at 60° F. Chlorine production stops at 50° F.

High Salt LED ON

Solution: This LED will be on when the cell amperage is above the maximum limit. High Salt LED is also on if the control is set for the wrong Turbo Cell type. The LCD screen will read “HI”.

Verify that the salt level is 2700 – 3400 ppm. We recommend that you check the salt level with a water test kit to ensure accuracy.

Maximum Amps before automatically shutting down:

T-Cell 3: 4.15
T-Cell 5: 6.40
T-Cell 9: 9.50
T-Cell 15: 10.00

If salt level is above the range, we recommend that you partially drain the pool or spa and refill with fresh water to achieve a salt level of 3200 ppm.

Keep in mind: Each inch of water drained from your pool will reduce the salt level by 100 ppm.

No Flow LED is flashing or ON

Solution: If flashing, wait about 60 seconds after starting the pool pump. Then, check for possible turbulence inside the flow T. Please note: the plumbing installation requires 12 inches of straight pipe before the flow switch. There should be no elbow pipe after the flow switch.

If the No Flow LED is ON, check if the flow switch is installed backward. The arrows at the top of the hex nut need to point in the same direction as the water flow. The flow switch requires a minimum flow rate of 11 GPM to consistently stay closed. Check the wire for any damage.

No LEDs or LCD display screen

Solution: Check to see if the breaker and/or time clock are ON. Then, check the input jumpers for the correct position. 220-240 VAC: the jumpers are on 2 and 3. This is the factory default. If 115-125 VAC: jumpers should be on 1 & 2 and 3 & 4.

Please note: For all other power or wiring issues, please refer to the owner’s manual or HaywardPool.com.

Low or High Cell temperature

Solution: The LCD screen will display “COLD” when the water temperature is below 50° F. The screen will show “HOT” when the water temperature is above 140° F. If the water reaches a temperature above 215° F, the salt cell temperature sensor will short and the cell will need to be replaced. Find new replacement salt cells HERE.

Please note: Chlorine production is scaled back 20% of desired output at 60° F and stops at 50° F.

Important Tips about Chlorine Output & Salt Levels!

        1. Please be aware that the Desired Output % dial on the main panel sets the salt cell operation level as a percent of total operating time. For example, if the pump and filter are programmed to operate a total of 8 hours and the Desired Output % is 50%, the salt cell will generate chlorine for about 4 hours. The factory default output level is 50%.
        2. The displayed salt level is calculated from several variables. The displayed salt level can be significantly different from the actual salt level, when measured with a water test kit. The difference may occur as a result of a dirty or aging salt cell. We recommend cleaning the cell and then take an actual meter measurement of the salt level in your pool. If the cell is clean and the measured salt level is correct, then the cell has most-likely began to age. This will result in a lower calculated salt level. Hayward recommends that you never add additional salt in this circumstance.
        3. After following the steps above, but still experiencing a free chlorine level that is not appropriate, try increasing the Desired Output % in a 25% increment. For example, if the output level is currently at 50%, increase it to 75%. This will allow the salt cell to operate for a longer period in order to generate a sufficient amount of chlorine as the salt cell begins to age. Allow 24 hours to re-test the free chlorine. If needed, increase the output in 10% increments.
        4. Super-chlorination mode is an additional option to raise the chlorine level when making adjustments to the desired output level. To enable, just move the main switch to Super Chlorinate.
