Below is a great video on how to clean your Salt Cell

Also, below are great troubleshooting steps from INYOPools website
- “Power” LED not on. Check to make sure either 120VAC or 240VAC input power is connected to the proper screw terminals at the Aqua Rite control. Verify input voltage with a voltmeter. If there is input power, the fuse may have blown. The Aqua Rite is protected by a 20 amp mini ATO fuse located on the circuit board above the cell connector.
- “Generating” LED flashing. The temperature of the pool water is too high or low to operate. You can override this by switching the main switch to SUPER CHLORINATE. The Aqua Rite will run at maximum output for the remainder of the current pump cycle or 24 hours, whichever comes first.
- “No Flow” LED illuminated. The Hayward Aqua Rite has sensed a no flow condition and has stopped generating chlorine. Check that the flow switch is plugged into the connector on the bottom of the control unit and that the wire is not cut or damaged. If there is adequate flow and the LED is still on, check that the arrows on the flow switch (on top of hex) are pointing in the direction of flow. Turn Unit off using toggle switch. Wait for lights to turn off, it will take another minute. Then flip breaker at subpanel, then flip breaker back on to restart system. The Flow Switch requires at least 11gpm so if using a Variable Speed Pump, it needs to be at a faster speed. Pump must be running for their to be “Flow”
- “Check Salt” LED illuminated or flashing. Check salt level in pool/spa. If the salt level is low, add salt according to the chart in the owner’s manual. Before adding large quantities of salt, it is advisable to have your salt level tested by a professional or with test strips.
- “High Salt” LED illuminated. With a test kit, check the salt level in pool/spa. If salt level is too high, lower salt level by draining some of the pool water out of the pool and replace with fresh water. Continue until the salt concentration is at recommended levels.
- “Inspect Cell” LED flashing. Inspect and clean cell according to directions in the owner’s manual. When done, press the “diagnostic” button for 3 seconds to stop the “Inspect Cell” LED flashing.
- “Inspect Cell” LED illuminated. Remove and inspect the cell for scale. If the cell is scaled, follow the directions in the owner’s manual for cell cleaning. If the pool has the proper amount of salt and the “Inspect Cell” LED is still illuminated, the cell may be worn and need replacement.
- “-PCB-” displayed and all 4 red/yellow LED’s illuminated. A possible Printed Circuit Board fault has been detected. Call 1-866-772-2100 for service.
- Causes for little or no chlorine residual. The Hayward Aqua Rite switch is in the “Off” position. The Desired Output % adjustment setting is too low. The stabilizer (cyanuric acid) level is low. The filter pump time is too short (8 hours is average). The salt level is too high or too low (ideal 3200 ppm). The water temperature is warm and this causes a higher demand for chlorine. The water temperature is too low (below 50ºF) and this causes the Aqua Rite to stop generating. There is excessive scaling on the cell. Note: Any one of these problems will cause a little or no chlorine residual.
