Salt cell error codes flashing on your control panel can feel alarming, especially when you don’t know what they mean. The good news is that most of these errors trace back to something straightforward — low salt, dirty cell, flow issue, or a DFW hard water problem you can address without panic. This guide covers the most common pentair intellichlor error codes, hayward aquarite error codes, and Jandy AquaPure errors so you know exactly what your system is telling you and what to do about it.
Pentair IntelliChlor Error Codes
Green LED blinking — low salt. The system is reading salt below its target range. Test your salt level independently with a drop test kit or take a sample to a pool store — onboard sensors drift over time. If salt is genuinely low, add pool-grade salt to bring it to 3,200 to 3,400 ppm. DFW rainstorms dilute salt fast, so this is one of the most common salt cell error codes after heavy weather. Our salt chlorine generator guide covers proper salt management in detail.
Red LED — no flow detected. The cell isn’t sensing water moving through it. Check that the pump is running, the filter isn’t clogged, and all valves are open. If flow is fine but the light stays red, the flow sensor itself may need replacement — $50 to $150. Make sure your filter is clean before assuming a sensor problem.
Yellow LED — check cell. Calcium scale from DFW’s hard water is coating the cell plates and reducing chlorine production. Acid-clean the cell with a diluted muriatic acid solution. The Pentair support page has model-specific cleaning instructions. In North Texas, expect to clean cells every 3 to 6 months because of our water hardness. Our cell maintenance guide walks through the cleaning process.
Alternating red and green — high salt. Salt level is above the system’s maximum threshold. Fix: partial drain and refill to dilute. Test independently first to confirm the reading is accurate.
All lights off — no power. Check the breaker, GFCI, and the fuse on the IntelliChlor control board. Power outages from DFW storms knock these offline regularly.
Cell running but no chlorine output. Three likely causes: the cell has reached the end of its lifespan (typically 3 to 5 years in DFW hard water), the control board has failed, or water temperature is below 60°F. Most salt systems shut down chlorine production in cold water — during a DFW winter morning, that’s normal behavior, not a malfunction.
The CDC reminds pool owners that periods without chlorine generation still require manual chlorine supplementation to maintain safe water.
Hayward AquaRite Error Codes
Inspect Cell light. The system is telling you the cell needs attention. Usually means calcium buildup — clean the cell first. If the light returns after cleaning, the cell is nearing end of life and needs replacement. These are among the most common hayward aquarite error codes in DFW because our hard water accelerates scaling.
No Flow light. Same concept as the Pentair — verify the pump is running, filter is clean, and valves are fully open. If everything checks out, the flow switch may need replacement ($40 to $100). Our pump troubleshooting guide can help rule out pump issues first.
High Salt or Low Salt. Test salt independently. Hayward’s onboard sensor is decent but drifts over time. Confirm with a manual test before adding salt or draining water.
Check System. This is a general fault. Power-cycle the unit first — turn it off at the breaker, wait 30 seconds, turn it back on. If it persists, it’s usually a board-level issue that needs professional diagnosis. The Hayward support page has model-specific troubleshooting steps.
Display showing 000. The cell is disconnected or the cable between the cell and control board is damaged. Check the cable connection at both ends. If it’s secure and you still see 000, the cable or cell terminal needs replacement.
Jandy AquaPure Salt Cell Error Codes
Service indicator. Cell needs cleaning or replacement. Same hard water scaling issue as every other salt system in DFW. Clean first, replace if the indicator returns immediately.
Flow error. Insufficient water flow through the cell. Check pump, filter, and valves. Jandy systems are particularly sensitive to flow restrictions from dirty filters.
Salt error. Always test independently before adjusting. Jandy sensors can read off, especially as the cell ages. According to the Pool & Hot Tub Alliance, independent salt testing should be standard practice regardless of what the onboard display reads.
System not producing despite no errors. Three things to check: water temperature below 58°F (system shuts down), output percentage set too low for your pool’s demand, or the cell is simply at end of life and can’t produce effectively anymore even though it’s not throwing a code. Our water chemistry guide covers how to supplement with manual chlorine when the system can’t keep up.

People Also Ask
What does the red light on my Pentair IntelliChlor mean?
Red means no flow detected. Check that the pump is running, filter is clean, and valves are open. If flow is fine, the flow sensor may need replacement.
What does Inspect Cell mean on Hayward AquaRite?
It means the cell needs cleaning or replacement. Acid-clean it first. If the light comes back immediately after cleaning, the cell is at end of life.
How do I reset my salt chlorine generator?
Turn off power at the breaker, wait 30 seconds, and turn it back on. Some models have a dedicated reset button on the control board. Check your owner’s manual for model-specific steps.
Why is my salt cell not producing chlorine?
Common causes: water temperature too cold, cell scaled with calcium, cell at end of life, output percentage set too low, or a control board failure. Clean the cell and check temperature first.
Does DFW hard water cause more salt cell errors?
Yes. Hard water causes calcium scaling on cell plates much faster than soft water areas. DFW salt pool owners should expect to clean cells every 3 to 6 months and budget for shorter cell lifespans of 3 to 5 years. Our salt water pool cost guide covers the long-term numbers.
