What Is the Jandy AquaPure System?
The Jandy AquaPure is a salt chlorine generator that converts salt into chlorine to sanitize your pool automatically.
Instead of manually adding chlorine, the system:
Produces chlorine continuously
Maintains consistent water chemistry
Reduces maintenance time
But like any piece of equipment, it can run into issues—and that’s where error codes come in.
Why Error Codes Matter
When your AquaPure displays an error code, it’s trying to tell you:
👉 Something isn’t working correctly
👉 Water chemistry or flow may be off
👉 A component could be failing
Ignoring these warnings can lead to:
Low chlorine levels
Algae growth
Equipment damage
Most Common Jandy AquaPure Error Codes
Here are some of the most common issues you may encounter:
1. Low Salt / High Salt Warning
What It Means:
The system detects salt levels outside the ideal range.
How to Fix It:
Test salt levels with a reliable kit
Adjust salt to manufacturer specs
Avoid overcorrecting
2. No Flow / Low Flow Error
What It Means:
The system isn’t detecting proper water flow.
Possible Causes:
Dirty filter
Clogged pump basket
Closed valves
Failing flow sensor
Solution:
Clean filter and baskets
Check valves
Inspect flow switch
3. Cell Error / Check Cell
What It Means:
The salt cell may be dirty, scaled, or failing.
Fix:
Remove and inspect the cell
Clean with a mild acid wash if scaled
Replace if worn out
4. Temperature Sensor Issues
What It Means:
The system is receiving incorrect temperature readings.
Fix:
Inspect sensor connections
Replace faulty sensor if needed
5. General System Fault
What It Means:
A broader issue with the control board or system.
Fix:
Power cycle the system
Check connections
Consult a professional if persistent
Step-by-Step: How to Diagnose Your AquaPure System
Step 1: Read the Error Code
Start with what the system is telling you.
Step 2: Check Water Chemistry
Salt level
Chlorine level
pH balance
Step 3: Inspect Flow
Pump running properly
Filter clean
No obstructions
Step 4: Inspect the Salt Cell
Look for scale buildup
Check for wear
Step 5: Reset the System
Sometimes a simple reset resolves temporary faults.
Common Mistakes Pool Owners Make
❌ Ignoring error codes
❌ Adding too much salt too quickly
❌ Not cleaning the salt cell
❌ Assuming equipment failure too soon
When to Repair vs Replace
Repair If:
It’s a sensor or flow issue
The cell just needs cleaning
The system is relatively new
Replace If:
The salt cell is worn out
Control board is failing
Repairs cost more than replacement
Pro Tips From the Field
✔ Always confirm salt levels independently
✔ Keep your filter clean to maintain flow
✔ Inspect your cell regularly
✔ Address issues early before water quality suffers
Why Proper Diagnosis Saves You Money
Misdiagnosing a salt system can lead to:
Unnecessary part replacements
Wasted chemicals
Ongoing pool issues
A simple fix—like cleaning a cell or correcting salt levels—can save hundreds.
Final Thoughts
The Jandy AquaPure is a powerful system—but like any equipment, it requires proper care and understanding.
When error codes appear:
Don’t ignore them
Diagnose step-by-step
Fix the root issue
Do that, and your pool will stay:
👉 Clean
👉 Clear
👉 Trouble-free
