How Sarah Fixed Her Jandy AquaPure Salt System Error with a 20-Minute Virtual Call
Not every pool problem requires an expensive service visit. At PoolTrouble.com, we help pool owners troubleshoot common equipment issues in real time. Recently, Sarah reached out after her Jandy AquaPure salt system kept throwing the dreaded “120/121 Low Current Error.”
The Problem: Salt Cell Not Generating Chlorine
Sarah noticed her pool was getting cloudy, and test strips showed very little chlorine. When she checked her Jandy AquaPure 1400 control panel, she saw alternating error codes 120 and 121. These usually mean the salt cell isn’t producing chlorine, often due to scaling, worn electrodes, or wiring issues.
Sarah worried she’d have to replace the entire system. Instead, she booked a 20-minute virtual troubleshooting call with us.
The Diagnosis: Scaling & Old Flow Sensor
After reviewing pictures Sarah uploaded of her AquaPure cell and controller, plus walking her through a few checks during the call, we pinpointed two likely culprits:
✅ The salt cell plates were heavily scaled with calcium deposits, reducing conductivity.
✅ The flow/temp/salinity sensor was original and beginning to fail, a common issue with older Jandy systems.
The Solution: Cleaning & Smart Replacement
We guided Sarah through the proper way to acid-clean her salt cell (a 4:1 water-to-muriatic acid mix, done safely in a bucket). Within an hour of cleaning, her system’s current levels returned to normal.
For the sensor, we recommended replacing it with Jandy’s updated 3-port sensor kit, which typically runs $150–$200 online. By swapping this herself—or with help from a local handyman—Sarah could avoid a $600+ service visit.
Extra Help: Dialing in Water Balance
Since salt systems are sensitive to chemistry, we also walked Sarah through:
🧪 Correct salinity range (3000–3500 ppm) for Jandy AquaPure
🌡️ How water temperature affects chlorine production
⚖️ Keeping pH in the 7.4–7.6 range to minimize scaling
With this knowledge, she’s now confident her pool will stay clear and balanced.
