IntelliChlor® Diagnostics
Diagnose IntelliChlor cell flow errors, low output, and communication faults.
Common Salt System Problems This Guide Covers
A pool tech should open this document when the IntelliChlor salt cell displays a blinking 'Clean cell' light or alarm, indicating low water conductivity..
What it helps you resolve
- IntelliChlor 'Clean cell' light is blinking
- Salt system stopped generating chlorine due to an alarm
- Suspected faulty temperature sensor on IntelliChlor
- IntelliChlor cell voltage is too high (up to 29V)
- Chlorine generator not working due to low conductivity
When not to use
This document is not for troubleshooting general system errors, installation issues, or routine maintenance procedures unrelated to the 'Clean cell' alarm.
Quick diagnosis
Before replacing any parts, push and hold the 'More' button for at least 3 seconds to enter diagnostic mode and test the temperature sensor. Compare the IntelliChlor's temperature reading with an external thermometer if the 'cold water' light flashes red.

Request ServicePentair Salt System FAQs
What does a blinking 'Clean cell' light on the IntelliChlor indicate?
A blinking 'Clean cell' light signifies an alarm condition due to low water conductivity, which can cause the cell voltage to rise and stop chlorine generation.
Will the 'Clean cell' alarm clear on its own?
No, the 'Clean cell' alarm will persist and prevent chlorine generation until the underlying low conductivity condition is identified and corrected.
What are the most common causes for the 'Clean cell' alarm?
The most common causes include low salt levels, calcified cell plates, low water temperature, air in the cell, or a faulty temperature sensor.
How does this document differ from the IntelliChlor owner's manual?
This document specifically focuses on diagnosing and troubleshooting the 'Clean cell' alarm and related low conductivity issues, whereas an owner's manual covers general operation, installation, and maintenance.
