Genuine Pentair iChlor Replacement Flow Switch (523100)
This is the 3 Wire Version
* Note: PLEASE CHECK YOUR SWITCH PRIOR TO ORDERING!
Fix your "No Flow" errors with the Genuine Pentair 523100 Flow Switch. Designed specifically for the iChlor Salt Chlorine Generator, this 3-wire sensor ensures your salt cell only produces chlorine when water is safely moving through the system. This prevents the dangerous buildup of chlorine gas and protects your equipment from damage.
Key Features:
- Direct OEM Replacement: Guaranteed fit for Pentair iChlor Salt Chlorine Generators.
- 3-Wire Design: Precision-calibrated for modern iChlor communication protocols to provide accurate flow data to the control board.
- 1/2" Male Pipe Thread (MPT): Standard threading for easy installation into the iChlor cell housing.
- Safety First: Essential for preventing "Dry Fire" conditions, ensuring your salt cell operates only under optimal flow conditions.
Is your iChlor showing a "No Flow" light?
If your pool pump is primed and water is moving through the cell, but the "No Flow" light remains on, the internal sensor has likely failed. Replacing the 523100 switch is a fast, cost-effective way to get your salt system back online without replacing the entire cell.
Technical Specifications:

Easy installation
I haven’t tried it yet, but will this Winter. I did a quick measurement and it looks to be the same size as my salt cell so I’m expecting it to work perfectly. Thx
When the shipping company didn’t perform, PST Pool Supplies did. Thank you for being responsive. Product was exactly what needed.
Part turned out to not work with the NORVS300 control module. However shipping was quick and company was very responsive when I need the CMS Code. Although the part did not work that was my fault, the PST service was great!
