Zodiac – Flow switch with connector – R0823800

The Zodiac R0823800 is an original replacement flow switch with connector, designed for use with Zodiac salt chlorination systems. The flow switch is a critical safety and operational component within a salt chlorinator setup: it detects whether water is actively circulating through the system before allowing the chlorinator cell to activate. This prevents the electrolytic cell from running dry, protecting it from heat damage and extending its operational lifespan. Without a functioning flow switch, the chlorinator cannot confirm safe operating conditions and will typically shut down or refuse to produce chlorine.

This unit comes pre-fitted with a connector cable, making it a direct plug-and-play replacement that slots into the existing wiring harness of compatible Zodiac systems without the need for additional wiring work. The assembly is designed to precise OEM specifications, ensuring accurate flow detection and reliable electrical contact. As a genuine Zodiac spare part carrying part number R0823800, it maintains the same performance and safety standards as the original component installed at the factory.

Compatibility and technical context

The R0823800 flow switch with connector is confirmed compatible with the following Zodiac salt chlorinator models: Zodiac eXO iQ, Zodiac eXO iQ LS, Zodiac GenSalt OT, and Zodiac Hydroxinator iQ. These are mid-to-high-range residential salt chlorination units widely used in domestic swimming pools. The flow switch is typically installed inline within the pool plumbing, downstream of the pump, where it can reliably sense water movement. The integrated connector simplifies the replacement process, as the electrical connection is already terminated and ready to mate with the control unit’s existing socket.

Because the flow switch sits in direct contact with pool water and is subject to the chemical environment of a saltwater system, it is manufactured from materials suited to resist corrosion and chlorine exposure. Over time, flow switches can become fouled with calcium deposits or suffer mechanical wear, reducing their sensitivity or causing false readings. Replacing a suspect flow switch with a genuine OEM part like the R0823800 restores reliable operation and avoids nuisance shutdowns or, conversely, undetected dry-running of the cell.

Suitability and buying guidance

This part is intended for owners of Zodiac eXO iQ, eXO iQ LS, GenSalt OT, or Hydroxinator iQ salt chlorinators who are experiencing flow detection faults, persistent low-flow error codes, or visible damage to the existing flow switch assembly. It is a direct OEM replacement and is suitable for standard residential swimming pools where these Zodiac chlorinator models are installed. No modifications to the plumbing or control wiring are required for installation, provided the existing housing and connector socket are in good condition. Always isolate the pool pump and power supply before replacing the flow switch. If in doubt, installation should be carried out by a qualified pool technician.
