Fluidra - Flow Switch for Z200 Heat Pump (2-Wire, 67 mm)

Fluidra – Flow Switch for Z200 Heat Pump (2-Wire, 67 mm)

This genuine Fluidra flow switch (SKU V0088000A) is a safety sensor fitted inside the water circuit of the Zodiac Z200 series pool heat pump. It detects whether sufficient water is flowing through the unit before allowing the compressor to operate, protecting the heat pump from dry-running damage. This part replaces the earlier reference WWA01044 and is the current factory-approved version.

Compatibility

This flow switch is compatible with the Fluidra / Zodiac Z200 R410, Z200 R32, and Z200 Defrost heat pumps (models WH000010, WH000011, WH000012, WH000013, WH000307–WH000310, WH000407–WH000410), as well as the PI20, Alpha, and Power heat pump ranges manufactured from approximately 2015 onwards. Always verify your heat pump’s model number — found on the side panel near the electrical connections — before ordering.

Why Genuine Matters

As a critical safety component, fitting a genuine Fluidra flow switch ensures the correct paddle diameter, switching sensitivity, and 2-wire connector type are matched to your unit’s control board. An incorrect or aftermarket flow switch can cause nuisance fault codes, compressor lockouts, or — worse — allow the heat pump to run without adequate water flow. Sourcing direct from Fluidra’s supply chain guarantees full OEM specification.

Installation

The flow switch is located in the water inlet/outlet circuit of the heat pump and is accessible after isolating the water supply and draining the relevant pipework section. Reconnection uses the standard 2-wire cable harness. While a competent DIY pool owner can undertake this replacement, professional installation by a qualified pool or HVAC technician is recommended to ensure correct sealing and fault-free commissioning.
