This genuine Fluidra water flow switch is an OEM replacement part for the Zodiac Z650iQ MD8 pool heat pump. It detects whether sufficient water is circulating through the unit before allowing the compressor to operate, acting as a critical safety and protection device. A faulty or worn flow switch is a common cause of heat pump shutdown and flow-related error codes.<\/p>\n
This flow switch is a direct replacement part for the Fluidra Zodiac Z650iQ MD8 heat pump. The Z650iQ range is a residential full-inverter heat pump series, and the MD8 denotes a specific single-phase model within that lineup. Always verify your unit’s model reference before ordering to ensure correct fitment.<\/p>\n
Using a genuine Fluidra OEM flow switch ensures the switching threshold and electrical ratings exactly match the original design specification. Aftermarket substitutes may trip at incorrect flow rates, leading to nuisance shutdowns or, worse, allowing the compressor to run without adequate water flow \u2014 risking heat exchanger damage. Genuine parts also preserve your warranty and are quality-tested by Fluidra.<\/p>\n
The flow switch is located in the water circuit of the heat pump and must be replaced with the water supply isolated and the unit fully powered down. Correct sealing of all connections is essential to prevent leaks. Installation by a qualified pool technician or heat pump engineer is strongly recommended.<\/p>","protected":false},"excerpt":{"rendered":"
