Zodiac - High Pressure Switch for Z250 Heat Pump - 75336R0008

Zodiac – High Pressure Switch for Z250 Heat Pump

This is the genuine OEM high pressure switch (position 6 in the official Fluidra exploded view) for the Zodiac Z250 pool heat pump (WH000555). It is a critical refrigeration-circuit safety component that monitors pressure levels within the heat pump and shuts down the compressor automatically if pressure exceeds safe operating limits, protecting the unit from serious internal damage. Replacing a faulty switch promptly restores safe, reliable operation of your heat pump.

So funktioniert es

The high pressure switch continuously monitors the refrigerant line pressure inside the Z250 heat pump. When pressure rises above the preset threshold — due to blockages, refrigerant overcharge, or condenser issues — it interrupts the compressor’s electrical circuit to halt operation and prevent further pressure build-up. Common signs of a failing switch include frequent system shutdowns, error codes on the control panel, or the compressor failing to start under normal conditions.

Kompatibilität

This part is designed and sourced specifically for the Zodiac Z250 heat pump (parent SKU WH000555). The Z250 is a Full Inverter pool heat pump suited to small and medium-sized swimming pools, operating with R32 refrigerant. Always cross-reference your heat pump’s model number and exploded-view diagram (position 6) before ordering to confirm fitment.

Installation

Replacement of a high pressure switch involves working within the refrigerant circuit of the heat pump. This work must be carried out by a qualified, F-Gas-certified technician in accordance with applicable regulations. Using a genuine Zodiac part ensures correct pressure trip-point calibration and maintains your unit’s warranty.
