Hayward HAXPSA1930 Water Pressure Switch Assembly (Heater Safety Switch)
The Hayward HAXPSA1930 is a genuine OEM water pressure switch assembly used on compatible Hayward H-Series pool heaters. This safety switch verifies that the heater has adequate water flow/pressure before allowing ignition. If flow is too low (dirty filter, closed valve, pump issue, air in the system, etc.), the switch helps prevent heater operation to protect internal components from overheating and damage.
Fits / Compatibility
- Commonly used on Hayward H-Series ED1 / ED2 style heaters
- Also commonly listed for select Hayward H-Series Induced Draft (IDL) heater applications
- Verify your exact heater model and parts diagram to confirm compatibility before ordering (pressure switch assemblies can vary by model/revision).
What It Fixes
- Heater will not fire due to a failed or out-of-range pressure switch
- Intermittent operation where the heater starts/stops from unstable pressure switch contact
- Corroded, leaking, or damaged pressure switch assembly found during service
Key Features
- OEM Hayward replacement assembly for reliable fit and operation
- Helps confirm adequate water flow before heater operation
- Critical safety component that protects the heater from low-flow conditions
Installation Notes
- Turn off power to the heater at the breaker before servicing.
- Relieve system pressure and follow your heater service manual for removal/installation steps.
- If the heater still won’t fire after replacement, confirm proper pump flow, clean filter, open valves, and correct bypass settings.
- Installation and adjustment should be performed by a qualified technician.

Maintenance Tips
- If your heater is tripping on pressure/flow issues, start by cleaning the pump basket and filter, and confirm all suction/return valves are fully open.
- Low flow is often caused by a dirty filter, clogged baskets, air leaks on the suction side, or a partially closed valve.
- Keep water chemistry balanced to reduce scale formation inside the heater and plumbing, which can restrict flow over time.
