What does water SW Open mean on a Raypak pool heater?
The heater will only operate for a short time before it cuts off and displays the message “Water Sw Open.” Even if the water flow in the pool intake and return appear normal, it still may be possible the flow could be restricted enough to not allow the pressure switch to close and therefore stop the heater from firing.
What’s the difference between Raypak and millivolt pool heaters?
The differences between them are significant, and should be taken into account when designing or replacing your heating system. This design has a constant pilot, sitting just below a small generator. This generator uses the heat of the pilot flame to generate small amounts of power (milli-voltage, or thousands of a volt).

How can I tell if my Raypak pool is working?
Push down and rotate the knob on the gas valve 180 degrees counterclockwise so that the “on” designation on the gas valve knob is lined up with the protrusion on top of the gas valve that has a red dot on it. Faint click is a good sign. Tells me the thermostat is working,. but not necessarily calibrated.

What to do if your Raypak pool heater is not working?
If they look good, it might be a bad switch, or for some reason, water is not reaching the header…check any valves near the intake and make sure they are on and your pump is not on low speed. If you have a heater bypass valve, turn that off to ensure full flow to the heater.
How did the millivolt pool heater get its name?
A millivolt pool heater is one that has a ‘standing-pilot’, burning all the time. It also will not have a digital display panel, usually just an on/off switch and a thermostat dial. A millivolt heater gets its name from the 500-600 millivolts that are created by a thermocouple, called the Pilot Generator.
In addition, millivolt ignition is no longer allowed with natural gas in certain areas (such as California) because of concerns about fuel usage when the unit is not firing. Please consult your local authorities to see if they have specific requirements about pool heater ignition systems.
