What does SW Open mean on 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.
Why does my Raypak pool heater only heat half the time?
If your unit doesn’t have this light, then walk over to your filter pump and check the pressure. Maybe your pump turns on just fine but doesn’t heat the way it used to. For some reason, it seems as if it’s only heating half as well, and taking twice as long.
What to do if your Raypak heater doesn’t fire?
If your Raypak heater doesn’t fire at all, first make sure the unit’s time clock is set to the “On” position. A simple lack of power sometimes leads to a non-firing heater, so check the fuse box for a tripped circuit breaker.
How long does it take for a Raypak pool to shut off?
If the sensor does not see/detect a flame or the electrical continuity thru the flame is not sufficient, the circuitry will shut the gas flow off after a pre-determined amount of time. Usually this is in the 5 second range.
