Raypak 2100 just get SPK then LO codes. won't ignite

Raypak RP 2100 was working fine. Propane was low (30%) and the heater wouldn't come on. It would CFH, then SPK over and over but would never ignite. I thought the gas was low, filled the take, it still just sparks over and over but never lights. eventually turns to a LO code.

SOURCE: raypak pool heater piliot light on heat will not turn on

Make sure that gas control knob is set to ON (counterclockwise). Make sure that ON/OFF switch is ON. Check that temperature setting is high enough to call for heat. Make sure pool pump is running and water is flowing to unit.
If not above there is a diagnostic procedure on page 33 of manual at:

SOURCE: When we tried to light the heater the CFH shows,

The CFH is a Call For Heat.
The SPK tells you that it is creating a spark for ignition.
The LO tells me that you are on propane.
The fact that it doesnt light tells me that either the ignitor is not sparking, or that there is no gas, or an incorrect gas supply.
If this unit is installed with flexible gas line, replace this with rigid black pipe or a larger flex line.

I would contact Raypak technical service and they may be able to help you correct the issue over the phone. This is even more likely since the heater is new. I hope this helps.

Raypak 2100 digital display on start up goes through


There may be a buildup of carbon on your pilot or your gas pressure may be low. It is hard to say without more info on the heater, gas line size and meter size. Depending on where you live it could also be something like spider webs in your gas orfaces. These will cause all to fire normally but not be consistant enough to read fire back to the ignition control. A small piece of bent wire into the orfaces will help to clear this up. As it is not a heater related problem it will not show a ready made answer on the display. Hope this helps, let me know.
