PayPak Service Diagnostic Codes

[craigrpeters]

I have a 3-4 year old Raypak RP2100 335 heater that has suddenly stopped working. It won't spark properly to ignite the natual gas. It worked fine for the first 2 weeks of this season, then stopped.

The front panel error is "PLT". Also, I can hear that the clicking sound of the ignitor inside has stopped.

There's supposed to be a board inside that has a lights which indicate the exact problem -- service diagnostic codes. Does anyone have a list of these codes and what they mean available?

[I keep the pH above 7.2, its definitely getting gas as I can smell it (and like I said it worked for a couple of weeks), and I've completely cut the power several times to no avail.... I think this is a problem with an internal part since its pretty new -- not a problem with dirt build-up, etc.]

Thanks,
