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,

Sounds like the igniter has gone out. My suggestion is to call the company.

The "PLT" error code means pilot failure. The lack of spark may or may not mean an ignitor problem.

I have seen the "PLT" code come up because the main valve in the heater was in the "off" position. No gas = no pilot. Have also seen clogged pilot-burner orifices. The lack of spark may have to do with water flow issues (dirty filter, clogged basket, etc.), or it may be a problem with the electronics of the heater.

All of these (except turning the gas valve on) will require a competent service tech to diagnose.

So, its now 2 years later (the unit is about 5 years old) and I now have mulitple failures on the piece of crap.

According to our pool company:

1) Pilot module is out and needs to be replaced.
2) Wiring is shot, probably due to flame-ups
3) The bottom spreader pan is rusted almost completely and needs to be replaced.

Total tab to fix this $2700 heater -- $1300 bucks.

NEVER EVER buy a RayPak.
