Question about Raypak Rp2100 Pool & Spa Heater Lonox 407k Btu Natural Gas Polymer Header Digital Rp407aenc
Went to heat the spa today and didn't hear heat kick on. The display read CFH - call for heat. I reset everything, and it now displays SPK- spark. Any idea what's wrong and how to fix it?
CFH is a normal function prior to SPK.
Heater says SPK, but you do not hear the spark. Most likely the pilot assembly. Very common with this heater. You need to be comfortable working with gas to change it out but I can guide you through if you are. This is typically not an expensive service call for our company. Please let me know if you would like to proceed, it is a lot to write if not.

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:

you may have a bad pressure switch.if you are getting flow thru the heater and this code is comeing on there are only two reasons.No flow or bad switch.

press the mode button until the display reads "off". Remove the four screws holding the control cover on. Swing panel down so that the back of the board is visible. Press the mode button until "RESfl" appear. Press and hold both "up" and "down" buttons for 5-7 seconds until three dashes appear (---). This resets the fault history and clears any stored faults.

Well, I replaced the pressure switch with no joy. I tried all 5 levels of pressure 1-5 and every wiring combination. Finally, I returned the new $70 pressure switch and took the 2 wires and tied them together (jumped them). Here's the only downside...If you run your pump in backwash, recirc, waste, or any mode that would cause water to bypass the heater it MUST BE OFF. Otherwise, let it ride. It's working great and I hope to go into October weather permitting.
