Question about Raypak Rp2100 Pool & Spa Heater Lonox 407k Btu Natural Gas Polymer Header Digital Rp407aenc
I have a Raypak 2100 pool heater. The heater gives me a variety of error codes. Sometimes it comes on for a few minutes and then shuts off with the code HL2. Other times it won't come on and displays PRS. My filter baskets are all clean. When I turn on my filter I can hear water going through the heater with a swich sound. I suspect that this is cause by a low pressure problem or that some sort of valve is stuck close or only paritally open. At times it even sounded like something was banging around inside the heater. Does anyone know if there is an internal valve or some part that could have broken off or be clogging the heater?
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.
