Raypak Heater Error Codes

Raypak HL1 and HL2 error codes on spa heaters? 3

I have a Raypak PR335BL cooler. Whenever we heat the spa to 94 ° F, it trips with HL1 and HL2 error messages. The pressure is 9 psi. So far, the technology has changed the range of fans, HL1 and HL2 and bypass valves. Last time, the technician completely bypassed the bypass valve. It will keep ■■■■■■ at 94 or higher, then it will turn on again, go to 95 or 96, then fire and finally it will go to 100F. He earns about $ 900 or more, hates investing more in this unit. We bought this use 1 year ago, but I think the heater is 7 years old. Tech has been on the deck with Raypak for over an hour. Please help me

Yes, water chemistry is good. I checked the water at the store and everything is fine.

Hi NMexicain, Thanks for your reply. The filter is clean. Check gas pressure. We know what error codes mean, but we don't know why they keep appearing. Replace the thermostat later unless someone else has some suggestions. Thank you very much.

I checked the Raypak model number, but I didn't find your number. When your technician talks to Raypak, they should be able to tell you what this error code means. I doubt your technician, he seems to be a replacement. I will try to replace the spa filter first, 90% of all spa problems are due to filters or low flow. Also check the internal pressure of the gas, which can be very low.

RAM error code

You need to disable your heat exchanger. HL1 and HL2 mean that the temperature in the heat exchanger is very high. The accumulation of mascara outside the heat exchanger does not allow good air circulation. Sooner or later the fire on the side of the heater will be extinguished and the man will change something else. Remove the cap and clean everything that keeps your heat exchanger clean and in good condition.
