May 17, 2010 · Posted May 17, 2010. My kids were using the hot tub and I went to my pool equipment and saw that my Raypak P-R406A heater was throwing the HL2 code. I turned it off and it started working again. About 15 minutes later the code appeared. Turned off the equipment for 10 seconds then turned back on and it worked fine.
