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. Any idea how to fix or exactly what the high level 2 code means??
Any help would be appreciated.
