Every year it seems like it's something. I just got around to opening the pool for the season try to fire up the heater and it's not starting at all and throwing an E01 code. I hooked up my multimeter, registering 17 or so on the 20k ohm setting (i believe I have this right - I'm no expert!). The manifold, thermister, high limit switch, and automatic gas shut-off are new. Am I looking at a new board? I'd appreciate any help on what to try next.
