well the issue has "fixed itself" a few weeks ago and then returned again. Now it has "fixed itself" again. pretty annoying as it is unpredictable

please read above........ no this is not related to my issue in any way whatsoever. filter is set 2x a day for 2 hours (min) pump would not raise the temp 12 degrees in 2 hours only and there would be no fizzling sound at the heater once the pump turned off

did you ever resolve this? I have exact same issue that has occurred over a span of a year or so. had the OH errors for a while in early-mid 2014 but then they went away. it would occur randomly every once in a while but not too often. now the error is back. the temperatures have been low lately. I believe it is a stuck relay because it just heats until it reaches 110 or until the pump shuts down, and then you can hear the "sizzle" as per post #11 (heat lamp not on, but power is presumably going to the element because water keeps getting warmer, etc) so if it is the relay like I suspect, is it as simple as moving the contact back down. is there anything I can apply to it to make sure it doesnt get stuck again? &; &
