Hi! I have been racking my brain and reading any article I can find in order to repair my hot tub. I have a Sweetwater Aruba hot tub that throws the OH code and then Watchdog ---. From what I have read I am guessing the temp sensor is bad but where I get confused is when the tub is showing OH the water is actually over heated, ie: not 60 reading 110 but actually 110. Does this mean something else is wrong besides the temp sensor? Any help would be appreciated! Thank you!
