manicsoftub mechanic

dont use bromine in vinyl tubs! ruins em. dont overdose on bromine in the water or you can get heat rash,follicilitis excema and certain other skin conditions expecially if you soak at above 104 i prefer chlorine if done properly

water temp sensor! not too expensive from softub parts dealer. another possibility is the potentiometer settings are wrong or not working due to corrosion open the vinyl pack and look for anything burnt corroded etc all softub models and parts are very specific. so get the right part
