When I first encountered the Heating Error message (the Heavy and Delicate lights on at the same time) the unit would not drain. I discovered that the drain hose was leaking (a possible cause for the error message according to Samsung) and replaced the drain hose. The unit ran well until the final drain cycle and then I received the above error message again. I was able to drain the unit by holding the heavy and delicate buttons for three seconds .
Is there a heating sensor I need to replace and / or some other repair I can make to resolve this?
