Having a problem with the water not shutting off. It only happens when the temperature is set to anything that uses some hot water, i.e cool, warm, or hot setting. Cold water filling works as expected. I checked the tube from the level sensor and it seems to be ok. I also disconnected the machine from power during a fill cycle using hot water and the water stops so I think the valves are ok, that is they are not stuck open. Just wondering if anyone may have some other ideas of what the issue could be. Thank you.
