I am having the same issue. The fix that I have found is getting a new magnet because the unit is not sensing the water wall bar when it returns to the back position. I have also seen people replace their magnet with strong nyodidium magnets and silicon. I’d rather not do this, but since this is a very common issue on 1-2 year old dish washers I feel a recall should happen. My dishwasher is 2 years old and was installed in a new construction home. I’m very disappointed as my Samsung appliances in my old home were great, which is why I bought the full suite of Samsung appliances for my new home. I will probably be switching to a different brand when I need to replace my appliances as my dishwasher and dryer both have issues.
