Samsung DW80R7060 dishwasher detergent door will not open or detergent remains

The checks in more detail

If the lid does not open, the detergent stays put, and dishes come out dirty with a pasty residue in the cup. Start by looking at the lid and the cup. Make sure the lid closed and latched when you loaded the detergent, since a lid that is only partly shut may not open properly. Check that nothing, such as a pan handle, a tall dish or a cup on the top rack, blocks the lid from swinging open; the door needs room to move upwards and outwards.

Wipe the cup and the hinge with a damp cloth to remove crusted detergent, which can glue the lid shut; old powder and gel set hard and need a soak in warm water. Use fresh detergent, because damp or old powder cakes. Then the water. The release mechanism relies on water and heat, so run the tap until hot before the cycle and use a normal cycle rather than a short rinse, since a very short cycle may not release the detergent at all.

Check that the filter at the tub floor is clean and that the spray arm over the dispenser area turns, as water from the arm helps dissolve the detergent. A cleaner cycle can dissolve build-up around the lid. If the lid still does not open with a clear path, fresh detergent and a hot water supply, the release mechanism or its wire may have failed, and Samsung service can test it with the model number DW80R7060 and the serial number.
