You can clean it a couple different ways. One way is to pull the ice tray which can then be cleaned in the dishwasher. The actual ice maker itself cannot be submerged, it would have to be wiped down with a sponge and soap and water. Another way to clean that i find works best for me is filling the water tank with water mixed with vinger and lime and running the ice maker. This way it runs through all the water pipes and also cleans the ice tubes. Only down fall to this is you would have to run a couple cycles of clean water after to flush out the vinger/lime water mix or else your cubes may have a sour taste.
