I just hooked water up to my fridge and the water taste like dirt.How do I clean it or make it stop tasting like dirt and the ice cubes are white?

Did you put a new water filter in the unit yet?

Just let the water run through it for a few days and it should clear up. Does it have a filter? If the filter is not new you may need a new one because filters collect bacteria and become a culture medium with all the collected dirt. In that case the water tastes like dirt because it is flowing through dirt of the worst kind. DrTom4444
