the ice maker will make ice if you pour water in it and dumps; and can still get water at the dispenser but it is a slower water flow. But no water is getting to the ice maker. However, when I pulled out the ref. to look behind, there is a really corroded brown crud at the top of the plastic tube going into the frig. What can I do? Is there a filter on this unit?
