Query: Malita 10 cup percolator

Bought first melitta 10 cup, after a short period of time didnot make coffee anymore, just warm off colored water. Bought a second one ,after a few months same thing ,does not perc long enough to make a cup of hot coffee. Very disappointed with this product it was the only one that was just the right size too bad they don't work very well.
