I love my HE front loader washing machine, but last summer I was starting to see spots on a few of our dark shirts. I was very confused. I tried many tricks that others recommended online, but nothing was working. I had a repair man come out to our house to see if something was wrong with my washer. He did many test and determined that the only problem was I was using too much soap. WHAT?!? Too much soap??? I was doing just as the detergent cap recommended for HE washing machines or I was following the lines in the HE washing machine liquid detergent insert.
