Product review (1 stars): Need to clean machine in order for it to work!!
I totally agree with all the reviews!  But after having a Whirlpool serviceman come out because of my dark clothes having dirty residue on them, he said I need to use Affresh once a month to clean my machine & all would be well. None of us have ever had to do this to our washing machines before & believe me I have been washing clothes for 50 years! The reason for all of this is because of the low water usage. When the serviceman took my machine apart, the stainless tub sides were covered with a dirty residue and the water at the bottom of the tub was like muddy water! I was sick! My machine is 6 months old! The serviceman had two calls like mine that day. We are saving water, Whirlpool servicemen have jobs and Affresh is making money. Go figure!!
