My towels look as if they have bleach spots all over them. these are costco towels so the quality is there. it has ruined many other towels also. I do not nor have ever used bleach on this washer.

I first noticed after buying some really pretty towels with embro emblem. It looked like they were bleached! I chalked them up to me but then washed another and the same thing happened. I then purchased expensive Costco good quality towels and they all like they've been bleached! There are huge spots all over all the towels now. It only does it when towels are being washed and the towels that this washer ruined are beige in color. The darker ones I have stayed the same color. thanks
