Bread-Bakers v098.n035.10

Anyone have this happen?

My Hitachi still makes great bread & dough after 4 years.
For the past month, there are gray streaks in the dough and it doesn't
look good.  The gray teflon is wearing off around the flipper now.
Could this be harmful?  I am making French bread (1 c water, 3 c flour,
1 1/2 t salt, 2 t yeast) when this happens.

Regular bread baked in the machine does not seem to have these gray
streaks.
