Model DUI401 Run 67? Ser 782898RG51 (best guess)has a rust spot at the
juncture of the white base and circular ring under where the spinning
spray arm is. Is this something repairable or retardable or is
failure imminent? Inquiring minds would like to know. We bought
house 6 months ago and think maybe we've bitten off more than we can
chew. Major expenditures aren't on our shopping list but are viable
if required
