Hello everyone,


The bottom portion of the tub is in good condition with
a small section of rust. I'm thinking that the black coloring is
coming from either the water injector's rubber or the rubber coming in
from water value. Should I also replace the tup top cover? Could it be
something else?

Could very well be something else. At 26 years, it may be ready to go anyway
so don't put a lot of money into it. Replacing the top takes care of the
symptom, but not the cause. You could easily end up spending 50% to 70% of
the cost of a new machine and then have a major problem in a few weeks from
another part completely unassociated with this problem.

Try cleaning it up and see if it comes back quickly. It could be a 26 year
buildup from some other cause that is just staring to be noticed.
