I can get to recirculation tube by taking off the cabinet with those two screws you mentioned this morning?
And what is the fill flume you're referring to? The lady put an agitator in recently. I asked her if it was leaking before then and she said no. I wonder if the fill tube got knocked at an angle, but I don't know if it's even accessible unless you take the cabinet off, and whether or not it was possible for her to move it slightly. I know how to take the Diverter Valve off, if necessary, and clean that out.
