The macerator and screen are clear. I can reproduce the noise (at low level) by spinning the motor shaft clockwise (from inside the washer cabinet). Noise does not occur if I spin counter clockwise. Washer operates fine otherwise. Any ideas? Mike mharrison attached the following image(s):

Once past that, you are left with the motor itself as the possible cause of noise. Looks like you are on the right track. Great pic BTW.

If you don't have an appropriate screwdriver or bit, find a flat blade that is small enough to find inside the head. It may be rather tight given the age so take it slow.

I see two screw to the right of the motor shaft; one is dark and recessed and looks like is one of a set of four screws. The other is shiny and is proud of the surface. I have the right bits - just need to know which screw! Mike Btw, this window is hard to type in. There is no cursor, and I can only change the last character I typed!
