Product review (5 stars): leaking washer finally fixed on 3rd try
This is an exact replacement part for my whirlpool duet washer.  The material  is as thick as the original was.  Unfortunately it did not solve my leak.  I also replaced the detergent dispenser hose.  Now it seemed  to be leaking worse than ever. But I could finally see water dripping down inside from above on the right side.  I took the top off and looked inside while the washer was running and I could see water running down the discharge hose.  I ordered a new discharge hose and installed it.  When I looked at the old discharge hose I could see pin holes in it.  The hose was not rubbing against anything inside so I don't know how the hose was damaged inside the washer.  All the parts on the machine were original.

Finally after trying for 3 weeks to get it fixed, the leak was gone.  The problem had been the discharge hose all along.  At this point I think I could take the washer apart in my sleep.
