I removed the sump housing and found that there were some pieces of broken glass in the impellers of the distribution pump and drain(discharge) pump. Both pumps were still good, after removing the broken glass, but the area of the discharge hose, housing connection, inside felt rough and had a hole.It could have been caused by a hot drain pump motor or broken glass.Anyway, after reassembly, using new sump housing and transferring all electrical components to housing, did not need the new replacement drain(discharge pump) that i also purchased, I tried out the dishwasher and it went through all of the cycles just fine without a hitch. NO LEAKS Yea!
