Hi. I'm new here.
I did a search for the parts/service manual for my dishwasher and found it no problem.
My issue though is which part I actually need.
There is no water being pumped up to the mid and upper sprayer arms, so the dishes on the top rack don't get clean. Also there are no error codes on the display. The dishwasher will go through its entire cycle normally. I pulled apart and cleaned the sprayer arms and verified there are no blockages in the tubes leading to the sprayer arms.
What else can I do to troubleshoot the error in order to determine the defective part?
Should I just purchase a complete new sump assembly?
