Howard G for Model Number WDF780SLYB0 I'm pretty sure the pump is bad. Is there any way to take the pump apart and check the impeller? If not, is there a way to check it without ordering a new one? I have changed the door lock, inlet valve. I have watched the dishwasher running and when it is supposed to be washing the dishes, I can see the water leave the bottom and a little water comes out of the blades but they do not spin. I have cleaned all the blades and still have the same problem. Thanks for your help.
Answer Howard, The only way to check the impeller would be to look inside the pump to see if there is any damage to it. This issue does sound like the pump would be the issue. Read More... Answered by AppliancePartsPros.com | Wednesday, June 21, 2017
