Outwardly they look alike, the 10510666 impeller is a push on type, and I have experienced 2 failures. anyone have some insight on them?
Hi @debbie451 It may be easier to contact this parts supplier and ask them. Looking through some parts supplier sites e.g. searspartsdirect.com and partselect.com, it doesn’t seem that they are interchangeable but that is only my take on it. In this link for a WPW10510666 it shows that it is used in the model number that you state is from the user manual i.e. WDF520PADW0 whereas in this link for a WPW10510667 it doesn’t and you think that it would if they were interchangeable.
