Product review (1 stars): This does not fit the Whirlpool WDF510PAYS2
W10195169 now substitutes to W10224428 and the Amazon model number look up said this is the part to order so that is what I ordered.
I take the door apart and take install new dispenser that snaps right into place and there is a gab between the dispenser and the door that would leak. This is not a direct replacement for the Whirlpool WDF510PAYS2.
