I have a wooden panel on front of dishwasher door, and it keeps falling off. The only thing that has fallen off, besides the actual panel is a grey plastic strip about 21 inches long with another black strip 22-1/2 inches long. One snaps into the other. I am trying to identify the black part, but cannot find it for sure. I think the grey strip is called a retainer channel - EAP343706. Can anyone help me on the black strip? The other question is, where does this part fit - on upper part of panel or on the bottom. I have tried putting old part back on and have tried both up and down and can't seem to get it to fit. Any help would be appreciated.
