526345 Trap Door cover fits under silverware basket. Fits 601, 602, 603 and 605 series or any other where your parts looks identical to this one. INSTALLATION TIP- PLEASE READ! if you order this part, when you install it, in order to avoid breaking the retainer clips, put a dab of COOKING OIL (do NOT use petroleum-based lubricant!) on the u-shaped grooves and this will make it much easier to snap the part onto the rack. When you run the dishwasher, the cooking oil will wash off.
