After finding two rubber pieces on the floor on the left & right of the dishwasher, after the door was just closed, the door now swings open quickly & loosely and doesn't stay in the down position. Rubber pieces are an inch long, are 1/2 inch wide, are made of hard rubber, have bumps on both sides right in the middle, are hollow (like rubber bands but bigger, thicker & not stretchy). Oddly, both of these pieces appear to be sliced on one end exactly in the same way on both. Washer seems to work fine, isn't leaking, door closes & latches, but there is definitely a problem with the door. Any help appreciated.
