Ok i need help. I like a clean kitchen. Therefore every week i put the hob bits into the dishwasher and wash them as it brings them up perfect. Ive been doing this for some time. Ive just unloaded the dishwasher and one piece is missing. I know i put it in the dishwasher. It went in the top shelf. Dh and i have changed the bit at the bottom, the shelfs everything and its not there! Where else? Please help. This is a rented flat i need that bit.
