Door Catch/ Spring for Kenwood KDW12SL3A?

hi , the door on my kenwood 12st3a wont close , iv'e taken the door off and checked the locking mechanism, the spring/catch had fallen out, i cannot figure out where this part gets reattached, also from the manuals there is nothing about the spring/catch. does anyone know of how to reattach or if i bought a replacement locking mechanism part would this contain the spring/catch.
