Integrated dishwasher - refit wooden front please?

We have an integrated dishwasher which has been fine for a year then recently we've started having problems with the wooden front springing off when opening and closing. Now I don't know how to re-fit the wooden front. There are just some plastic sticking out things which go into a hole in the main dishwasher front but I can't make them go or stay in. Any help would be marvelous.
