Replacing condenser unit?

I have a Creda Simplicity Condenser Drier T622CW. I have taken the condenser unit out to clean it as instructed and it will not go back in completely and therefore prevents the door closing. It used to be fine but this has now happened several times - usually it goes in eventually for no apparent reason but this time we cannot get it to go in.
