Joshua. The way to tell is to hold the handle, pull it towards you and if from the very instant you feel no reistance in the handle ( via its spring ) that handle is broken – in other words if it has gone all floppy it is nuked. The only way to fix it is a new handle based on a WDAL8640 in white the white door handle as a kit ( new spring rod handle and striker ) part number Hotpoint drawing on their website is J00301358 but the real part number is C00507932 there is also a pattern part too which is a bit cheaper.
You have to remove the door off the machine, remove all the screws holding the door halves together, then prise the inner door from the outer door in order to fit your new handle. Pointer: BUT before you do anything it is wise to get a marker pen and mark 1 line over the inner door plastic frame at the top AND the glass soley as a reference point for reassembling purposes you`ll see why when you do it. The job can be fiddly if you have not done it before. Take a picture before you dissasemble the door.
