Washing machine door will not open?

This sounds like the min bearings have gone, open the door and see if there is any play up and down on the drum. if so its the bearing if not it could be something that has fallen from a pocket and got stuck between the metal clothes drum and the oute drum casing. a take apart job i am afraid for both issues.

SOURCE: How do I change the door boot seal on a Hotpoint Aquarius WMA31N?

Ok - I will answer my own problem seeing as though I have now fitted it!
1. remove door (2 screws)
2. There is a tensioned wire loop holding the front part of the boot seal in position. - prize off the plastic cap at the 11 o'clock position, all will become clear and you will be able to remove the wire loop.
3. Remove top of washing machine (2 allen screws behind caps at the front.
4. Remove soap dispenser draw and any screws holding the front control panel and top of the door.
5. Remove bottom front plinth (just pull it off) underneath are a couple of screws holding the front panel part of the machine, remove these.
6. Remove front of machine giving you access to the steel band which locks the other end of the boot seal in position. Slacken this band right back using a nut-spinner screwdriver. Pull off the old boot and clean the lip ready for fitting of the new boot.
7. Fit new boot seal using a squirt of washing up liquid as lubricant if needed (mine didn't) to reseat the seal.
8. Refit and tension steel band.
9. Re-assemble front panel, ease boot back into front lip position then refit wire loop using a suitable pair of pliers/molegrips to crimp the retaining plastic cap back in situ.
