Hotpoint WMA62 Red Lock LED flashing will not begin wash?

Hi Guys,
I've got a hotpoint WMA62 washing machine. The fault on this machine is that a Red Lock LED begins to flash after approximately 4 seconds. With this being the case I'm unable to start any wash.

I have checked FixYa for answers and a similar question suggests to hold the door handle manually to ensire it is shut after trying this and checking the washing machines associated manual I'm still unable to remove this flashing Red Lock LED and proceed with a wash.

Any help would be much appreciated.
