Had a look at CDSL mediator but cant be sure that I have found the correct part.
What i need is the ratcheting, garden gate type catch thing that hooks on to a peg on the outer wooden door to close it. It clips into a recess on the front of the machine. It could be 1603742 door lock, but alas there is no picture. Could some kind person with the Hotpoint Info, please take a peek for me and confirm.
