Neff washing machine - door open button not working

[Thistle]

Hi. I have an old Neff washing machine, model W4380X1GB/01. The door seal was mouldy so I purchased a new part and (seemingly successfully) fitted it at the weekend. Ran the machine on a cycle and there were no problems so congratulated myself on a job well done.

However when I next came to do a wash, the door open button on the machine would not function. I then took the front back off the machine to try and identify the problem. My, admittedly untrained, assessment is that the problem is linked to a cable which ties into the door interlock mechanism but is now not connected at the other end. This appeared to be the case when I took off the front panel but I now suspect that it originally was connected to the front panel but came loose when I removed it.

I can manually open the door by isolating the power, taking off the lid and pulling on this cable. However this isn't a great long-term solution for obvious reasons.

I have scoured the internet and the troubleshooting page on this site for an answer but can't find out where the other end of this cable should tie into. I also can't find a manual for the machine that gives any details about this cable.

Can anyone shed any light as to how this should operate? Any help would be hugely appreciated.

The photos below show the disconnected end of this cable, the back of the door open button mechanism and the front panel.
