Dead Hotpoint Wdf 740G

Hi all, first post here.

I recently replaced the element on my hotpoint washer dryer (the one for the dryer - at the top). It worked fine for a few times, and then it tripped my electrics.

It is now dead, will not turn on at all, door is stuck locked with a load of clothes in.

I replaced the fuse, flicked my switch on my electric box and it still didnt work

I then opened up the top, and noticed that the brown wire that comes out the top of the dryer element had come apart in the middle - it is little and silver and looks like fuse wire.

I soldered the wire back together and hoped for the best, but it is still dead.

On inspection all appears to be ok other than that, I can not see anything obvious that would have blown.

What should I do now? Is it going to be cheaper to get a new one, or is there something I can do myself without sending it for a costly repair?

And how do I open the door that is locked shut? I watched an espares video, but it is very unhelpful and does not seem to correlate to mine.

thanks in advance,

Jamie
