They look unscathed, tho' worth looking at more closely, all the way around the casing.
If the 'heat' has come from within the relay body, then to travel down that terminal and melt the joint would have taken 200+ degrees, in which case the plastic case would almost certainly also be scorched or buckled. No signs of this? If not, then there's every chance you have gotten away with this, and it's all originated from a poor or failing solder joint.
In any case, there is no harm at all - now't to lose - in trying a simple resolder first. Imagine how satisfying?!
Soooo, do you have a soldering iron, and multicore solder?
Even if you haven't soldered before, this is a beaut to begin with, literally as easy as it gets. No sensitive electronic components that can be damaged by a couple of seconds too much heat! No titchy pads or - yuck - surface-mounted nasties. Just a great big muckle relay, gagging to be rejoined to the board. 

Hey, thanks. Yes I have access to one. Everything else looks in good nik. Will try sort it. If it takes some time I'l PM you direct the result

Thanks, but you have a whole audience here, hanging on this thread by a, err, thread.

No rush, but we'd love to hear the outcome.

As Danrv says, worth looking at the other relay solder pads with a magnifying glass too, or take high-res pics zoomed in on your screen. Any remotely dodgy-looking ones, 'wet' then with a melt and an extra wee dab of fresh solder.

No harm in 'wetting' if in any doubt. Each pad should take 3-4 seconds. Do not overheat.

Seems to have fixed the machine! At least the main setting I just use and only really use. (65° heat)

There was a lot of clicking to initiate phases of the wash. Maybe Im hearing it as the exterier panel is off at the moment (Attached to the kitchen cupboard door + handle that is laying up against the wall)

Thank you very much people! Saved hundreds

Fab!
So the actual relay pin was still present (couldn't be certain from the pics whether it had been burnt away), and you resoldered it?
Great result

Yes. Simple's. I think once I get the door+cosmetic kitchen cupboard door on the sounds may be less alarming. 

A setting "Rinse" that I don't use - The plastic bit around the part I plug in broke. Still slots in but could come loose. 
Leave out or gorilla glue it in place?

Good job well done.
Reminds me that I need to get a new soap tablet dispenser for my Bosch Hydrosensor dishwasher.
Gorilla glue would fix the broken plastic part if it fits back ok.

Nice job.
This is an electrical plug connector? Do you have a glue gun? A wee blob over where the two meet should secure it, but still be removable again if needed.
Is the plug a good firm fit in any case, so just needs a small added 'just in case'? Would a strip of insulating tape over the two do this? 
I wouldn't use a glue that can get in to the fitting like super glue, 'cos that could cause damage if you need to undo it again.
