Oh jees! Sorry for the late reply, turned into quite the drama!
I started scooping it out then tried a lot of kettles and then stirring and having to scoop that out as it wouldnt drain.
Then the whole dishwasher started to corrode before my eyes so I thought best to wash it with Fairy Liquid.
That was a mistake and I couldnt scoop that.
So I decided to rinse and the whole dishwasher filled with foam - which I then bailed out into the sink.
2 more rinses and bails and I think the fairy liquid is gone, the water is drained and about to attempt an actual wash
