For what it's worth, my very first sugar wash using a 48 hour Turbo got stuck and after a week there was almost no activity so I decided to clear and run it through my Airstill. The wash was really sweet and the actual ABV was only about 10% from 8Kg of sugar!!.
I didn't get a great amount of spirit in the end and what I did get was also slightly sweet but I learned from it so it wasn't a total loss and yours won't be a loss either.
Whatever your outcome you'll have achieved something most people won't even attempt and nothing teaches like experience and practice and we'll pitch in to help as much as we can. 
If you haven't done anything else with your wash and if you did just put 6Kg of sugar in originally you could try dissolving 1.5Kg of sugar in 1Lt of hot water, let it cool to 25oC. While its cooling scoop 2Lt of your present wash out and discard it (to make room for the new sugar and water mix).
When the sugar and water has cooled to 25oC stir it into the wash making sure to raise all the sediment from the bottom to allow all the yeast to get at the added sugar.
Make sure you wash temp stays constant between 25-30oC and you should get some more activity in the next 24-48 hours. Then let it run until the activity is no more than the odd bubble every few minutes. You're probably looking at another 4-5 days anyway then degas and clear.
Hope this works out for you - Good luck!
