There comes black stuff out of the washer when i spin. Isit the stasoft?

Fill your machine with hot water (if you only have cold water connected, then add hot water with a bucket) until the machine is filled to the top mark. Add a cup of dishwasher powder and stir it to dissolve. You can also let you machine run a short while, but be carefull that the water is not pumped out. Turn the machine off and let it stand overnight. Then turn it on the next morning and let it wash a complete cycle. You don't have to let the rinse part of the cycle complete. Just turn the machine off when the first water has been pumped out.

What this does: The machine builds of a residue between the drum and outer housing which is not removed in the normal wash cycle, especially if you don't wash with hot water. LG recommends that the machine is cleaned in the above way once "fluff" or black residue is starting to show in clothes after washing.
