The same thing happenned to my Indesit WG1185 i.e. lights are on, washing cycle works through but no movement.  Indeed it was the carbon brushes.  I bought new ones from

They gave excellent service and the carbon brushes were easy to install once you get the machine on its side so it takes some rough handling.
Otherwise perfect.
Hope this helps.
