Indesit WIDL126 flashing and constantly pumping

My new Indesit WIDL126 shows this error code: the spinning led flashes and the lock light flashes faster.
Being highly stupid I forgot to remove the transport holdings so the mashine started jumping when spinning. I noticed one shortcircuit and now the mashine only shows the error code and pumps. I dont know what to do. Make it a try for Warranty? try to open it myself and check that every wire is still plugged?
Does someone know waht this code means? and if I open the top of the mashine do I loose automatic all Warranty? Thanks,
Rodolfo
