verity sands, February 2011

F6 error on your machine means the machine is detecting a speed reduction.This may be caused by any number of issues,thread caught in the machine or may be an indication that the machine requires servicing.Check the bobbin case area & take up lever linkage for thread caught in the mechanism.If this fails take your machine to an authorised Brother service centre.
