A fault lid lock will affect washers in different ways. On the older style washers, a defective lid lock usually only impacts draining/spinning the water out, it may still fill up with water. On the new styles, if the lid is not able to lock, than it will not start the cycle at all. If your washer has a control, then there will be a diagnostic test for the lid lock located in the tech sheet. If your washer has a timer, than you should be able to do a continuity test on the lid lock to determine if it is good or bad.
