The lid reed switch is found under the right hand edge of the top deck after raising the deck up off the metal cabinet. You can check it easily by closing the lid and press start. If machine starts filling & drum rotates then the lid switch is working. Double check by opening the lid & machine will stop then it will restart when you close the lid. Do not cut the wires to the switch as previous poster suggested. If you do the machine will not stop when lid is lifted. Very dangerous on fast spin especially if you have small kids. Also, these two wires carry 230 volts electricity. If you short them out then your control panel will blow and be history. If lid switch is faulty then buy a new one and replace it.
