I have taken apart a few washers and 1 dryer. There are insulated copper wires inside that add up. Coming in at the plug entrance and down to the motor. Should have wires going to different dials on the machines. For the dryer, check the trap, may find change or other items that might be valuable. The washer should have a few brass fittings in it maybe the dryer to around dials. The dryer I had was apparently steel. Magnet stuck to the one I had.
