Using this Simpson washing machine ratchet is easy. First, make sure your washing machine is unplugged. Then, locate the timer bezel and carefully remove the old ratchet. Install the new ratchet in its place. When you're done, plug the machine back in and test the timer knob. It should turn smoothly. As for maintenance, keep the area around the ratchet clean. Wipe it down occasionally to prevent dust and debris from building up. If you notice the timer knob getting hard to turn again, check the ratchet for signs of wear. And always remember, if you're not sure about any step, it's a good idea to consult a professional.
