Using these carbon motor brushes in your Ariston or Technika front - loading washing machine is a breeze. First, make sure your washing machine is unplugged to avoid any electrical hazards. Open the access panel where the old brushes are located. Carefully remove the old brushes by detaching them from the terminals. Then, take your new brushes and attach them to the terminals. Ensure they are properly seated in the brush holder, aligning the locating pins correctly. Once they are in place, close the access panel. You're all set to plug in your washing machine and start using it again. As for maintenance, it's a good idea to check the brushes every few months. Look for signs of excessive wear like short bristles or damage. If you notice any issues, it's best to replace the brushes right away. Remember, keeping these brushes in good condition will help your washing machine run smoothly and efficiently.
