Using this front - loader washing machine pump is a breeze. First, make sure your washing machine is unplugged to avoid any electrical hazards. Then, locate the old pump and carefully remove it by disconnecting the inlet and outlet hoses and the electrical connector. Next, install the new pump in its place, connecting the hoses and the electrical connector properly. When you're done, plug in the washing machine and start a test cycle. As for maintenance, check the button trap regularly for any debris like buttons or small objects. Clean it out if it's clogged to ensure the pump works efficiently. Also, keep an eye on the electrical connections to make sure they're secure. If you notice any strange noises or reduced water flow, stop using the pump and check for problems. Remember, this pump comes with a guarantee, but following these simple steps will help it last longer and work better.
