Using this pump motor is simple. First, make sure your washing machine is turned off and unplugged. Then, find the old pump motor and remove it carefully. Take your new 4-lug twist-on magnetic pump motor and align it with the proper connections. Twist it on securely until it's firmly in place. Now you can plug your washing machine back in and turn it on. When using, avoid overloading the washing machine as this could put extra strain on the pump motor. For maintenance, check the pump motor regularly for any signs of damage or wear. If you notice anything unusual, like strange noises or leaks, stop using the machine and check the pump motor. Keep the area around the pump motor clean to prevent dust and debris from affecting its performance. And remember, this pump motor comes with a full guarantee, so if you have any problems, you can reach out to us.
