Using this pump motor is a breeze. First, make sure your washing machine or dishwasher is unplugged. Then, find the old pump motor and remove it carefully. Attach the new motor to the cover using the screws from the rear of the pump. You have two covers to choose from depending on your needs - one with a 24mm inlet and outlet, and the other with a 39mm inlet and 30mm outlet. Connect the 6.4mm spade terminals at the front of the pump in the receptacle. Once everything is connected, plug in your appliance and test it. When it comes to maintenance, keep the motor clean and free from debris. Check the connections regularly to make sure they're tight. If you notice any strange noises or problems, stop using the motor and contact us. Remember, this product is fully guaranteed, so you can use it with peace of mind.
