Using this front - loader pump is quite straightforward. First, make sure your washing machine is unplugged. Then, locate the old pump and remove it carefully. Place the new pump in the same position and connect the inlet and outlet pipes according to the diameter specifications (32mm for inlet and 22mm for outlet). Connect the 20mm drain tube at the 90 - degree connection. Attach the pump using the two mounting holes that are 53mm apart. Finally, connect the 6.4mm spade terminals. When using the washing machine, ensure it's running on 240VAC, 50Hz power supply. As for maintenance, check the button trap regularly for any blockages. If you notice a decrease in water flow, it might be time to clean the pump. And remember, since it comes with a full guarantee, if you encounter any issues, you can always rely on our support.
