Using this Haier front - load washing machine door hinge is a breeze. First, make sure your washing machine is unplugged and turned off. Then, remove the old hinge carefully. Align the new hinge with the 120mm mounting holes on your machine and secure it in place. When using the washing machine, avoid slamming the door too hard as it may damage the hinge. For maintenance, keep the hinge clean by wiping it regularly with a dry cloth. If you notice any signs of wear or looseness, check the installation and contact us if needed. We've got you covered with our guarantee, so use it worry - free.
