Using this door gasket is a breeze. First, make sure your washing machine is turned off and unplugged. Remove the old gasket carefully. Then, place the new gasket in the same position as the old one. Make sure it fits snugly all around. Once it's in place, you can plug in your machine and start using it as normal. As for maintenance, keep the gasket clean by wiping it down after each use. This will prevent the build - up of dirt and mold. Also, avoid using harsh chemicals on the gasket as it can damage the material. If you notice any signs of wear or tear, check the guarantee and contact us for a replacement.
