Hose Clamp

The hose clamp is used to hold the water hose in place which will prevent the hose from leaking water. Sometimes the clamp may lose its ability to latch on, causing a leaking washer. For the installation, you will need a flat head screw driver to replace the clamp and a drill to access the screws to remove the front of the washer. Be careful if you do not have specific clamp pliers as the clamp could fly off. Once the front of the washer has been removed, take a quick look for water damage or any obvious signs of where the leak is coming from. If it is not obvious, run water to test.
