Before installing, make sure there are rubber gaskets inside the fittings at both ends of the water supply hoses. If there are no water inlet hoses packed with the washer or if the hoses are damaged, Call RCA Service Center. Installing the water supply hoses without rubber gaskets can cause water leakage. When you initially install the washer, be sure to use new hoses. Failing to do so may result in a water leakage or overflow and may damage your property.
