I can't get my White Westinghouse to fill with water. It filled normally, went through its proper cycle, but when it got to rinse, no water came in. Now the barrel does what its supposed to do, but water will not enter the barrel. It even goes through the drain process and sitts there as if filling with water, but no water comes in. When I move the dial to start, it immediately begins agitating. Does anyone know what's wrong? It's not a plumbing problem because it filled properly to start, bt since it drained, I've got no water since
