Hello... we have this WPRB8050 washer that since an hour ago is not draining the water after rinse cycle. And whenever you press the start button it will make this buzz sound like something is stuck. We bought this set 3 years ago, and if everything is ok, we have this 5 year plan that we bought with it at Lowe's. The serial number is 6H917970G model is WPRB8050D1WW. Please let us know how you can help us. Thanks
