My washing machine drain will overflow when doing laundry. I have already tried to snake it. An electric snake will not go through. But I can get a manual snake to pass. However, the drain still overflows. What can I do?

Did you snake from the washer roof vent? Take your power snake up there and put out enough snake to reach the base and 20 feet more. Flush the line out by cycling the washer. Good luck, Tom

Over two years ago I purchased a new Kenmore washer with a drain overflow problem. The old washer (only 5 years old) drained fine. Our drain pipe was 2 inches. We thought it was a clogged drain, but it wasn't. We had to temporarily have the gray water exit through the window. Yesterday it dawned on me that the old washer drain hose had a hard plastic "U" where it went into the wall drain pipe; the new hose did not. I went to the store and purchased a new hose with a "U" in the end. Evidently, besides helping the hose stay in the drain pipe, the "U" slows down the waterflow. PROBLEM SOLVED!
