Yes, It's called a snake. Over time fiber and grease will build up in a washers drain line. I am no fan of putting harsh chemicals in your system especially if you're on a septic system. Having said that, you can snake the washer line out from one of two places.
You can run the snake down the washer stand pipe past the trap nor you can run it down the vent that services 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!
