When my washing machine is through washing, the water is pumped out to the sewer discharge line which constantly overflows. I have put all kinds of cleaner in it to correct the problem but it hasn't. How can I eliminate this problem?

One of two things. The most likely is a partial clog in the washer drain line. Snake the washer vent from the roof. Put out enough cable to reach the base and about 20 feet more to get out in the main.
The second is the capacity of the trap and standpipe. If you have a older house like I have with a 1 1/2" trap and stand pipe then the newer washer pumps put out much more pressure then they used to and that overloads the system to the point of backing up. You have two options if this is the case.
Redo the trap and standpipe assembly to 2" or install a compression fitting,(see image) on the standpipe and prevent the discharge from backing up. That's what I had to do to my washer and it's been working for years with no backups or problems. 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!
