Maytag washer purchased in 2000

My maytag washer gives off a horrible order. It permeates the whole house. It has been going on for quite some time. I e-mailed the company about 2 years ago. I followed the instructions given to fill the tub and put chlorine bleach into the tub and let it go through the normal cycle to no avail. My husband is very upset, as we cannot do any laundry when we are having anyone over as the odor is so offensive. It is a very putrid smell. Right now I put in a load of towels, and am at my computer in the kitchen and the odor is reeking. You may think that I have a small house, and hence the odor permeating through small quarters, but our house if 2700sq.ft. I am 70 years old, so it is not that It am an amateur. I am also college educated and have raised ten children, so I know my way around the laundry room. Please help me! I have had GE washers all my life and have never had this problem. When I moved into a newly built house after raising all my children, I thought I would treat myself and get a Maytag. The clothes come out clean. I have also taken the top of the agitator off, where the softner is placed and have cleaned the tub numerous times. I would appreciate any help I can get, as I am ready to toss the washer out, but being on a fixed income, this is not an option. Thank you for any help you can give me. Ellen Francis
