I will be happy to help you out. Can I get the model number to your machine?
Thanks for using JustAnswer.com!
Absolutely, let me know the model number later on, I will be around.
Check around the door seal. Is there any lint or mildew build up around the door.
More than likely this is the cause of the streaks. If you keep this area clean, there may be some built up around the outer tub and not visible. What I recommend to anyone with a front load washer is to use a product called AFFRESH. When you run this through the machine on a regular basis, it breaks down and removes the mildew that builds up where you can't see.
I have heard nothing but good things about this product. It also works well with taking away the odors you get with these machines.
If you have anymore questions please feel free to ask. Thanks Again for using JustAnswer.com!
Any Lowes, Sears, Home Depot will have this, not sure about wal-mart or other stores, but am sure about these places having it.
