Musty smell, but can't tell from where

A lot of machines can suffer from this problem. It is usually down to a bacteria build up between the drum and the tub. The majority of appliances that suffer form this have been used mainly on 40 degree washes and with a biological detergent.
The best way to get rid of this smell is to place two tablespoons of washing soda or soda crystals in the detergent drawer and then run the appliance empty on the 90 degree wash. You may have to repeat this treatment before the smell goes but it will go eventually. Hope you've checked out & cleaned your filter.
You can give me an excellent rating for the help, can't you? Thanks

I have the same problem with a 3 month old ge front loading washer.after 1 month it started off smelling musty..I thought it was my imagination, now at 3 months old our clothes smell so bad I think we might just have to buy new clothes! everytime I wash a load the clothes smell worse and now you can even smell it just walking into our closet 2 floors up. A new washing washing machine should NOT be doing this! so far leaving the door open in between washes has helped a little but I plan on tipping it back and finding the hidden filter today. Isn't it lovely that they don't mention a filter that needs monthly cleaning or it's location in the manuals?!
