My washing mchine has a mildew odour all the time for last month,
its a year old WHY? please
this smell is caused by mold and mildew that has formed on the upper part of the outer drum -- the main cause of this is the suds in the wash tend to rise above the normal water line and never get rinsed away properly. so to get rid of the smell --- run a empty load of hot water ( hot/hot ) and when the cycle starts - add to the water 1/2 cup of white vineger and 1/2 cup of bleach, also add ( using a small container ) some more hot water to the machine to bring the water level up to a higher then normal height,,, let the machine complete the full wash cycle. now if the smell is still kinda there -- repeat the whole cleaning thing one more time,,, this should remove all traces of mold and mildew that has built up and you should notice a huge difference. to keep this from happening again,, try not to use so much detergent in the wash and after you wash your clothes - leave the lid wedged open slightly to let air into the unit so moisture can escape,, this will prevent mold from growing because the machine will dry out fully.
now at least once a month do this cleaning with the vinegar and bleach and you will never have this problem again.
