There isn't a bad smell in the washing machine but after the cycle has finished my clothes have NO smell. The clothes looked washed but It doesn't smell of detergent or fabric softer.
I though maybe I was too used to the smells and have changed the brand of detergent but still no smell. I have both increased and decreased how much I use and the wash loads are not too big either.
I have done several hot washes with soda crystals and white vinegar to freshen up my machine but nothing seems to work

It's very doubtful that the detergent manufacturers have changed the composition of their products - the perfumes will be constantly maintained.

More likely that your sense of smell has changed. Different brands and still no smell is unlikely to be caused by the machine.

Good Luck..., October 2016
