can anyone help? my washing machine is 2 years old, it has started leaking when spinning and washing but not on filling, i have cleaned the drawer out i used to use powder but now use liquid in the ball in the drum, the machine smells awful, i have cleaned the door rubber which was full of old powder scum etc and have done a 90c wash, the drawer gets all scummy too, should i use anything to keep machine fresh and also why is it leaking, i can hear dripping coming from the back somewhere, many thanks for any help
