I really love my washing machine it's only 3 years old and does everything I need and a bit I don't and it's in great working order. Whilst bored the other day I decided to read the instruction book fully and discovered that I should have been running a cleaning wash every 6 months - basically a 95c wash with no washing or detergent/powder. Trying to be good I did this straight away and since running the 'cleaning' wash my machine stinks! I've since done several normal loads of washing and they're fine but afterwards the smell is back. I sniffed and tracked it down to the drum which now smells really fousty and is making the utility room smell as well. Any ideas on how to get rid of the smell??
