Looking for some ideas.. I have a fairly new washing machine, I use good detergents and fabric softeners however my washing sometimes comes out of the machine smelling worse than when it went in. I have cleaned all the cleanable bits, drawer, filter etc, tried the washing machine cleaning sachets, white vinegar on 90 degree was etc and the waste pipe at the back is hooked on so I assume no waste water is getting sucked back into the machine. I am at a total loss as to what is causing it. It's not with every load either. Any ideas?
