I used a washing machine cleaner a few days ago (Ecozone washing machine and dishwasher cleaner), but since then, it stinks.
I can't really put my finger on it, it just smells really musty.
What's the best thing I can do to get rid of this, as I can't use it like this.
Quick update - because I do really appreciate all your help...
My Dad managed to get the front panel off (which was at the bottom, so thanks for that) and there was basically a flood of water everywhere.
He cleaned it out, it was full of mud (sons rugby boots no doubt), and hopefully that will be it.
Many thanks for the help and advise. I was panicking a bit.
