very often the dispenser drawer for the fabric conditioner in my washing machine ends up full of water at the end of a wash. Has anyone else had this happening? It's not that serious, but really irritating. Before each new wash I have to pull out the whole drawer and empty the water that has collected, before filling the fabric softener compartment. I've tried dismantling the whole thing and rinsing etc. in a vague attempt to unblock any blockage but same thing still happens. What is it??
