Hotpoint Aquarius WML 520 Leaking Dispenser Drawer?

My machine is 4 months old, and has started leaking form the dispenser drawer. I turned the water pressure down, and cleaned the dispenser drawer and it was fine for a week or so, now it's leaking again. It leaks when the water goes into the drawer to wash the fabric conditioner down into the machine. I know this as I have sat and waited for the machine to go onto rinse cycle, and as soon as some water leaked out I quickly opened the drawer and water was spraying into the conditioner section. Any ideas as to what is causing this please? And can it be fixed?
