what is causing my washing machine to leak from underneath?

My husband has decided to do laundry the past couple of days and last night i noticed water coming from underneath. I unplugged the machine and checked the drain hose and the fill hoses and found no problems. I attempted to do a load of laundry myself and as the tub became full i noticed water coming from the bottom of the washer, i imediately drained the washer and unplugged it. I havent noticed the clothes to be too wet after the wash cycle has stopped but the water did smell "old" if that makes any sense. what should i do? My washer is a Maytag Legacy Series model sav205d
