Barbarahaps,
I had a similiar problem with a Brand X washer. the problem may be your water pump. if so, it is an easy fix for someone who is mechanically inclined. you first must see where the water is leaking from. when i did this, i securly placed my washer on cinder blocks so that i could see underneath it, and let it fill with a little bit of water, then i could clearly see the water leaking out of the water pump. the key concern here is safety, make sure that the machine fills with only a little bit of water, and then cut the power off to the machine to ensure it doesn't start going through its cycle while up on the blocks, creating a potential hazard. If it is the waterpump, find a washer repair store, tell them the year and model machine you have, and get a water pump on order. the water pump is a pretty straight foward repair--you disconnect power from the machine, turn off and disconnect the water supply, disconnect the drain pipe, and tip over the washer to expose its under side. you disconnect the hoses going to the water pump, remove the attaching bolts, and install the new pump. then you hook everything back up and you should be good to go. hope this helps.
