My washing machine is a Roper top load washer. The problem I am having is that the pump from the cold water drain from under the washing machine. Do I need another pump? The hot water will work. I use the hot water cycle because it drain, but the cold water leaks under the washing machine, I cannot use the cold cycle.

This model is a direct drive with only one pump, the drain pump. If the drain pump leaks, which is a common problem on these models, it will leak no matter what temperature wash is selected! If you a have a leak on cold, it will probably also leak on warm wash. Your problem is your solenoid operated fill valve on the cold side. Only one fill hose comes off of this combination fill valve to your fill plenum at the top back of your tub. So if it leaks on the cold, but not hot, check for a crack in the plastic housing of the valve on the cold half. The valve is located on the inside back of the machine on top right when looking at the front of the machine. They are fairly inexpensive and easy to replace.

Hope this helps
