water Pump?

[Medster]

Hello, My washer is going on 4 years old. Well yesterday I was doing a load and the machine filled up with water and now im getting an error code LD well I looked it up and it says (long to drain) I saw several others post that they had the same problem and it was the pump. All it does is hummm and wont stop until I unplug it. So many said they had bad pumps that I thought I would get online and order one. Well it shows two different pumps and I have no clue which one and I would kind like to make sure im on the right track. Thanks
