Where is the pump screen located

Brian, we can't answer that question without knowing the full model number of your washer. Sears doesn't make their own appliances; they rebrand them from a number of different manufacturers all under the Series 110 label. So we could be looking at a Whirlpool machine, or a Frigidaire or Maytag, and they are all different so the only way we can tell is with the model information.

Otherwise all we can do is give you guesses, like suggesting that it's probably on a pump somewhere. As you can see, that's not going to be much help.
