Some newer top load washing machines built by Whirlpool (also found under the Maytag and Kenmore brand names) use a load sensing switch to control the water level inside the washer. On older washers this part was called a pressure switch. This sensor switch is located in the top console of the washer, and is usually labeled as the water temperature control (A.T.C. control). This switch senses the load inside the washer, and automatically adjusts the water level in the tub to the proper level.
Common symptoms that this part has when it fails are: filling with water at the very end of the cycle and agitating while filling with water. Whirlpool has not released information on how to test this part out, so you will have to narrow down your problem with a process of elimination. Other parts that can cause similar symptoms to a bad load sense switch are a bad timer, water inlet valve, and a clogged or kinked pressure hose (blowing through this is a good way to make sure it is clear).
Here is how to replace the W10248240 Load Sensing Switch
First unplug the washing machine before working on it.
The sensor switch is labeled as the water temperature switch. Remove this knob.
Next, you will need to access the top console. This is done by using a putty knife to depress the two clips on the left & right hand sides. Some models may use two Phillips screws on the back side of the washer to secure the console. The console will then rotate back and out of the way.
Here is the console flipped out of the way
With the console flipped back and out of the way you will now have access to the sensor switch. Remove the pressure hose and the two wire connectors going to the switch. Then to remove the switch from the console you will need to lift up on the tab on the right hand side, and then rotate the switch 1/4 turn counter-clockwise to remove.
Re-install in the new part in the reverse order.
