Hello Tony, to answer your question the water level sensing is done directly by the main control board. Before you replace any parts, you should run a Recalibration cycle as per the Technical Datasheet that came with your washer, it is located behind the front cabinet panel up near the top. Next ,in checking the Owner's Guide on water levels :Set the Water Level knob to the Auto Sensing setting and the washer will fill to a level that ensures the load engages the agitator. From this point, the electronic control will sense the load and determine if additional water is needed.Set the Water Level knob to the Deep Water Wash setting and the washer will fill to the maximum water level.Deep Water Wash is not available in the Normal cycle mode.
