The WH01X10310 knob washer is a genuine GE replacement part designed for certain GE washers. However, it's important to note that this part is intended for use with GE washers that utilize a timer control knob. Your GE/Mabe Spacemaker Laundry Combo model WSM2702DAW features a water level pressure switch rather than a timer control knob. Therefore, the WH01X10310 knob washer is not compatible with your model.
