Two names for one code
F7E1 is unusual because the same code means two different things depending on whether the washer is a top-loader or a front-loader, so you need to know which one you have.
Top-loader vs front-loader meaning
The Cactus Appliance washer code guide splits it. In the top-loader table it is a "Basket speed sensor fault: the optical sensor on the shifter gives no reading." In the front-loader table it becomes a "Motor drive fault: the motor did not run or its speed could not be read." Both versions trace back to the drive system reporting its speed.
The first test
On the top-loader, the source's step is to "Unplug one minute. A repeat is the shifter (actuator) or the belt." On the front-loader, "a repeat needs the motor, its sensor and the motor control tested." Either way, the power-cycle separates a one-off from a drive fault that needs testing.
Non-official repair reference — this page summarizes a technician's guide; it is not a Whirlpool or Maytag service manual, and motor-circuit testing is work for a qualified technician.
