Washer Shift Actuator
The F7 E1 code signifies that the control board cannot sense the basket speed. This component contains the optical tachometer sensor and the shifting motor; an internal failure of the infrared sensor prevents the board from receiving RPM pulses, triggering the error. Replacing the actuator restores the communication loop between the drive system and the control board.

Drive Belt
If the drive belt has slipped or snapped, the motor will spin, but the pulley and the basket (where the tachometer sensor is focused) will remain stationary. This discrepancy between motor output and basket movement results in the F7 E1 code because the sensor reports zero RPM while power is being applied to the motor.

Main Control Board
In rare instances, the logic circuit on the main control board responsible for interpreting the 5V DC pulse from the tachometer sensor fails. If the actuator and harness are verified as functional, the board's inability to process the incoming speed signal necessitates a full board replacement.
