The F7 E1 error code indicates a Basket Speed Sensor Fault in the top-load, belt-drive washer (VMW). F7 E1 is displayed when the main control cannot determine the speed of basket—or speed changes too quickly. The first component to check would be the speed sensor circuit in the shifter, which if not functioning, will generate the F7 E1 error code. However, there are several other potential causes that might also prevent the basket from moving (e.g., calibration, friction, or one of the drive system components, among others) that may also generate this error code.
List of what might cause an F7 E1 Error Code VMW calibration Control not sensing the basket movement Mechanical friction between basket and tub Belt is off, or pulley is loose Weak or disconnected motor capacitor, or broken wires to capacitor Harness issue between control & shifter Harness issue between control & motor Shifter malfunction Motor malfunction Main control
and I would look first at the shift actuator part# w10006355 I change a lot for this error
