TOP-LOAD, BELT-DRIVE WASHER (aka VMW) F7 E1 Error Code (Basket Speed Sensor Fault)
Models:
All HE, Hybrid, and Classic VMW models
Serial Numbers:
All serial numbers
Overview
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
Troubleshooting the F7 E1 Error Code
NOTE regarding multiple error codes: If one of the error codes is a Lid Lock code, especially if it's the last code generated, diagnose the other codes first. The lid is locked as a safety feature if there is a malfunction with the drive system and will be the last code generated.

VMW CALIBRATION
Calibration must be performed when any of the following components have been replaced: Main Control, Basket, Drive Assembly, Suspension, Motor, and Capacitor. Not performing, not completing, or interrupting calibration will result in poor wash performance or faults. Calibration should take only 2-4 minutes to perform.
CONTROL NOT SENSING THE BASKET MOVEMENT
A test procedure is available to check the Optical Sensor directly from the control panel.
- Perform the steps to Activate Service Diagnostics. (Refer to product tech sheet.)
- To access Tachometer Verification Mode, turn the Cycle Selector Knob until the Wash & Done LEDs are lit.
- Press the START button to begin tachometer verification mode. Tachometer
