this should help ( compliments of wpl). I would suspect you have bad shifter.
1. Vertical Modular Washer (VMW)
Belt Drive Washer ‐ lock light is
on, and the unit will not run,
start, or spin — Go into diagnostics
and retrieve the codes, and
clear them. This is very important
since most complaints start with
the lid lock on and blinking, or the
unit will not start and spin.
If, when in diagnostics the codes
are F7E1, F7E5, or motor speed
codes, then chances are it is a motor,
capacitor, or shifter related
issue. Once the codes are cleared,
put the washer into a manual diagnostic
test and run the HEAVY AGITATION;
if after 15‐20 Seconds the
motor runs then you can rule out
the motor, capacitor, control, and
most likely the wiring harness connections
(although still check the
BK wire from the shifter to the control).
Remember, the timing wheel
only turns in the transmission during
the spin cycle.
Next, while in Manual diagnostics,
try to get the unit to spin; if the
motor hums for a split second and
then shuts down with the lid lock
blinking; go back into diagnostic
codes and look for shifter or speed
sensor errors. This is proof that the
shifter/sensor assembly is the issue
because the optical sensor is not
reading the motor speed.
Servicers can run the tests above
without pulling a screwdriver out
of the tool box or using the VOM
and you can accurately diagnose
this in a short time.
VMW Washer Showing F7E1
(Basket Speed Sensor Fault) –
Check for (13 volts, direct current
[VDC]) out of control terminal J2. If
13 VDC is missing, no speed sensor.
Check harness between control J2
and J16 to shifter. Check for open
or cut harness at “wire coil”
mounted under the tub. Shorted
harness will take out the control.
Repair short before replacing control
