VMW Operation


VMW Design


Structure Changes

* Cabinet same as direct drive (separate back

panel). Cabinet is not removable

* Hung suspension (very stable platform)

Higher spin speeds

Reduces vibration/walking

* Basket does not float (WP # 14218862)

* No brake

* Gearcase attached to bottom with 4-10 mm bolts

Customer Viewable Codes


There are three codes viewable by the customer

Long Fill (Wash LED ON)

Long Drain (Spin LED ON)

Lid Lock (Lid Lock LED Flashing)

Non Intuitive Control


Note: Non Intuitive Control

helps keep customers from

inadvertently getting into the

test mode

Test Modes

Diagnostic Test Modes

Allow service tech to test and verify all inputs to the

machine control electronics

Do a quick and overall check of the washer before

going to a specific test—Don’t overlook the obvious


Access Service Diagnostics


Activation MUST be done within 6 seconds

Activation of Test Mode


Correct Activation:

00 and all lights flashing

on/off

Note: To Exit Test at any time

Press Power Button. Washer will

automatically revert to normal operation

after 5 minutes of inactivity

Mode of Operation


Test Mode will be identified with the

LEDs and/or the appropriate number in

the display

Fault Codes Display


F#-type of Fault

E#-component system where

fault is located Fault Code Display: displays last 4

codes. Turn CCW 1 turn at a time to

view the most recent to oldest

Press/Hold START key 3

sec. to clear all faults

Note: a fault/error code will be removed from the memory if

it does not reoccur after 10 consecutive wash cycles

Fault Codes


Automatic Test


Automatic Test: Best done at the end of

service or at completion of the installation of the

product to make sure that everything is plugged

in and to verify proper operation

Turn the cycle selector

knob until Spin Light is

on and/or 02 is in the

display

Valve Resistance Test

Resistance values of all valves are between 890-1300 Ohms

This will test the electrical connections and the valves themselves

Shifter Test

Shifter Voltages/Resistance Checks

Shifter Motor Control

AC output 120 VAC Shifter-Switch DC output

Shifter Motor resistance—J 16 pins 1-2 is

2K-3K ohms-Checks the resistance

through the harness and shifter motor

Always ensure plugs connections

are secure
