DIAGNOSTIC GUIDE

Before servicing, check the following:

  • Make sure there is power at the wall outlet.
  • Has a household fuse blown or circuit breaker tripped? Was a regular fuse used? Inform customer that a time-delay fuse is required.
  • Are both hot and cold water faucets open and water supply hoses unobstructed?
  • All tests/checks should be made with a VOM (volt-ohm-milliammeter) or DVM (digital-voltmeter) having a sensitivity of 20,000 Ω per volt DC or greater.
  • Resistance checks must be made with washer unplugged or power disconnected.
  • IMPORTANT: Avoid using large diameter probes when checking harness connectors as the probes may damage the connectors upon insertion.
  • Check all harnesses and connections before replacing components. Look for connectors not fully seated, broken or loose wires and terminals, or wires not pressed into connectors far enough to engage metal barbs.
  • A potential cause of a control not functioning is corrosion or contamination on connections. Use an ohmmeter to check for continuity across suspected connections.

DIAGNOSTIC LED – MAIN CONTROL

A troubleshooting tool has been implemented onto the main control board—a diagnostic LED.

  • LED ON – The Control is detecting correct incoming line voltage and the processor is functioning.
  • LED OFF - Control malfunction. Perform TEST #1: Main Control, page 12, to verify main control functionality.

ACTIVATING THE SERVICE DIAGNOSTIC TEST MODES

  1. Be sure the washer is in standby mode (plugged in with all indicators off).
  2. Perform the following sequence of movement using the cycle selector knob. NOTE: AFTER RESET, sequence “a” through “e” must be completed within 6 seconds.

RESET - Rotate cycle selector knob counterclockwise one or more clicks to clear sequence.

a. Rotate cycle selector knob clockwise one click and wait 1/2 second.

b. Rotate cycle selector knob clockwise one click and wait 1/2 second.

c. Rotate cycle selector knob clockwise one click and wait 1/2 second.

d. Rotate cycle selector knob counterclockwise one click and wait 1/2 second.

e. Rotate cycle selector knob clockwise one click.

Successful activation of Diagnostic Test Modes will be indicated by all status LEDs (except for Lid Locked) flashing ON and OFF in half-second intervals.

NOTE: LED names may vary between makes and models.

SERVICE DIAGNOSTIC TEST MODES

These tests allow factory or service personnel to test and verify all inputs to the main control board. You may want to do a quick and overall checkup of the washer with these tests before going to specific troubleshooting tests.
