IMPORTANT SAFETY INSTRUCTIONS

WARNING: To reduce the risk of fire, electric shock, or injury to persons when using your appliance, follow basic precautions, including the following:

• Read all instructions before using the appliance.
• Do not wash articles that have been previously cleaned in, washed in, soaked in, or spotted with gasoline, dry-cleaning solvents, or other flammable or explosive substances, as they give off vapors that could ignite or explode.
• Do not add gasoline, dry-cleaning solvents, or other flammable or explosive substances to the wash water. These substances give off vapors that could ignite or explode.
• Under certain conditions, hydrogen gas may be produced in a hot-water system that has not been used for 2 weeks or more. HYDROGEN GAS IS EXPLOSIVE. If the hot-water system has not been used for such a period, before using a washing machine, turn on all hot-water faucets and let the water flow from each for several minutes. This will release any accumulated hydrogen gas. As the gas is flammable, do not smoke or use an open flame during this time.
• Do not allow children to play on or in the appliance. Close supervision of children is necessary when the appliance is used near children.
• Before the appliance is removed from service or discarded, remove the door.
• Do not reach into the appliance if the tub or agitator is moving.
• Do not install or store this appliance where it will be exposed to the weather.
• Do not tamper with controls.
• Do not repair or replace any part of the appliance or attempt any servicing unless specifically recommended in the user maintenance instructions or in published user-repair instructions that you understand and have the skills to carry out.
• Do not use replacement parts that have not been recommended by the manufacturer (e.g., parts made at home using a 3D printer).

SERVICE 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 the customer that a time-delay fuse is required.
• Are both hot and cold water faucets open and water supply hoses unobstructed?
• Make sure drain hose is not sealed into drain pipe, and that there is an air gap for ventilation. Ensure drain height is between 39″ (991 mm) and 8′ (2.4 m) above the floor.
• All tests/checks should be made with a VOM (volt-ohm-milliammeter) or DVM (digital-voltmeter) having a sensitivity of 20,000 Ω per VDC or greater.
• Resistance checks must be made with the 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.
• To properly check voltage:
  1. Unplug the appliance or disconnect the power.
  2. Attach voltage measurement probes to the proper connectors.
  3. Plug in the appliance or reconnect the power and verify the voltage reading.
  4. Unplug the appliance or disconnect power after completing voltage measurements.

DIAGNOSTIC LED – MAIN CONTROL (ACU)

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

• LED Flashing – The Control is detecting the correct incoming line voltage, and the processor is functioning.
• LED OFF or ON – Control malfunction. Perform TEST #1: Main Control (ACU), to verify main control functionality.

SERVICE MODE

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.

Activating Service Diagnostic Mode
