WARNING
Replace all parts and panels before operating.
Electrical Shock Hazard Disconnect power before servicing.
Failure to do so can result in death or electrical shock.
IMPORTANT
Electrostatic Discharge (ESD) Sensitive Electronics
ESD problems are present everywhere. ESD may damage or weaken the electronic control assembly. The new control assembly may appear to work well after repair is finished, but failure may occur at a later date due to ESD stress.
- ■ Use an anti-static wrist strap. Connect wrist strap to green ground connection point or unpainted metal in the appliance -ORTouch your finger repeatedly to a green ground connection point or unpainted metal in the appliance.
- ■ Before removing the part from its package, touch the anti-static bag to a green ground connection point or unpainted metal in the appliance.
- ■ Avoid touching electronic parts or terminal contacts; handle electronic control assembly by edges only.
- ■ When repackaging failed electronic control assembly in anti-static bag, observe above instructions.
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? Use a time-delay fuse.
- ■ Are both hot and cold water faucets open and water supply hoses unobstructed?
- ■ All tests/checks should be made with a VOM (volt-ohmmilliammeter) or DVM (digital-voltmeter) having a sensitivity of 20,000 Ω per volt DC or greater.
NOTE: Avoid using large diameter probes when checking harness connectors as the probes may damage the connectors upon insertion.
- ■ Check all connections before replacing components. Look for broken or loose wires, failed terminals, or wires not pressed into connectors far enough.
- ■ A potential cause of a control not functioning is corrosion or contamination on connections. Observe connections and check for continuity with an ohmmeter.
- ■ Connectors: Look at top of connector. Check for broken or loose wires. Check for wires not pressed into connector far enough to engage metal barbs.
- ■ Resistance checks must be made with washer unplugged or power disconnected.
DIAGNOSTIC TESTS
There are three diagnostic test modes available: Automatic, Manual, and Console and Indicators. These tests allow the factory or service personnel to test and verify all inputs to the machine/motor control. You may want to allow the automatic test cycle to complete prior to going into specific troubleshooting tests, to verify the functionality of all of the washer subsystems.
ACTIVATION OF AUTOMATIC DIAGNOSTIC TEST MODE
- Be sure the washer is in standby mode (plugged in with all indicators off) or in setting mode (plugged in and power up just before running a cycle).
- Select any one button (except POWER/CANCEL and START/PAUSE) and follow the steps below, using the same button:
- a. Press/hold 3 seconds.
- b. Release for 3 seconds.
- c. Press/hold 3 seconds.
- d. Release
