  “L” WASHER IMPORTANTElectric 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.ã Use an anti-static wrist strap. Connect wrist strap to ground connection point or unpainted metal in the appliance. –OR– Touch your finger repeatedly to ground connection point or unpainted metal in the appliance.ã Before removing the part from its package, touch the anti-static bag to a green ground connection point or unpainted metal in the appliance.ã Avoid touching electronic parts or terminal contact; handle electronic control assembly by edges only.ã When repackaging failed electronic control assembly in anti-static bag, observe above-mentioned precautions. DIAGNOSTIC GUIDE Before testing washer operation, check the following:ã Is the power cord firmly plugged into a live circuit?ã Has a household fuse blown or circuit breaker tripped? Time delay fuse?ã Are both hot and cold water faucets open and water supply hoses unobstructed? Before opening the unit make sure the washer is unplugged from power outlet.ã Check all connections before replacing components. Look for broken or loose wires, failed terminals, or wires not pressed into connections far enough.ã The most common cause for control failure is corrosion on connectors. Therefore, disconnecting and reconnecting wires will be necessary throughout test procedures.ã 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.ã Resistance check must be made with power cord unplugged from outlet, and with wiring harness or connectors disconnected.
