WARNING

Electrical Shock Hazard

Disconnect power before servicing and prevent unit from being switched on

accidentally.

Replace all parts and panels before operating.

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

nished, but failure may occur at a later date due to ESD stress.

• Use an anti-static wrist strap. Connect wrist strap to unpainted metal in the

appliance or water tap

– OR –

Touch your nger repeatedly to unpainted metal in the appliance or water tap.

• Before removing the part from its package, touch the anti-static bag to unpainted

metal in the appliance or water tap.

• 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, run diagnostic test rst, then check the following:

• Make sure there is power at the wall outlet.

• Has a household fuse blown or circuit breaker tripped? 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 or DVM having a sensitivity of

20,000 W per volt DC or greater.

• Check all connections before replacing components. Look for broken or loose

wires, failed terminals, or wires not pressed into connections far enough.

• A potential cause of a control not functioning is corrosion 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 power cord unplugged from outlet, and

with wiring harness or connectors disconnected.
