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? 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
ohms 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.
