Before testing any of the components, perform
the following checks:
• Control failure can be the result of corrosion
on connectors. Therefore, disconnecting and
reconnecting wires will be necessary through-
out test procedures.
• All tests/checks should be made with a VOM
or DVM having a sensitivity of 20,000 ohms-
per-volt DC, or greater.
Disconnect power before servicing.
Replace all parts and panels before operating.
Failure to do so can result in death or electrical shock.
DISPENSER LEVEL SWITCH
Refer to page 4-6 for the procedure for servic-
ing the dispenser level switch.
1.
Unplug dishwasher or disconnect power.
2.
Position the empty dispenser tank with the
level switch facing down.
3.
Disconnect one of the wires from the level
switch terminals.
4.
Set the ohmmeter to the R x 1 scale.
5.
Touch the ohmmeter test leads to the
dispenser level switch terminals. The meter
should indicate continuity (0 Ω).
6.
Position the dispenser tank with the level
switch facing up.
7.
Touch the ohmmeter test leads to the
dispenser level switch terminals. The meter
should indicate an open circuit (infinite).
COMPONENT TESTING
Electrical Shock Hazard
• Check all connections before replacing com-
ponents, looking for broken or loose wires,
failed terminals, or wires not pressed into
connectors far enough.
• Resistance checks must be made with power
cord unplugged from outlet, and with wiring
harness or connectors disconnected.
