INTRODUCTION
The mat erial presented in th is module is inten ded to provide you with a n un dersta nding of the
fundam enta ls of dishwash er an d tra sh m ash er compactor servicing.
Major a ppliances have become more sophisticated, tak ing th em out of the screwdriver an d pliers
category. Their electrical circuits include several different types of automatic controls, switches,
heaters, valves, etc.. Semiconductors, solid-state controls, and other components usually
associated with radio and television electronic circuits are being engineered into automatic
washers, dryers, dishwashers and refrigerators.
The appliance techn ician is emerging into a professiona l statu s of his own. He mu st prepar e
himself now to be able to perform his dut ies today as well as to reta in his pr ofessiona lism in th e
future.
No longer is on-the-job training sufficient to prepare technicians for the complicated procedures
required for t odays sophisticated applian ces. This tr aining can best be obtained th rough organized
classroom study and application. However, much of the knowledge necessary to service todays
appliances can be obtained through study courses. Completion of this and other courses will
provide you with su fficient un dersta nding of applian ces a nd t heir operat ion t o enable you to do
minor service. It will also serve as a va luable stepping stone to more advan ced stu dy and on-th e-
job tra ining t o impr ove your servicing skills.
Informa tion cont ained in th is module is used on WHIRLP OOL appliances.

The directional switch (double pole, double throw)
has only one button and lever and is located in the
console escutcheon a rea. As th e ra m t ra vels appr ox.
3/4 inches down the power screws, the switch con-
tacts change position. When the ram bottoms and
the motor stalls or the circuit is interrupted, themotor will reverse and the ram will start traveling
up the power screws. As the ram comes in contact
with the switch lever, the lever pushes the button
in, the contacts once again change the direction of
electrical flow through the motor windings.

CENTR IFU GAL SWITCH
This par t is located on the dr ive motor. It is used in
getting voltage to the drive motor start and run
windings at the same time. As the drive motor in-
creases in speed, an actuating arm inside the drive
motor drops, causing the button on the centrifugal
switch t o pop out, dropping the volta ge to the sta rtwindings.
Because of different drive motor brands used, it is
necessary when replacing th e drive motor centr ifu-
gal switch, that you use the same brand as your
drive motor.
CHECKING PROCEDURE
Obtain an ohmmeter from your local st ore. We will
be doing RESISTANCE checks. This is the safest
way because the compactor is unplugged from the
power sour ce and avoids th e possibility of receiving
an electrical shock.
Step1 Remove one wire at a time, carefully label-

DRAWER SAFETY SWITCH
This drawer safety switch is located in the back
right side, and prevents the ram from operating if
th e drawer is removed or pu lled out somewha t.
CHECKING PROCEDURE
Obtain an ohmmeter from your local st ore. We willbe doing RESISTANCE checks. This is the safest
way because the compactor is unplugged from the
power sour ce and avoids th e possibility of receiving
an electrical shock.
Step1 Remove one wire at a time, carefully label-
ing each wire according to the term inal ma rking on
the switch. This procedure should assure that the
right wire is reconn ected to the r ight term inal after
checking or r eplacement .
Step2 Set th e ohmm eter scale to the lowest ohms
setting and ZERO the meter.
Step3 With th e butt on (lever) out, t ouch a nd h old
one of the ohmmeter probes to one of the term inals.
Step4 Touch the other ohmmeter probe to the
other terminal.
Step5 The ohmmeter should show an open
circuit with the button (lever) out. If not, the switch
is bad an d needs replacing.
Step6 Press the button (lever) all the way, then
touch an d h old one of th e ohmmet er pr obes to one of
the terminals.
Step7 Touch the other ohmmeter probe to the
other terminal.
Step8 The ohmmeter should show ZERO resis-
tance (continuity) with the button (lever) pressed
all the way. If not, the switch is bad and needs
replacing.
Step9 Reconnect all the wires to the proper
terminals as previously marked.

DR AWER TILT SWITCH (Lev er )
This drawer tilt switch is located in the back left
side, and in-line with th e end of the dr awer t ra ck. If
the drawer is open or tilted during compaction be-
cause of improper loading, the compactor will stop.
To restart the compactor the start switch must be
restarted. When the ram comes to the top, opendrawer and redistribute the trash .

DRAWER TILT SWITCH (P lun ge r)
This par t is located on the front of th e fra me. When
the drawer is closed, the plunger is depressed. The
plunger contacts are open at this time. As the ram
start s i ts downward tra vel and the tra sh causes the
door to pop open somewhat, the contacts close caus-
ing curr ent flow thr ough the reverse star t windingsin th e motor. This causes th e motor t o stall, reverse
and retur n the ram t o the top.
