TIMER for MODEL JV24
DISHWASHERS
GENERAL DESCRIPTION
The timer is a self-contained (frame mounted) timer of the repeating cycle type. It is mounted on the
control panel of Jackson Automatic Dishwashing machines, to control the automatic functions of these
machines. It consists of a clock motor which operates on 60 cycle, AC, 110VAC. In addition to the clock
motor, the timer also contains a driven cam arrangement which operates three micro switches.
PRINCIPLE OF OPERATION
The timer controls various operations of the automatic washers as per wiring diagram for each machine,
however, the timing cycle and the micro switches are the same for each model. The time for ONE COMPLETE
REVOLUTION of the cam shaft is approximately 300 seconds allowing two wash and two rinse operations for
complete revolution of the cam shaft. The micro switch nearest the timer motor is the hold circuit and
uses both the NO and NC contacts. The middle micro switch controls the wash and uses the NO contact.
Toe micro switch farthest away from the timer motor controls the rinse and uses just the NC contact.
SERVICE INSTRUCTIONS
CAUTION: Always remove the power to the machine before working on the control panel
or while servicing the components on the switch panel. All electrical checks
should be mace by qualified personnel.
The: ooeration can be observed after removing the machine’s kick;:are by loosening the two screws
If -. ;$ determined that the timer is.defective, it is recommended the:

DEFECTIVE MOTOR
A defective motor is indicated by the fact that the cams do not rotate or the machine does not perform
the automatic operations or performs a specific part of the cycle continuously, but works okay on manual.
Remember, the timer motor is controlled by the start switch and the hold micro switch, check this complete
circuit before changing motor. The motor is replaced by:
1. Remove motor leads from shorting bar and neutral.
2. Remove the two screws which hold the motor.
3. Replace with a new motor.
NOTE: It may be necessary to remove complete timer to replace motor; if so, follow steps 1 and 2,
previous page.

REPLACEMENT of SWITCHES
in FRONT DOOR
There are five switches installed in the door's upper-righthand corner. These are the Drain, Start,
Rinse/fill, Heater and Manual wash.
Before working on machine, it is important that the power to the machine be turned off at the Circuit
Breaker - trip Breaker to its off position. Remove inside door from machine by removing the eight screws
on the flanged section of the inside door panel. The five switches are all snapped into place in individual
rectangular holes. By using a screw driver, it is possible to pry up the chromed flange on each side away
from switch and remove the switch from flange. Little pressure should be used to prevent damage of switch
and flange.
After the switch has been checked to see if it’s defective, replacement can be made fey placing the new
switch close to the defective switch and moving one wire at a time, transferring them to the same terminals
on the new switch until all wires have been reconnected. If this is not practical, pull the wires loose, one
at a time, tag them and reconnect them acccrding to the electrical diagram.
Put all switches back into place making sure switch protrudes through front door properly (NOTE: Two
click positions on bracket). Replace inner door panel. Power can be reapplied to the unit and dishwasher
run through cycles, checking all operations after replacement.
INTERLOCK SYSTEM
The Interlock System is designed to prevent the machine from operating wr.en the front door is opened cr
not latched prcoerly.
The Interlock System consists of two safety switches, one mounted sc cna: one door latch has to be cicseo
to complete the circuit. The other switch is iocated so that a pin on the macnir.e depresses a safety switch
mounted cn the coor. to complete the circuit. Either of these switches, if net cepressed, will prevent the
macrune from operating. Basically, the doer must be closed and the door latcn locked in order for the machine
to function.
