FUNCTION of SWITCHES, CIRCUIT
BREAKER and INDICATING LIGHTS
Circuit breaker
P/N 0012000 Rated 15 amps, controls power to control circuit only, I.E. timer, relays. solenoid valve,
water-level control and motors. Circuit breaker does not cutoff power in control box at
incoming terminal board and rinse heater or its relay contacts. Power is still applied to them
when the circuit breaker is in "off" position.
Master switch
P/N 0157500 This switch interrupts all power going to the control circuit, this means that all switches on
control panel are inoperable until master switch is turned "on."
Start switch
P/N 0162500 This switch controls the timer motor through two circuits (see electrical diagram) it is a three-
position switch, up position = start, middle position = off, down position = start. To start, flip
switch toggle in either up or down position; indicating light in center of panel will light
verifying automatic cycle has started. After cycle ends and you are ready to start a new
cycle, flip toggle to opposite position.
Cycle light
P/N 0083500 This light comes on only when automatic cycle is in progress and extinguishes when cycle is
complete.
Manual wash switch
P/N 0155500 This switch is used to by-pass the timer and operate the wash pump manually. The wash
pump will run as long as this switch is "on." The prime purpose of this switch is to extend the
wash period for extremely soiled dishes before putting them through the normal automatic
cycle. It may also be used as an emergency back-up should the timer ever fail to operate.
The required wash time is indicated on the control panel (front).
Rinse/fill switch
P/N 0154000 This switch is spring-loaded and must be held in its up position to operate. When switch is
operated, water is allowed to fill machine through the rinse heads. It may be used as an
emergency back-up in case of timer failure for rinsing dishes. The required rinse time is
indicated on the front control panel.
Heat switch
P/N 0157500 This switch completes the heat circuit which is composed of automatic control devices that
turn heaters on and off to maintain required temperatures.
Heat light
P/N 0083500 This indicating light remains lit all the time the heat switch is on.
