FUNCTION of SWITCHES, CIRCUIT
BREAKER and INDICATING LIGHTS
This switch serves as the main control for the unit. When pressed into the 'on' position, it
activates the heater controls, the automatic fill and readies the unit for the wash cycle.
When turned off, all power is off. When pushed to drain position and released, the unit will
drain and turn itself off.
This light comes on when the unit is turned on and goes off when the unit is turned off.
Located on top of the unit, behind the latch bracket, this switch serves three functions.
When the door is opened, it will reset the timer to the cycle starting position. When door is
closed, it will start the automatic cycle. If door should be opened during a cycle, it would
act as a safety switch by turning the unit off.
This green light comes on only when the automatic cycle is in progress and goes off when
the cycle is complete.
This switch is used to bypass the timer and operate the wash pump manually. The wash
pump will run as long as this switch is 'on'. Its prime purpose is to extend the wash period
for heavily soiled dishes, but it may be used for deliming.
This is the reset button on a thermostatic overload. Its purpose is to provide a secondary
protection for the wash tank heater element. If the heater element should come on while
the wash tank is empty, this button would pop out, turning off the element and signaling a
problem with the automatic fill.
This light comes on only when the heater reset trips off. Its purpose is to signal that there
is a problem.
