AMain Motor and Relay

Most of the dishwashers use 3450 RPM, 120V 60 Hz reversible type motor to drive the pump impellers

These motors utilize an external start relay and have two start or phase windings, a main or run winding and a built-in overload protector

Direction of rotation of the armature or rotor is determined by the start winding selected through the timer switch contacts See Figure 28

FIGURE28

The relay is normally open with its coil connected in series with the main winding of the motor, and its switch con-

tacts connected in series with the motor slart winding (Since the relay is a gravity type device, it must be mounted in an upright poshion ) See Figure 29.

FIGURE29

When voltage is applied to the motor, as during the wash, rinse and drain periods of the dishwashing cycle, fi_e momemary high current to the main winding energizes the relay solenoid The solenoid plunger is lifted, closing the switch contacts The start winding is energized through the timer and relay contacts and the motor armature begins to rotate_ As 1he motor approaches normal running speed, the current in the main winding, and in the solenoid diminishes. When the current through the start relay drops below t0 amps the weight of the plunger

overcomes the weakening magnetic force of the solenoid coil and "drops out," disconnecting the motor start winding
