    OPERATION WASH SYSTEM Once filling is complete, the dishwasher enters the pre-wash phase. The pre- wash phase conditions the soil with water and detergent to prepare it for removal in the main wash phase. Once water enters the tub, the pump draws the water into the sump through a primary filter at the Sump bottom of the tub to prevent food from circulating...
  • Page 7: Main Wash / Temp Assure

    OPERATION MAIN WASH / TEMP ASSURE After the final reading by the soil sensor, the unit drains before starting to fill for the main wash. The tub fills, with the wash motor starting after the low level pressure switch is activated. The detergent dispenser now opens, introducing detergent into the wash cycle.
  • Page 8: Rinse Phases

    OPERATION RINSE PHASES The first rinse phase following the pre-wash portion of a wash cycle. During this rinse phase, the motor ramps up by 100RPM/second to full speed (2800RPM). Once at full speed, however, the motor will cycle between 1600RPM and 2800 RPM throughout the rest of this rinse phase.
