Positive Displacement Pump
The SmartDispenseTM positive displacement pump consists of a continuous flexible tube running from the detergent reservoir to the inner door detergent outlet. The tube runs around the inside edge of the pump housing. A
3 rollers squeezing the sidewall of the tube. As the impeller is driven counterclockwise by the motor, it squeezes out a predetermined amount of detergent for each 1/3 revolution of the impeller.

To remove the pump
1.Remove the door panel. (See Door Panel.)
2.Remove 2 Phillips head screws from the lower right side of the door edge to release the pump bracket.
3.Remove the grommet from the inner door panel and unplug the tube from the reservoir outlet.
4.Disconnect the wires and remove the pump.
The dispenser pump operates on 120 VDC. During each
The electronic control uses two inputs to determine the total amount of detergent dispensed during the main wash cycle:
•Soil Level determined by the turbidity sensor
•Water Hardness as calibrated for the location
A water hardness selection mode permits the calibration of the water hardness for the location at installation. (See Water Hardness Test and Calibration.)
To determine the amount of detergent to dispense during the main wash, the control uses the following formula:
4ml x Number of
+ 25ml + Additional Quantity for Hardness
The additional quantity is a predefined quantity of detergent based on the water hardness level programmed into the control.
