TRAINING MANUAL WM2801H*A
The dispenser works by using various solenoids to apply water to different
compartments. The liquid products are dispensed from a siphon box. As the appropriate
chamber is flooded, the box fills and the water flushes the laundry product into the tub.
It is mixed with water before contacting the laundry to prevent spotting or damaging the
fabric.
Notice that the pre-wash and main wash fill tubes enter the dispenser at an angle. If one
or the other fill valve is opened, the water goes into the appropriate detergent
compartment. However, if they are opened simultaneously, the streams deflect and
dispense the softener. Some water may run through the main and pre-wash
compartments, but since the detergent has already been dispensed in an earlier part of
the cycle, this is of no consequence.
If liquid detergent is added to the pre-wash box, it will run immediately into the tub. This
doesn't affect the operation of the cycle. To use liquid detergent in the main wash, place
the detergent siphon box in the main wash compartment. Otherwise, the main wash liquid
detergent will run into the tub along with the pre-wash detergent, causing oversudsing in
the pre-wash and no cleaning in the main wash.
The siphon boxes are designed to hold a liquid laundry product until the appropriate
time for dispensing into the load. When the box fills with water, it begins to discharge its
contents into the washer fill stream. Once the siphon action has started, it will continue
until the siphon box has emptied itself. Use only regular viscosity bleaches and softeners;
the ultra versions are usually thicker and do not dispense well, if at all.
By the end of any cycle, water will have run through all of the dispenser compartments,
preventing any cross-contamination of subsequent loads.
