WM2688H*M Steam Washer
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 does not 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 much
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.
