The dispenser automatically dispenses both the detergent and the rinse agent
at the appropriate times. The dispenser is activated twice during a wash cycle.

The first time, the dispenser is activated, the lever slides up the right-hand path
of the connecting rod. This action moves the cover catch and releases the
detergent cover. When deactivated, the lever resets to rest under the notch in the center of the

connecting rod. When activated for the second time in a cycle, the lever lifts the connecting
rod by the notch, lifting the rinse dispenser plunger and releasing the rinse agent. When

deactivated, the lever returns to its original starting position. The magnetic sensor is connected
to rinse aid warning light at control panel by wires. When the indicator lights up, it should add
more rinse aid.
