The dishwasher won't start if the door isn't closed securely. Push
the door closed until the door latch closes (i.e. until the latch
clicks). If the dishwasher starts, educate the customer on closing
the door securely.
If the dishwasher won't start when the door has been securely
closed, check the door latch with a magnet. Hold the magnet
over the Hall Effect sensor (located just left of the left screw) – if
the dishwasher starts, the sensor didn't sense the door latch
magnet.
Occasionally a door can catch on the door seal and not close
securely. If the door or door seal is misaligned, realign it. If the
door latch is broken, replace it.

Dispenser
The dispenser, located in the middle of the inner door, reliably
dispenses detergent and rinse-aid.

During each wash program, the dispenser operates twice, once
to dispense detergent and again to dispense rinse-aid.

A "latching mechanism" between the coil actuator and rinse-aid
valve prevents rinse aid from being dispensed when the coil is
initially actuated.
After the detergent cover has opened, the
mechanism changes position like a ballpoint pen (when it's
clicked), preventing the detergent cover from moving and
allowing the rinse-aid pump to dispense rinse aid.
Each 160 VDC control pulse dispenses 1 ml of rinse aid. The
total amount of rinse-aid depends on the dispenser setting. A
vent equalizes the pressure in the dispenser so rinse-aid is
dispensed accurately.

The coil (1) moves the detergent
cover actuator (2) and is powered
by 160 VDC pulses from the
control.
When
the
coil
switched on, the actuator moves
to the left.
The actuator is
connected by a plastic link to the
detergent cover release lever (5).
When the actuator turns the
lever, the detergent cover opens.
