How the dishwasher works (overview)
To be able to effectively service the dishwasher it is necessary to understand how it has been
designed to operate. The following is an overview of the dishwashers operation:
When checking a program always cancel any previous program by turning the unit on, then holding
down the Start/Stop button for three seconds. Then select the program to be checked.
All components are activated from the control unit, however other actions may have to take place first
before a component is activated (for example the heater will not come on if there is no water in the
machine).
All programs begin with a 25 second drain. The drain pump is partially self-cleaning due to the fact
that the direction of rotation is random. The entire contents of the tub should drain out within that 25
seconds. If not either the filters are not clean, or there is an obstruction in the drain pump, the hose,
the disposal or air break. Note: It is normal to have some water visible beneath the filters.
The unit fills with water via a solenoid operated fill valve controlled by a flow meter or timed fill. The
fill is monitored by a pressure switch which will respond if there is not enough water (for example a
bowl tips over retaining a good volume of water) or if the machine should overfill, by turning on the
drain pump.
The circulation motor/pump forces the water into the two (three) spray arms directly, or via the water
diverter to each spray arm in turn. The motor is capacitor start.
The water diverter has a synchronous motor that drives a disc valve via a gearbox and controls the
water to each spray arm.
The water is heated via a flow through tubular heater suspended between the sump housing and the
Circulation pump. The heater is protected by an auto reset thermal cut-out, and a thermal fuse. 9
How the dishwasher works
The temperature that the heated water reaches is controlled by a thermistor (attached to the inner
door on 3,000 units and in the sump below the door on 5,00 units).
The detergent is dispensed by a solenoid activated dispenser. The first activation dispenses the
detergent, the second activation dispenses the rinse aid. Some units have a rinse aid level indicator
wired to the control unit.
The unit dries by heating the final rinse water to 160 degrees F then dispensing rinse aid into the
water. The injection of the rinse aid gives the water a “sheeting action” off of the dishes and makes it
easier for the water to evaporate.
Drying is further aided by a fan assembly mounted to the inner door. A wax motor opens the vanes
allowing moisture from the tank to pass into the condensation tube. A motor then drives a double sided
fan blade which draws the moisture laden air out of the tank.

Outer Door Removal
Open the dishwasher
door, there are 2
screws at the bottom
of the inner door and 3
down each side. 5 or 6
if the unit is an FI
model
Remove the 2 bottom screws
first
Remove the screws down each
side
Lift the door up, and support the top
of the outer door and ease the
bottom of the door out towards you.
Reach underneath, disconnect the
ground wire from the bracket and lift
up on the bracket slightly to clear
the rim of the tank.

Drain Pump
To remove the drain pump first disconnect the Molex
connector.
Grasp the motor and twist towards
the front (clockwise) to release the motor/impellor from the
housing.
To replace, make sure the seal is in place around the pump
face then firmly push the motor/impellor and seal into the
housing in the vertical position then twist back
counterclockwise until it locks in place

be replaced by
removing the hose

clamp will then be
needed to reconnect
the new assembly. Or
