Fill Funnel

The top section of the fill funnel separates from the
main body. The fill funnel body is held in place by a
nut (located on the inside of the dishwasher).
Rotate the nut counter clockwise to remove the
main body. There is an O-ring seal between the fill
funnel and dishwasher tub. Make certain the O-ring
is fully seated when reinstalling.

Heating Element

The heating element nuts are located on the
underside of the washer, near the door. Ample
force is required to remove the nuts.
Removing the dishwasher from installation
may be required.

14

Door Panel

The door panel covers the main control board,
detergent cup, vent, wax motor, louver, and
door-interlock switch. The outer door panel is
held in place by 14 screws (7 Phillips head
screws per side)

NOTE: Ribbon cable(s) connect the keypad
membrane (2-digit display on some models)
to the control circuit board. Due to the ribbon
length, care much be taken when removing
the door panel to ensure that the ribbon
cable(s) are not damaged.

Membrane Keypad

The door panel must be removed to access
the membrane keypad (see Door Panel).
When removing the membrane keypad, peel
the keypad from right to left.
On models with an LED display, the display is
held in place with a plastic clip.

NOTE: When replacing the keypad membrane,
always run the Service Mode to calibrate the
keypad membrane to the control board.

Control Module

The door panel must be removed to access
the control module (see Door Panel). The main
control is considered a “smart” control,
capable of learning the water temperature
and turbidity characteristics of the home.

It is normal if the cycle times vary over a
period of time from the factory default
settings due to temperature and water
quality.
The control module is held in place by two
screws that secures the module to the right
side of the inner door panel.

To enter service mode, ensure door is closed
and press the following keys.

High Temp Wash. – Heat Dry - High Temp
Wash

If followed correctly Dishwasher will enter into
SERVICE MODE

All LED will illuminate indicating that they are
functioning properly

Press Pots& Pans to activate
Water Solenoid Valve

Press Normal to activate Wash
Motor

Press China & Crystal to
activate Detergent Dispenser

Press Speed Cycle to activate
Heater and Wash Motor

Press Sanitize Darin Pump will
run for two min.

Circulation Pump and Motor

The Dishwasher must be removed from its
installation to gain access to the circulation
pump and motor. The circulation pump can
be activated using Test Mode. Refer to

schematic or strip circuit for motor resistance
value.

It is important to remember the motor does
not start immediately when the dishwasher
cycle has started. If the motor hums, but will
not start, make certain the pump impeller is
free from obstruction and the motor shaft can
turn freely.
The terminals on the induction motor are
labelled L1 and N. The motor is thermally
protected (internally) through the L1 side. The
wiring connector is blue to match the wire
leading to the motor. It is designed to go only
one way on the terminals. Make certain the
connector is fully seated when installing.

Heating Element

The heating element can be activated using
Service Mode.
The dual-wattage heating element produces
850 watts during wash, to help heat the
water, and an effective wattage due to
cycling of 541 watts during the dry cycle.
Water inlet temperature must be at least
120’F for proper drying. If the problem is that
the dishes are not drying correctly, don’t
overlook the rinse agent. A rinse agent will
improve the water sheeting action and drying
performance. It is normal for the stainless
steel tub and inner door panel to retain water
droplets even though the dishes are dry.

16

Clean Sensor

The clean sensor measures the amount of
suspended particles in the wash water in the
sump. The control sends the turbidity sensor a
pulse with modulated 5 volt signal for
calibration and usage during operation

Red

White

Blue

Temperature Sensor:

The dishwasher uses a thermocouple to
measure water temperature. The sensor has a
negative temperature coefficient - as the
temperature rises, the sensor resistance
decreases. At room temperature (25 Degrees
Celsius), the temperature sensor will have a
resistance of 11 K and at 60 degrees Celsius,
the temperature sensor resistance will be 2.8
K

Drain Motor

Drainage system consists of the following
components:
Drain motor
Drain hose (one way check valve)

Water Valve and Flood Switch

The water valve is a 120 VAC solenoid valve
that is switched on/off by the control module.
The flood switch acts as a safety switch ONLY
and does not control normal operation of the

water valve. The flood switch opens the L1
side of the water valve circuit.
The switch is normally open. The weight of the
flood switch float holds the switch closed. The
flood switch will not stop the flow of water if
the valve sticks open from a mechanical
failure.
The water valve can be replaced with the
dishwasher installed.
WARNING: Disconnect power to dishwasher
before servicing water valve and flood switch.
The flood switch is held in place by 2 Phillips
head screws.

Water Valve Test

Attempt to activate water valve using Service
Mode. Pump out water as necessary using
Service Mode. If an intermittent failure is
suspected, activate water valve 5 times using
Service Mode. Water valve should stay on for
50 to 71 seconds per activation and should
not turn on and off during the 50 to 71 second
activation time.

If the water valve is not operating properly or
water level is low, check the following:

17

Water valve, flood switch, flood switch float
and stem, transorb, and then main control.
The flood switch should open when the water
level is approximately ¼ in. above the base
(bottom) of the float dome.
Resistance through the water valve solenoid –
900 to 1200
Clogged screen in water valve.

Control Module

The door panel must be removed to access
the control module (see Door Panel). The main
control is considered a “smart” control,
capable of learning the water temperature
and turbidity characteristics of the home.

It is normal if the cycle times vary over a
period of time from the factory default
settings due to temperature and water
quality.

The control module is held in place by two
screws that secures the module to the right
side of the inner door panel.

Detergent/ Rinse Module

At the second activation (3), the lever lifts the
connecting rod by the notch. This action lifts
the door. The door panel must be removed to
access the rinse dispenser plunger and
release the rinse detergent/rinse module (see
Door Panel) agent. When deactivated, the
lever returns to its original starting position.
The detergent rinse module is held in place by
6 Phillips head screws and 2 brackets.

Detergent/ Rinse Module

The detergent/rinse module automatically
dispenses both the detergent and the rinse
agent at the appropriate times. The module is
activated 2 times during a wash cycle.
Detergent is dispensed at the beginning of the
main wash cycle and rinse agent at the
beginning of the final rinse. The
detergent/rinse module can be activated
using Service Mode.

18

Active Vent

If the door is unlatched while running a wash
cycle, the cycle countdown will pause and the
vent will open.

The active vent consists of the wax motor and
housing. The active vent helps to reduce the
noise level and heat loss when in the closed
position. The control module supplies 120
VAC to the wax motor. The control module
reverses polarity to drive the motor in a
clockwise or counter clockwise (open or
closed) direction.

The vent closes about 2 minutes after the
main pump is switched on during the first fill
cycle and opens during the drying cycle
(heated and non-heated). The vent is open
during cool-down periods or when the unit is
not in use.

If the vent is closed and the door is opened
during the wash cycle, the vent will open.
When the door is closed again, the vent will
remain open for 2 minutes, and then close
again to finish the cycle.

It is normal for water vapour to come through
the active vent during the dry cycle. The
active vent can be opened and closed using
the Service Mode.
