ANTI-BACTERIA
(on GLD9312 & GLD8312 models)
11.5 gal., 110 min.
This cycle raises the water temperature in the final rinse to sanitize your dishware. The cycle length
will vary depending on the temperature of your inlet water.
NOTE: The Anti-Bacteria cycle is monitored for sanitization requirements. If the cycle is interrupted
during or after the main wash portion or if the incoming water temperature is so low that adequate
water heating cannot be achieved, the sanitizing conditions may not be met. In these cases, the
sanitized light will not illuminate at the end of the cycle.
NOTE: NSF-certified residential dishwashers are not intended for licensed food establishments.
POTS & PANS
11.5 gal., 96min.
This cycle is meant for heavily soiled dishes or cookware with dried-on or baked-on soils. This
cycle may not remove burned-on foods. Everyday dishes are safe to be used in this cycle.
NORMAL WASH
11.5 gal., 94min.
This cycle is for medium/heavily soiled dishes and glassware.
SPEED CYCLE
3.2gal., 33 min.
This cycle is for everyday dishes and glassware.
CHINA CRYSTAL
4.9 gal., 53 min.
This cycle is specifically designed to reduce the risk of melting plastic items and improve plastic
drying. For removing red tomato-based stains, GE recommends the use of Cascade Plastic.
RINSE & Hold
1.6 gal., 12 min.
For rinsing partial loads that will be washed later. Do not use detergent with this cycle.
NOTE: On the GLD8110 Series models dishwasher have not ANTI-BACTERIA cycle.
NOTE: This dishwasher is equipped with an Sensor; therefore, cycle length and time may vary depending on soil
conditions.
NOTE: Only the Anti-Bacteria, cycle has been designed to meet the requirements of Section 6, NSF 184 for soil
removal and sanitization efficacy.

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.
Before removing the circulation pump, remove the
water from the sump with a syringe.
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 labeled
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 fit only one way on the terminals. Make certain
the connector is fully seated when installing.

HeatingElement
The heating element can be activated using TEST
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. Lower water inlet temperature will
prevent proper convection air movement and
increase drying time substantially.
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.
Heating element Strip Circuit
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.
TestMode
In standby mode, push HI-TEMP, HEATED-DRY and
HI-TEMP WASH, the machine will enter into the process of
Test Mode. After entering the self inspection mode, all
lights will be ON and the display will show 88, then operate
the unit according to the following order:
zTouch the POTS & PANS the inlet water valve will
work for 90 seconds
zTouch the NORMAL, the wash pump will work for 2
minutes and stop for 1 minutes, then repeat.
zTouch the CHINA pad, the detergent dispenser will

zTouch the HI-TEMP pad, the wax motor will work for
1 minute and stop for 1 minute, then repeat.
TurbiditySensor
The turbidity sensor is located in the front of sump.


‐17 ‐

The turbidity sensor measures the amount of suspended
particles in the wash water in the sump. The control sends
the turbidity sensor a pulse width modulated 5 volt signal
for calibration and usage during operation.
Note: If short circuit or open circuit happens to the sensor,
the dishwasher will operate the shortest cycle time, and
may cause the bad wash performance.
By measing the turbidity level, the control module can
conserve energy on lightly soiled loads by skipping
unnecessary cycles.
Turbidity Sensor Circuit
Thermistor
Thermistor is located on the right down side of the sump.
The turbidity’s resistance has a negative temperature

The thermistor’s resistance has negative temperature
coefficient. As the temperature increase, the resistance
goes down. At 75℉,the resistance is approximately 11.6k
Ω. At 140℉, the resistance is approximately 2.7kΩ.
DrainSystem
The drain system cosists of the following components:
zAuxiliary drain pump
zsump
zCheck valve(in line with tube)
zDrain house(includes two drain hose, one with
one-way check valve)
The inlet cover prevents large particles from entering the
sump. Water entering the drain pump is not filtered by the
fine filter(plastic) or by the sump filter(metal & plastic).
The drain pump is mounted on the sump and contains a
one way check valve. The drain pump is controlled by the
control board and can be activated using
Testing Mode.
Auxiliary drain pump stip Circuit
The drain pump utilizes a 120V AC motor. The motor
should read approximately 25Ω
Water Valve and Flood Switch
The water valve is a 120 VAC solenoid valve that is
switched on/off by the control board. The flood switch acts
as a safety switch ONLY and does not control normal
operation of the water valve. The flood switch opens the L
side of the water valve circuit.

The switch is normally open. The weight of the flood

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 valve is secured to the clip by 2 Philips head screw.
Note: To prevent leaks after installation, ensure that hose
to valve connection is good and that clamp is in place.
WaterValveTest
1. Attept to activate water valve using
Test Mode . Pump
out water as necessary using
Test Mode . If an
intermittent failure is suspected, activate water valve 5
times using
Test Mode. Water valve should stay on for
90 to 120 seconds per activation and should not turn
on and off during the 90 to 120 second activation time.
2. If the water valve is not operating properly or water
level is low, check the follow:
zWater valve, flood switch, flood switch float and
stem The flood switch should open when the
water level is approxiaterly 1/4-in. above the
base(bottom) of the float dome.

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 board. Due to
the ribbon length, care must 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 ).
zWhen removing the membrane keypad, peel the keypad from right to left.
zWhen installing, make sure the membrane button areas and lights align with the keypad.
zOn models with an LED display, the display is held in place plastic clip.
Note: When replacing the keypad membrane, always run the Test mode calibrate the keypad membrane to the

The door panel must be removed to access the control board (see D oor 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.
