Introduction

The new Triton XL Dishwashers are packed with features to get your dishes cleaner, pots and pans spotless, and keep your kitchen quieter... and with a power usage of 477 kWhr/yr, they have an “EnergyStar” rating.

The Triton XL Dishwashers have 3 wash arms that provide complete coverage, eliminating prerinsing, soaking, and scrubbing. The ExtraClean

sensor incorporates a thermistor Auto Temp control and measures the water turbidity in 5 levels of cleanliness. The 100% triple-water filtration, with extra fine filter, eliminates recirculating

food particles. The PiranhaTM hard food disposer grinds and pulverizes any other food particles.

Triton XL Dishwashers run quieter thanks to our QuietPower

motor, P ermaTuf® tub, and the

QuietP ower IV sound insulation, Thinstall. The dual wattage Calrod

heater draws 835 W when it is wet to heat the water faster and, during the drying cycle, drops to 700 W for gentler drying.

The information on the following pages will help you service these new Triton XL Dishwashers effectively and efficiently.

Service Mode

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.

The first time the module is activated (1), the lever slides up the right-hand path of the connecting rod. This action releases the detergent cover. When deactivated (2), the lever returns down the lefthand path and comes to rest under the notch in the center of the connecting rod. At the second activation (3), the lever lifts the connecting rod by the notch. This action lifts the rinse dispenser plunger and releases the rinse agent. When deactivated, the lever returns to its original starting position.

Stainless Steel Bowed Panel (On Some Models)

Disassembly

1. Open the dishwasher door to the fully open (89 degrees open) position.

2. Remove 8 screws (4 screws per side) which hold the outer panel to the door assembly. Be careful not to remove the 2 screws which hold the escutcheon to the door assembly.

3. Slowly close the door.

4. Once the door is closed, remove the 2 screws that connect the bottom of the outer panel to the hinge arms.

5. While holding the outer panel against the door assembly , slowly open the door to about 15 degrees open so the top of the outer panel is in front of the kitchen countertop. If the dishwasher is not installed, the door does not have to be opened.

Do not remove

this screw from

either side.

6. Rotate the bottom of the outer panel out such that the panel is now vertical.

7. Lift up on the stainless steel outer panel such that top corner flanges lift up over the corner cutouts in the escutcheon. Move the panel forward and over the escutcheon so that the panel is totally separated from the door. (See photos of escutcheon and outer panel below .)

Assembly

1. Open the door to about 15 degrees open so that the top of the outer panel is in front of the kitchen countertop. If the dishwasher is not installed, the door does not have to be opened.

2. Lift the outer panel up in the vertical position and hang the outer panel over top of the escutcheon. Take care to ensure that the stainless steel panel corner flanges go over and around the escutcheon corner cutouts.

3. While holding the outer panel to the escutcheon, slowly close the door.

4. With the panel hanging over the escutcheon, rotate the bottom of the stainless steel outer panel back so it is flush with the door assembly. Make sure that the sides of the outer panel fit around the hinge arms.

5. Look at the fit between the escutcheon and the stainless steel outer panel front opening. Make

– 15 –

sure that the protruding ribs from the escutcheon fit inside the stainless steel front opening. Adjust the position of the outer panel up or down, left or right to center the panel with the escutcheon.

6. Once the panel is centered, install the 2 screws in the bottom of the panel to connect the stainless steel outer panel to the hinge arms. Recheck to make sure the escutcheon ribs are protruding through the panel opening.

7. While holding the outer panel against the door assembly , slowly open the door to about 45 degrees open so that the remaining 8 panel screws can be installed (4 screws on each side).

Door Interlock Switch

The door interlock switch opens the L1 circuit and Neutral circuit when the door is open.

Caution: After removing the screws from the escutcheon keypad assembly, the assembly is still attached to the control module by 2 ribbon cables. Dropping or rough handling of the escutcheon will cause the ribbon cable to tear, and the entire escutcheon keypad assembly will need to be replaced.

1. Remove the escutcheon keypad assembly (see

Escutcheon Keypad Assembly

2. Remove 2 screws and the switch from the door.

3. Carefully remove the cover from the switch and unplug the blade connectors.

The bottom door seal is replaceable by removing the outer door panel (see

Door Components

). With the door closed, insert a flat-blade screwdriver under the bottom of the door into the channel and twist to break the bead. Open the door and pull the seal from the channel. To install the seal, snap the seal into the channel, working from one side of the door to the other , until the entire bead is complete and the seal slides freely in the channel.

Drain System

Bottom Door Seal

The drain system consists of the following components:

• Inlet cover

• Sump

• Drain pump (includes motor and one-way check

valve)

• Drain pipe

• Check valve (in line with drain pipe) The inlet cover prevents large particles from

entering the sump. Water entering the drain pump is not filtered by the fine filter (metal) or by the sump filter (plastic). The drain pump is mounted on the sump and contains a one-way check valve. The drain pump is controlled by the control module and can be activated using service mode (refer to the

Service Mode

chapter). The drain pump pushes the drain water out into the drainpipe. The drainpipe contains a one-way check valve.

Turbidity Sensor

The turbidity sensor measures the amount of suspended particles in the wash water in the sump. As the sump water lays between the 1/4- to 3/8inch gap between the LED transmitter and the receptor during the first fill, the baseline reading is taken. Successive turbidity measurements are supplied to the control module and used to determine whether any prewash or rinse cycles can be skipped. Decisions are based on a comparison of clean water measurements at the beginning of the first fill, measurements taken at selected fills, and water temperature. By measuring the turbidity level, the control module can conserve energy on lightly soiled loads by skipping unnecessary cycles.

Note: If the turbidity sensor circuit fails open or shorted, the sensing LED on the control panel will not light and the unit will operate for the maximum amount of time, using the maximum number of wash and rinse fills for the selected cycle.

The turbidity sensor also contains the thermisteor for automatic temperature control.

Keyway and Key

The water valve is a 120 V AC (L1) 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.

Water Valve Replacement The water valve can be replaced with the dish-

washer installed. WARNING: Disconnect power to dishwasher

before proceeding.

1. Turn off water supply to dishwasher.

2. Remove toekick.

3. Disconnect house plumbing from dishwasher.

4. Remove 2 screws and valve from dishwasher frame.

5. Disconnect connector.

Float Dome (removed)

The active vent helps to reduce the noise level and heat loss when in the closed position. The control module supplies +/- 12 VDC to the motor. The control module reverses polarity to drive the motor in a clockwise or counterclockwise (open or closed) direction. The vent is closed during the wash cycle and open during the drying cycle (heated and non-heated) and 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 seven (7) seconds, then close again to finish the cycle.

It is normal for steam to come through the active vent during the dry cycle.

The active vent can be opened and closed using the service mode. Refer to the

Service Mode

chapter. The active vent can be accessed by removing the

escutcheon keypad assembly (see

Keypad Assembly

section).

Factory Test Mode

Factory test mode is the most accurate way to test the turbidity sensor circuit (circuit contains control module, wiring, and turbidity sensor). Factory test mode will test the thermistor (used for Automatic Temperature Control) that is contained in the turbidity sensor and will test the transmitter that is contained in the turbidity sensor .

Entering Factory Test Mode Note: This mode can only be entered within the

first 2 minutes after power-up. After 2 minutes, factory test mode is unavailable.

1. Disconnect power from dishwasher. Wait 10 seconds and connect power to dishwasher.

2. Press the NORMAL WASH keypad and POTS & PANS (or COOK WARE) keypad at the same time for 5 seconds (This step must be performed within 2 minutes of power-up).

3. The following sequence should occur:

a. All LEDs illuminate for a short period of time. b. Water valve activates. The dishwasher will fill

for the appropriate amount of time.

c. Circulation pump activates. The dishwasher

will circulate for approximately 1 minute.

d. Turbidity sensor check. The control module

will check the thermistor circuit, the turbidity (transmitter) circuit, and calibrate itself to the turbidity sensor (transmitter). The turbidity sensor check lasts for 20 to 30 seconds.
