SAFE SERVICING PRACTICES - ALL APPLIANCES

To avoid personal injury and/or property damage, it is important that Safe Servicing Practices be observed. The following are some limited examples of

safe practices:

1. DO NOT attempt a product repair if you have any doubts as to your ability to complete it in a safe and satisfactory manner.

2. Before servicing or moving an appliance:

 Remove the power cord from the electrical outlet, trip the circuit breaker to

the OFF position, or remove the fuse.  Turn off the gas supply.  Turn off the water supply.

3. Never interfere with the proper operation of any safety device.

4. USE ONLY REPLACEMENT PARTS CATALOGED FOR THIS APPLIANCE.

SUBSTITUTIONS MAY DEFEAT COMPLIANCE WITH SAFETY STANDARDS SET FOR HOME APPLIANCES.

5. GROUNDING: The standard color coding for safety ground wires is GREEN, or GREEN with YELLOW STRIPES. Ground leads are not to be used as current carrying conductors. It is EXTREMELY important that the service technician reestablish all safety grounds prior to completion of service. Failure to do so will create a hazard.

6. Prior to returning the product to service, ensure that:

 All electrical connections are correct and secure  All electrical leads are properly dressed and secured away from sharp

edges, high-temperature components, and moving parts

 All non-insulated electrical terminals, connectors, heaters, etc. are

adequately spaced away from all metal parts and panels

 All safety grounds (both internal and external) are correctly and securely

connected

 All panels are properly and securely reassembled

ATTENTION!!!

This service manual is intended for use by persons having electrical and mechnical training and a level of knowledge of these subjects generally considered acceptable in the appliance repair trade. Electrolux Home Products cannot be responsible, nor assume any liability, for injury or damage of any kind arising from the use of this manual.

WHAT'S NEW

Ö COLLAPSIBLE TOWER - Single wash arm on low end models with collaspsible tower that is molded into the

spray arm. This tower retracts completely into the lower arm giving added area in the lower rack.

Ö VENT COVER- The vent cover has the gasket molded into the cover to prevent water leaks.

Ö PUMP AND MOTOR ASSEMBLY - The wash pump and motor are in one piece and is not repairable. The new

design motor does not have nor need a seal to prevent water leaks. In the end of this motor is a small circuit board that is designed to make sure that the motor will always start in the proper direction. This new motor is mounted with a new mounting bracket that only requires two screws.

Ö SANITIZE RINSE - On the higher end models, a sanitize rinse setting has been added and the rinse temperature

will reach 150°F.

CONSTRUCTION & OPERATION

WATER DISTRIBUTION SYSTEM

The water distribution system consists of an upper and lower spray arm, upper (spray) arm delivery tube, filter, soil director, pump, sump, and check ball. The system is designed to operate only one spray arm at a time. During the first wash and first and second rinses, only the lower spray arm operates. In the second wash, third and fourth rinses the spray arms alternate about every 90 seconds.

This alternating of the spray arms is achieved with a check ball located on a ramp between two outlets of the pump. There is an outlet to the bottom spray arm and an outlet to the upper arm delivery tube. In the normal position the ball is at the bottom of the ramp, in front of the opening to the upper arm delivery tube.

the ball and enter the tube, and fills the tube at a rate of approximately four inches a second. At the same time, the outlet to the lower spray arm is open, so the lower spray arm operates. When the pump stops, the pressure is removed from the ball and the water flows down the tube, forcing the ball up the ramp and against the outlet to the lower spray arm. If the pump remains off for more than 3 seconds, all the water in the tube escapes and the ball returns to the bottom of the ramp. But, if the pump is started in less than .6 seconds, the water from the upper arm delivery tube is still forcing the ball up the ramp against the outlet to the lower spray arm. The force of the water from the pump continues to hold the ball against the outlet to the lower spray arm which leaves the outlet to the upper arm delivery tube open. When the ball is in this position only the upper spray arm operates. This momentary stopping of the pump is controlled by a contact in the timer.

Another unique feature of the water distribution system is the two cavities of the sump. One cavity provides filtered water to the pump for recirculation through the spray arms. The other, called a quiet water cavity, allows soil to collect in the area of the macerator blade, where it is held until the drain pump removes it.

When the pump starts, the force of the water pushes the ball to block the opening to the upper arm delivery tube.

WATER DISTRIBUTION COMPONENTS Wash Pump

The recirculation (wash) pump has three (3) functional parts, a 1/12th HP drive motor, impeller, and macerator blade. The pump circulates water at the rate of 12 gallons per minute. This pump is used only during the wash cycle, a separate pump is used during the drain cycle. The wash pump is to be replaced as a complete assembly.

Not all of the water is blocked however. The opening is constructed to allow a small amount of water to bypass

Page 13

Upper Spray Arm

The upper spray arm hangs from a bracket that is snapped to the upper rack. The water is supplied to the arm with a nozzle and funnel arrangement. The nozzle is located at the top of the tub and the funnel is located directly below it and directs water into the arm. All the spray jets but three face up.

Lower Spray Arm

The lower spray arm rotates on the lower spray arm support. It has two functions, washing the dishes and cleaning the filter. The jets located on the top of the arm clean the dishes and propel the arm. The three (3) jets located on the bottom of the arm are aimed to flush the soil on the filter toward the glass trap and soil director.

Filter

Two types of filter materials are used, molded polypropylene and stainless steel, depending on the model.

Polyproplene filter

This is a molded filter consisting of two parts; the filter, which covers the entire sump, plus an inner basket, which directs food soil to the drain portion of the pump. The inner basket can be constructed of fine polyester mesh or polypropylene around the sides of the basket. The bottoms of both baskets are open to allow the soil to enter the drain portion of the pump.

Lower Spray Arm With Collapsible Tower

The spray arm rotates 100% of the time with the tower assembly fully extended during the wash and rinse cycles. The arm has two functions; washing the dishes and cleaning the filter. The jets, located on the top of the arm, clean the dishes and propel the arm. The two jets located on the bottom of the arm are aimed to flush the soil on the filter toward the soil director.

Stainless Steel Filter

The stainless steel filter covers the entire sump area with an inner basket of fine mesh polyester. The bottom of this basket is open to allow food soil to enter the drain portion of the pump.

Page 14

Drain Pump

The only function of the drain pump is to remove water from the dishwasher. It is driven by a 1/25th HP drive motor. It consists of 3 function parts; a pump cover, impeller and armature, and stator. The pump only comes as an assembly. The pump cover can be removed for easy cleaning of the pump.

Drying System

Static Vent

The drying system on the dishwasher can employ one of three types of systems:

1. Static Dry System - The vent is located on the

upper left-hand side of the door and is open at all times. This allows the warm, moist air to escape out the vent grill. Air is drawn into the dishwasher tub through the opening across the bottom of the door.

2. Active Vent System - The vent is closed up until the

start of the dry cycle, at which time the vent is opened and the warm, moist air is allowed to escape. Also, the air is brought into the tub through the bottom of the door.

3. Power Vent System - This system is the same as

the Active Vent System but with the addition of a blower motor. At the beginning of the dry cycle, the vent opens and a small motor with a centrifugal blower starts, accelerating the movement of air from the dishwasher.

Active Vent

Power Vent

The door vent actuator opens the vent only during the dry cycle. It is closed during all other cycles to minimize heat loss and to prevent noise from being transmitted into the kitchen.

Page 15

DRYING SYSTEM COMPONENTS Lower Vent Housing

The lower vent housing is located between the inner door assembly and control housing and is mounted to the inner door panel. It surrounds an opening in the inner door panel. The opening is covered with a moveable vent valve.

Vent Valve

The vent valve is a rectangular rubber covered pad slightly larger than the opening. The vent valve is attached to the vent actuator which is electrically operated.

Vent Actuator

The actuator is made up of a rod, slide, wax motor , and spring. The valve is attached to one end of the rod and the slide is inserted in the other. The spring pushes in on the slide forcing the rod to push the valve against the opening in the door panel.

When the timer enters the dry cycle, 120 VAC is applied to the wax motor. The wax motor is made up of a heating disk, wax chamber and piston. When voltage is applied to the heating disk, the wax in the chamber heats causing the wax to expand, driving the piston out. The piston forces the slide out causing the vent valve to open.

The vent actuator is replaced as a complete assembly. No individual replacement parts are available.

Blower

Models that feature Fan Assisted Dry use a small motor and centrifugal blower assembly which is mounted to the top section of the lower vent housing.

Upper Vent Housing

The upper vent Housing is screwed to the blower and directs air from the blower to the outlet in the console.

Models that do not have a blower use a different upper vent housing which connects directly to the lower vent housing.

DISPENSING SYSTEM Detergent & Rinse Aid Dispenser

The detergent & rinse aid dispenser consists of two dispensers combined in one housing that are controlled with one wax motor actuator. The first time the actuator is energized in a cycle, it dispenses detergent. The second time the actuator is energized, it dispenses rinse aid. The amount of rinse aid dispensed can be adjusted from one to four (1 - 4) by using a pointer under the fill cap. The dispenser is replaced as a complete assembly. No individual replacement parts are available.

Dispenser Operation

The dispenser has two detergent cups:

1. A cup with a spring loaded cover with a manual or automatic release latch.

2. A cup formed in the inner door panel without a cover.

Prior to starting the dishwasher, detergent is added to the dispenser cup and the cover is latched close. The open cup is also filled but empties into the tub as soon as the door is lifted to the upright position.

The detergent in the covered cup is held until the start of the second wash. The timer then supplies 120 VAC to the dispenser actuator for one minute. It takes 30 seconds for the actuator to move the pivot arm far enough to release the cover. When power is applied to the actuator, the actuator plunger pushes the end of the pivot arm down. The pivot arm rotates on the shaft of the detergent dispenser door latch. As the shaft rotates, it turns the door latch , releasing the spring loaded cover.

The pivot arm is spring loaded so that when power is removed, it returns to the normal (horizontal) position. The other end of the pivot arm has a pin that moves in a slot(s) of the rinse injector pump arm. The rinse injector pump arm is slotted in such a way that when the actuator pushes the lever down the first time to release the detergent cup cover, the pin moves up but does not raise the rinse injector pump arm. When the timer removes power from the actuator, the spring forces the rinse injector pump arm end of the pivot armdown. The compond slot in the rinse injector pump arm directs the pivot arm pin down the front of the rinse injector pump arm and under a shorter slot in the center of the arm. When the timer reaches the middle of the final rinse cycle, it again applies 120 VAC to the dispenser actuator which forces the pivot arm up at the rinse injector end. As the pin engages the shorter slot, it raises the rinse injector pump arm which operatesthe pump. When the power is removed, the pivot arm spring forces the pin to the bottom of the slot. A leaf spring pushes the rinse injector pump arm to the left so that the pin returns to the original starting position.

DOOR LATCH ASSEMBLY

The door latch assembly has two functions; one is to lock the door in a closed position and the other is to operate the door switches.

The door latch assembly consists of the door handle, door handle bracket, door catch, door switch bracket, and door switches. The assembly is secured to the inner door panel with two locater pins and two screws. The panel is hidden by and accessed through the control panel.

When the door is closed, the door strike (mounted on the tub) forces the spring loaded catch to rotate back until the bottom of the catch clears the door handle bracket. At that time, the spring forces the door handle bracket to rotate. The bar at the top of the door handle rotates back under the door catch locking the door. The plunger on the bottom of the bracket rotates forward, closing the door switches.

The door is released by lifting up on the door handle. When the handle is lifted up, the door handle bracket rotates in at the top, allowing the door catch to rotate open, and out at the bottom to open the door switches. When the catch is rotated to the open position, it holds the door handle bracket away from the door switches.

Page 17

Selector Switch and Thermostats (Mechanical Timer Models)

Depending on the model, the selector switch could be a rocker selector switch with two selections or a push button selector switch with from two to eight buttons and consisting of from one to four switches.

Heated Dry

If the dishwasher has an option for "Heated Dry", this switch will be in series with the element. When the timer advances to the dry portion of the cycle, contacts will close to apply power to the heating element. When "ON" is selected, the contacts in the switch will be closed, applying power to the element. If "OFF" is selected, the contacts in the switch will be open.

Hi-Temp Wash

The selector switch has a selection for Hi-Temp Wash; the switch is in parallel with a thermostat mounted on the bottom of the tub and with a contact in the timer. The selector switch, temp assure thermostat, and the temp boost thermostat are all in series with the timer motor. Both thermostats are normally open thermostats. When the timer reaches the end of the second wash cycle, the contact in the timer supplying power to run thetimer motor will open. At which time, if the selector switch for the Hi-Temp Wash has been selected, power to run the timer motor must come through the thermostats. The temperature of the water in the tub must rise to 137° ± 5° F for the thermostat to close and the timer motor to advance. If the water temperature is below 137° ± 5° F, the timer will pause until the heating element raises the temperature of the water in the tub and allow the thermostat to close.

Hi-Temp Rinse

If the selector switch was a selection for a Hi-Temp rinse, the switch is in parallel with a thermostat mounted in the tub, and the contact in the timer, the same as the Hi-Temp wash. The operation for the Hi-Temp rinse will be the same as for the Hi-Temp wash with the exception, on some models, the temperature of the water in the tub will be 150° ± 5° F for the thermostat to close to give a sanitizing rinse.

High Limit Thermostat

The High Limit Thermostat is mounted on the bottom of the tub in the left rear. This thermostat is a normally closed thermostat. It is used as a safety in the event of a component failure in the dishwasher. The thermostat will open at 200°F and will reset at 100°F.

Page 18

DISHWASHER LEVELING

The dishwasher used four hex shaped leveling legs. They allow the dishwasher to be leveled to any type of flooring. The tops of the legs are tapered to 3/16" hex so a wrench or socket may be used to adjust the legs from the top of the leveler.
