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, Inc. cannot be responsible, nor assume any liability, for injury or damage of any kind arising from the use of this manual.
OPERATION In order to address service issues with the Electrolux 5000 Series dishwasher, the primary elements of its operation are described below, as well as its physical components. STATIC FILL The cycle begins by activating the drain pump, ensuring the sump is empty.
OPERATION WASH SYSTEM Once filling is complete, the dishwasher enters the pre-wash phase. The pre- wash phase conditions the soil with water and detergent to prepare it for removal in the main wash phase. Once water enters the tub, the pump draws the water into the sump through a primary filter at the Sump bottom of the tub to prevent food from circulating...
OPERATION MAIN WASH / TEMP ASSURE After the final reading by the soil sensor, the unit drains before starting to fill for the main wash. The tub fills, with the wash motor starting after the low level pressure switch is activated. The detergent dispenser now opens, introducing detergent into the wash cycle.
OPERATION RINSE PHASES The first rinse phase following the pre-wash portion of a wash cycle. During this rinse phase, the motor ramps up by 100RPM/second to full speed (2800RPM). Once at full speed, however, the motor will cycle between 1600RPM and 2800 RPM throughout the rest of this rinse phase.
CYCLE, SYSTEMS & COMPONENTS Knowledge of the dishwasher’s cycles and systems is necessary in diagnosing any potential operational problems. Methods for diagnosing these problems, such as taking resistance readings and testing for closed circuits are outlined in the following section as well. DISHWASHER CONTROL All of the functions and operations of this dishwasher are dictated and monitored by the electronic control.
CYCLE, SYSTEMS & COMPONENTS DISHWASHER CONTROL (CONT.) Rinse Hold This cycle is intended for dishes that are to be washed later. It is a rinse-only cycle; options and soil sensing are not available. TESTS FOR THE CONTROL Water/Service Test The service test will check the electronic control’s ability to ran all functions of the dishwasher.
CYCLE, SYSTEMS & COMPONENTS Electronic Control and Keypad Assembly The control on the dishwasher consists of the control board and the switch assembly. The switch is installed into the top of the outer door panel, an elastomer keypad, used to actuate the switch, is inserted into holes in the top of the outer door panel.
CYCLE, SYSTEMS & COMPONENTS To Check Inlet water valve Disconnect dishwasher from power supply. To access electrical connections to valve, remove lower front panel. Using ohmmeter, check between P3-5 (yellow wire) and P3-8 (white wire). The resistance reading of the solenoid coil should be 1126 ohms.
CYCLE, SYSTEMS & COMPONENTS Checking Low Water Level Switch Disconnect power to dishwasher. Gain access to electronic control and check between P3-9 (orange wire) and P3-8 (white wire). This should be an open contact. These wires are connected to center terminal # 1 and terminal to the right of center # 3.
CYCLE, SYSTEMS & COMPONENTS HIGH WATER LEVEL SWITCH (CONT.) Checking High Water Level Switch • Checking continuity through the high water level switch is easier at the control. • Disconnect power to dishwasher. • Gain access to electronic control and check for continuity between the L1 black wire and P3-6 (brown wire).
CYCLE, SYSTEMS & COMPONENTS WASH MOTOR (CONT.) Checking the Wash Motor · Disconnect dishwasher from power supply · Due to the location of the motor disconnect plug, resistance readings should be made at the control - Remove outer door panel to gain access to the control - The run windings for the motor are connected between P3-1 and P3-4...
CYCLE, SYSTEMS & COMPONENTS TEMPERATURE SENSOR AND SOIL SENSOR The electronic control reads information from two sensors to adjust the wash cycle. The Thermistor and soil sensor are integrated into the same housing mounted to the right side of the sump. Both sensors extend into the outer section of the sump to perform independent tasks.
CYCLE, SYSTEMS & COMPONENTS Checking the Soil Sensor · While in idle mode, simultaneously press and hold Heavy Wash and Start / Cancel buttons. - This activates the sensor value test. - If a number does not display, continue with the test. ·...
CYCLE, SYSTEMS & COMPONENTS DISPENSER The dispenser consists of two dispensers in one housing, controlled by the use of one wax motor actuator. The first time the actuator is energized in the cycle, detergent is dispensed. The second time the actuator is energized, rinse agent is dispensed.
CYCLE, SYSTEMS & COMPONENTS FAN DRY UNIT Dishes are dried with a fan driven condensate system. This system is made up of (refer to Figures 20, 21): Fan Dry Motor Air Intake Condensate Duct Condensate Vent As the dishwasher completes its final drain, the fan dry motor forces saturated air across cool baffles in the condensate duct, resulting in the removal of moisture from the air.
SERVICE & DISASSEMBLY SAFETY PRECAUTIONS Always turn off the electric power supply before servicing electrical components, testing with an ohmmeter, or replacing parts. Refer to Safe Servicing Procedures at the front of this manual before servicing the dishwasher. All voltage checks should be made with a voltmeter having a full scale range of 130 volts or higher.
SERVICE & DISASSEMBLY CONTROL Disconnect dishwasher from power supply. Remove outer door panel (see Service and Disassembly section labeled Door Panel). Lay outer door panel face down on a protective surface. Compress plastic retainers with a pair of pliers to release the electronic control from carrier panel (Figure 23).
SERVICE & DISASSEMBLY LOWER ACCESS PANEL Remove bottom kick plate. Remove screws on each side of lower access panel. (See Figure 25) Remove access panel. CAUTION Edges are sharp. Figure 25 Remove these screws DOOR LATCH / DOOR SWITCH Remove outer door panel. (See previous section for detailed instructions.) Remove two screws mounting the latch/switch assembly to inner door panel, and then remove two wires.
SERVICE & DISASSEMBLY UPPER SPRAY ARM The center of the upper spray arm is a locking mount. Turn upper spray arm and mount counterclockwise to remove. (See Figure To reinstall upper spray arm, line up locking posts in center mount with locking tabs on upper spray arm support.
SERVICE & DISASSEMBLY CENTER SPRAY ARM AND UPPER RACK MANIFOLD Remove upper rack and place rack upside down on a flat surface. Place blade of a very thin putty knife between retaining ring and center spray arm. Lightly twist knife to lift arm from retaining ring. (See Figure 30) Remove manifold from rack by compressing tube retainer clips and sliding tube backwards to clear front mount.
SERVICE & DISASSEMBLY UPPER SPRAY ARM MOUNT Replacing upper spray arm mount requires removal of cabinet. See section on cabinet removal for detailed instructions. Set dishwasher upright and remove upper spray arm. The mount pushes into the top of the tub with a rubber grommet. An arm on the mount holds it in place to prevent turning during removal/installation of the upper spray arm.
