After service is completed, be sure all safety-grounding circuits are complete, a!t electrical connections are secure, and all access panels are in place. TIMER With the timer, user selects the various cleaning cycles of the dishwasher. The timer controls all the electrical functions of the dishwasher in all stages of each cycle.. All functions can be traced on the chart.. Diagram provided in this service manual.. ToTegt Tt_eTinier If the timer is suspected of faulty operation, reference timer chart and electrical schematic diagram and proceed as follows: 1. Index the timer to the first increment of the normal cycle, which is a drain period. 2. If the pump motor fails to operate during the first cycle increment, check for power at the pump motor connector block, if there is no power check the door latch switch, if there is power, check the pump motor as described in this section. 3o If the pump motor does operate, let the timer motor advance the timer through the drain increment to determine if the timer motor and drive train are fully operative. 4. Let the timer advance, or index it forward to the portion of the cycle in question.. 5. If a component controlled by the timer fails to function as the timer advances through the cycle, check for voltage at the timer terminals, tf the check voltage is supplied to the component, check the component as described in this section Continuity through timer contacts, other controls, and wires can also be checked with an ohmmeter with electrical power disconnected. If the timers contacts fail to close in the sequence shown on the timer chart are burned (have resistance measurable with an ohmmeter), or if timer does not advance automatically, replace the timer. To Replace Timer I Disconnect dishwasher from electrical supply 2.. Remove the timer knob.. Library Imaging Sysf,em Figure 1 Figure 2 ., Remove the screws which locking the control panel (See figure 1) Remove the knob and unscrew the two screws which locking the timer on the control panel (See Figure 2,) 4 Take down the damaged timer and JnstalJ a new timer, reverse procedures to complete re ure 3and 4,) Figure 3 Figure 4 DOOR LATCH AND SWITCH ASSEMBLY The latch and switch are located in the door assembly behind the control panel The dishwasher will not operate until the door is closed; the latch engages the door catch To Test Or Replace Door Switch., 1., Disconnect dishwasher from electrical supply,. 2, Remove screws securing the control panel to the inner door (See Figure 1) 3. Remove wire leads from latch switch 4, Use ohmmeter and check switch for continuity, 5 If the switch tests is good, Check dishwasher electrical power Check to see if timer is defective If switch is defective remove door switch from latch assembly, 6. tnstall new switch and reverse procedures to complete repairs, To Replace Door Latch Assembly 1., Disconnect dishwasher from electrica! supply,, 2, Remove screws securing the control panel to the inner door, 3 Remove wire leads from door latch and remove screws securing door latch assembly to inner door (See Figure 5 ) Library imaging System Figure 5 4. Install new door latch assembly and reverse procedures to complete repairs,, FLOAT SWITCHASSEMBLY The water float assembly is located in the right lower side of the dishwasher (the portable located behind the lower front crosspiece).. When too much water enter the dishwasher, the water will enter the float support through the overflow pipe, the float will make the floating .switch acts, the electrical supply to the water valve will disconnected and the drain pump keep on working. If the switch fails to operate, check the following: o Loose connection at the switch terminal • Switch not installed properly. , Warped stem on float, not contacting the actuator blade, , Float support restricts free float movement., ° Check if the float support is cracked .
