This has two purposes. The first one is to energize both the timer motor and the indicator light LC (20042). The second purpose is for CR2 to bypass the Start Switch 1 TC. 2- The timer motor is energized and starts to turn and closes the first contact M1 (20518) which will bypass the small relay contactor and keep the timer motor running during the entire cycle. 3- As the timer cam continues to turn, the second switch M2 (20518) is closed and energizes the wash pump motor. 2 2 4- After 150 seconds approximately, switch M2 opens and switch M3 (20518)closes to energize the solenoid valve (for rinsing), the drain pump and the detergent pump. This function lasts about 20 seconds and the circuit reverts to the beginning. 3 4 15 F-18 Base component location View from under of the dishwasher 20199 40229 RINSE-AID DRAIN PUMP PUMP 1 888 275 4538 - 611 514 737 9701 - 611 FAX 514 737 2792 20588 DETERGENT PUMP May 2004 60137 Drain Plug 60004 Gasket 15689 BOOSTER TANK RINSE WATER 15019 BOTTOM HUB WASH-ARM SUPPORT 10349 (F18-DP) 10351 (F18) DRAIN CONNECTION FRONT 20569 WATER SOLENOID VALVE 40240 WASH PUMP 20582 TERMINAL BLOCK 16 1 888 275 4538 - 611 514 737 9701 - 611 FAX 514 737 2792 WASH SYSTEM TL- Power Switch PS- Pressure Switch SW2- Drain Switch CR1 + CR2 - Micro Relay Switches M1 + M2 + M3: Timer Cam Switches TC- Start Switch MP - Door Switch TB - Thermostat TV - Thermostat CCB - Booster Contactor Contacts ELB - Solenoid Coil PD - Soap Pump BR - Micro Relay coil BCB - Booster Contactor coil RV - Wash Tank Heater Element RB - Booster Tank Heater Element DP - Drain Pump MT - Timer Motor MPL - Wash Pump Motor LL - Indicator Light - Power LC - Indicator Light - Wash Cycle LP - Indicator Light - Temperature Ready CA - Capacitor - wash pump 17 1 888 275 4538 - 611 514 737 9701 - 611 FAX 514 737 2792 WASH SYSTEM Wash Rinse 18 1 888 275 4538 - 611 514 737 9701 - 611 FAX 514 737 2792 WASH SYSTEM WASH PUMP . . . 40240 9A-9BMECHANICAL SEAL . . . . 40030 7A-7BPUMP BOTTOM HOUSING . . . . 40218 11 PUMP HOUSING . . . . 40083 10 IMPELLER . . . . 40269 12 GASKET . . . . 40113 19 DRAIN PUMP 40229 1 888 275 4538 - 611 514 737 9701 - 611 FAX 514 737 2792 40128 TL- Power Switch PS- Pressure Switch SW2- Drain Switch CR1 + CR2 - Micro Relay Switches M1 + M2 + M3: Timer Cam Switches TC- Start Switch MP - Door Switch TB - Thermostat TV - Thermostat CCB - Booster Contactor Contacts ELB - Solenoid Coil PD - Soap Pump 40115 BR - Micro Relay coil BCB - Booster Contactor coil RV - Wash Tank Heater Element RB - Booster Tank Heater Element DP - Drain Pump MT - Timer Motor MPL - Wash Pump Motor LL - Indicator Light - Power LC - Indicator Light - Wash Cycle LP - Indicator Light - Temperature Ready CA - Capacitor - wash pump 40129 40127 Drain opening in wash tank 20 Drain Pump Location 1 888 275 4538 - 611 514 737 9701 - 611 FAX 514 737 2792 F18 Booster Do not connect Do not connect 21 TL- Power Switch PS- Pressure Switch SW2- Drain Switch CR1 + CR2 - Micro Relay Switches M1 + M2 + M3: Timer Cam Switches TC- Start Switch MP - Door Switch TB - Thermostat TV - Thermostat CCB - Booster Contactor Contacts ELB - Solenoid Coil PD - Soap Pump BR - Micro Relay coil BCB - Booster Contactor coil RV - Wash Tank Heater Element RB - Booster Tank Heater Element DP - Drain Pump MT - Timer Motor MPL - Wash Pump Motor LL - Indicator Light - Power LC - Indicator Light - Wash Cycle LP - Indicator Light - Temperature Ready CA - Capacitor - wash pump 1 888 275 4538 - 611 514 737 9701 - 611 FAX 514 737 2792 22 1 888 275 4538 - 611 514 737 9701 - 611 FAX 514 737 2792 ELECTRICAL SEQUENCE As the unit is powered by the Power Switch (1), it energizes LL(2). The Pressure-switch PS energies the solenoid valve ELB (to fill the wash tank), the detergent pump PD and the drain pump DP. When the pressure-switch PS(20058) is satisfied, it energizes the Booster relay contactor BCB(20104) by the rinse thermostat TB(20596). 23 1 888 275 4538 - 611 514 737 9701 - 611 FAX 514 737 2792 When the Booster thermostat TB is satisfied, it energizes the wash tank heater element RV by the wash thermostat TV. When the thermostat in the wash tank is satisfied, it energizes the indicator light LP. 24 1 888 275 4538 - 611 514 737 9701 - 611 FAX 514 737 2792 When the Start Cycle TC (6-20519) button is depressed. The small contactor relay (20067) is energized and closes contacts CR1 and CR2. This has two purposes. The first one is to energize both the timer motor and the indicator light LC (7). The second purpose is for CR2 to bypass the Start Switch TC. The timer motor MT is energized and starts to turn and closes the first contact M1 which will bypass the small relay contactor and keep the timer motor running during the entire cycle. 25 1 888 275 4538 - 611 514 737 9701 - 611 FAX 514 737 2792 As the timer cam continues to turn, the second switch M2 is closed and energizes the wash pump motor MPL(40240).
