LOW WATER SENSING automatically de-energizes the heating element if the water in the cookpot drops too low. When the water level in the cookpot is below the sensor probes, such as when draining and cleaning the cookpot, the controller display will read LO. NORMAL WATER LEVEL SENSING, on units configured with the AutoFill feature, automatically adds water during or after a cooking cycle if the water level is low. With this automatic filling feature, the water level does not have to be continuously monitored.
When the water is at or above the minimum temperature for boiling (transition temperature), the controller pulses power to the elements at a programmable rate. The range can be set between 0 and 9. The default setting is 5. When the water temperature is below boiling point, the power application is 100 percent. To set the Transition Temperature/Boil Intensity: 1. Verify that the controller is OFF (the display is blank). 2.
3.1.4 Controller Simmer Mode Adjustment NOTE: The SMS III Controller simmer temperature is adjustable from 185ºF to 215ºF (85° to 102°C). There are two versions of this controller; one is adjusted by programming, the other is manually adjusted. To determine which version of the controller you have, turn the controller off by pressing the ON/OFF switch. The display will go blank. Press the Simmer (right thermometer icon) switch.
Press the Boil Mode switch to display the cookpot temperature. If an F follows the temperature, the display is in Fahrenheit; if a C follows the temperature, the display is in Celsius. 3.1.6 Shutting the 17EC/17ECS Down switch.

ELECTRIC COOKER MODELS 17EC, 17ECS, ESW AND EWBS CHAPTER 6: 17EC/17ECS SERVICE PROCEDURES & PARTS 6.1 Functional Description The 17EC Electric Cooker contains a 16.5-gallon (62.5-liter) stainless steel cookpot. The water in the cookpot is heated by a pair of 8.5-kilowatt heating elements. Electrical power to the elements is controlled by a solid-state SMS III Spaghetti Magic computer specifically modified for this application.
6.2 Accessing Equipment for Servicing DANGER Moving this equipment while it is filled with hot water may cause spilling or splattering of the hot water. Always drain the cookpot before attempting to relocate this equipment for servicing. 1. Disconnect the unit from the electrical power supply and from the water supply. 2. Remove any attached restraining devices. 3. Relocate the unit for service accessibility. 4.
5. Replace the component box covers, being sure to reconnect the ground wire. Reconnect the cooker to the electrical power supply. 6.3.3 Replacing a Heating Element 1. Drain the cookpot and disconnect the cooker from the electrical power supply. Disconnect the unit from the water supply at the rear of the cooker. Remove the basket lift arms from the unit. 2. Reposition the cooker to allow clear access to the rear of the unit. Remove the upper and lower basket lift panels. 3.
8. Insert the pins on the element leads into the element connector in accordance with the illustration below. The insulation on the lead will be flush with the face of the plug when properly positioned. When all leads are positioned correctly, close the connector and verify that the tabs are locked in place. Each element lead is marked with a number that corresponds to the hole in the connector into which it should be inserted.
5. Loosen the small compression nut in the large fitting on the replacement thermostat so that the large fitting will move freely on the capillary tube (the thin, flexible tube). Carefully insert the replacement thermostat into the cookpot, being careful not to bend the thermostat tube. Position the tube along the inside of the left leg of the element (as viewed from the front of the cooker) and secure it in place with two metal wire ties.
4. Remove the temperature probe by unscrewing it from the front of the cookpot. 5. Apply thread sealer to the replacement probe and screw it securely into the cookpot. 6. Insert the red probe lead into position 13 of the 15-pin connector and the white lead into position 14. Pull gently on each lead to ensure it is firmly seated. Insert red lead into position 13. Insert white lead into position 14. 7.
3. If replacing the regulator, adjust the replacement regulator output pressure to not more than 40 PSI (28.15 kg/cm2) before installation in the cooker. 4. Recover the fittings from the failed component (regulator or solenoid valve) and install them on the replacement, using thread sealer on all connections. 5. Reverse Steps 1 and 2 to complete the procedure, being sure to apply thread sealer to all connections.
2. If rigid water connections have been used, disconnect the cooker from the incoming water supply. 3. Remove the basket lift arms from the lifter rods and then reposition the cooker to gain access to the rear. Remove the upper and lower basket lift rear panels. 4. Unplug the basket lift wiring harness from the lower 6-pin connector on the component box. (To do this, you must reach around behind the component box from the front of the cooker.) Disconnect basket lift wiring harness from this connector. 5.
6.3.10 Replacing the Cookpot or Rinse Tank Remove these four screws. 1. Remove the faucet assembly from the cooker in accordance with Steps 1-4 of Section 6.3.8. 2. Remove the screws that secure each of the rear corners of the backsplash assembly (see illustration at right). NOTE: To access the screw in the lower right corner (as viewed from the rear) remove the upper basket lift panel. 3. Remove the screws along the top edge of the control panel and open the panel by swinging it downward.
9. Invert the cookpot or rinse tank on a suitable work surface and remove the salvageable components (e.g., elements, thermostats, drain plumbing, etc.). Install the recovered components on the replacement cookpot or rinse tank, using thread sealer on all connections. 10. Reverse Steps 1 through 8 to complete the procedure. 6.4 Troubleshooting NOTE: 24VAC power to the electronic components of this system is controlled by the master ON/OFF switch located on the front of the contactor box.
24VDC required by the basket lift relay and the solid-state heating relays. The computer signals for heat via Pin 4, grounds the solenoid valve via Pin 6, and senses water level via Pins 7 (low) and 9 (full). The temperature probe connects to Pins 13 and 14. The basket lift relay connects to Pins 10 and 12. The sound device connects to Pin 11. 6.4.
The temperature probe is used only when the unit is in the simmer mode. When the operator selects the simmer mode, logic circuits in the computer monitor the temperature of the water and cycle power to the element on and off as required to maintain the temperature at the setpoint programmed into the computer. The contactor is the terminal block to which the element leads are connected and where actual contact is made between the leads and the line voltage.
6.4.6 Technician Troubleshooting Guides TROUBLESHOOTING THE 24VAC POWER SUPPLY SYSTEM The primary indicator of a problem with the 24VAC Power Supply System is a failure of the computer to activate when the master ON/OFF switch is placed in the ON position and the computer ON/OFF switch is pressed. Verify that the power cord is properly connected to the electrical service and that the circuit breaker is not tripped. Place the master ON/ OFF switch in the ON position.
TROUBLESHOOTING THE 24VAC POWER SUPPLY TO THE COMPUTER Place the master ON/ OFF switch in the OFF postion, then back in the ON postion. Press the ON/OFF switch on the computer. Did the computer activate? No Was there an audible snap from the contactor indicating the coil energized? No There is a problem in the 24VAC Power Supply System. Refer to the troubleshooting guide on Page 6-14. Yes Is 24VAC present across Pins 1 and 2 of the wiring harness? Yes Yes 24VAC is reaching computer.
TROUBLESHOOTING THE AUTOFILL SYSTEM Verify that unit is connected to the water supply and that water supply is turned on. Drain the water in the cookpot to a level below the upper water-level sensor. Place the master ON/OFF switch in the ON position. Press the computer ON/OFF switch. Did unit begin to fill? No Remove the waterlevel sensor guard and thoroughly clean the sensors. Did unit begin to fill? Is voltage across Pins 2 and 6 of computer 15-pin connector zero? No No Check sensor and wiring.
TROUBLESHOOTING THE WATER HEATING SYSTEM Each of the following checks is to be performed with the unit connected to the electrical power supply, with the computer ON and calling for heat, and with at least enough water in the cookpot to cover the lower water-level sensor. CHECKING THE TEMPERATURE PROBE (Because water boils in Simmer Mode or water is too cool in Simmer Mode.) CHECKING THE HIGH-LIMIT THERMOSTAT Is resistance between Pins 5 and 8 of the 15-pin plug 1 ohm or less? No High-limit has failed.
TROUBLESHOOTING THE BASKET LIFT SYSTEM If the basket lift motors are activating, but the basket lift fails to raise or lower, or if its movement is erratic, the probable cause is jamming or binding of the basket lift rods. Apply a light-weight white grease (such as Lubriplate TM ) to the rods. If this does not correct the problem, check for bent or otherwise damaged rods and links, and for loose bellcranks. TROUBLESHOOTING THE BASKET LIFT Is 5-Amp fuse in the component box OK? No Replace fuse.

ELECTRIC COOKER MODELS 17EC, 17ECS, ESW AND EWBS CHAPTER 7: ESW & EWBS SERVICE PROCEDURES & PARTS 7.1 Functional Description The ESW series was the predecessor to the EWBS series. Both cookers are very similar in construction and function. The cookers in the ESW series have rocker-switch controls only. These cookers were configured as single units or as batteries of two units.
NOTE: The cooker has a high-limit safety. If the water in the cookpot falls below the low-waterlevel sensor but the sensor remains grounded for whatever reason (thereby allowing the element to continue to heat), the high-limit switch will open when the element temperature reaches 400 ±15ºF. This cuts off power to the element. Units with Computer Controls When the computer POWER switch is pressed, a logic circuit in the computer checks the water level in the cookpot.
7.2 Accessing Equipment for Servicing DANGER Moving this equipment while it is filled with hot water may cause spilling or splattering of the hot water. Always drain the cookpot before attempting to relocate this equipment for servicing. 1. Disconnect the unit from the electrical power supply and from the water supply. 2. Remove any attached restraining devices. 3. Relocate the unit for service accessibility. 4.
7.3.3 Replacing the Heating Element 1. Drain the cookpot and disconnect the cooker from the electrical power supply. Disconnect the unit from the water supply at the rear of the cooker. Remove the basket lift arms from the unit. 2. Reposition the cooker to allow clear access to the rear of the unit. Remove the cabinet back (on units with basket lifts, remove all three back panels). 3. Unplug the 6-pin element connector from the rear of the contactor box.
Hole 6 Lead 1 Note D-shaped pin and "pip" identifying Hole 1. 9. Bundle all six element leads together and secure with plastic wire ties close to the element and connector, and in the middle. 10. Plug the connector into the contactor box. Reverse Steps 1 and 2 to complete the procedure. 7.3.4 Replacing the High-Limit Thermostat 1. Drain the cookpot and disconnect the cooker from the electrical power supply. Disconnect the unit from the water supply at the rear of the cooker.
6. Coil the capillary tube as necessary to achieve a neat installation and attach the terminal block to the mounting bracket using the screws removed in Step 4. Connect thermostat lead 5C (black) to the normally closed (NC) terminal and 8C (white) to the common (C) terminal. Common (C) Terminal (Note open side.) Normally Closed (NC) Terminal (Note closed side.) 7. Reverse Steps 1 and 2 to complete the procedure. 7.3.
6. Carefully work any slack in the capillary tube back out of the hole in the cookpot. Apply thread sealer to the threads of the replacement temperature probe fitting and screw the fitting into the cookpot. When the fitting is tight, verify that all slack in the capillary has been worked back out of the cookpot and that the bulb is correctly positioned under the lower portion of the retaining bracket. Then, and only then, tighten the small nut in the center of the fitting.
Hole 8 Note D-shaped pin and rib identifying Hole 1. Hole 6 7. Reattach the 12-pin connector to the interface board, close the control panel, and replace the two screws removed in Step 2. 7.3.7 Replacing the Pressure Regulator or Solenoid Valve 1. Drain the cookpot and disconnect the cooker from the electrical power supply. If necessary, reposition the cooker to allow free access to the component to be replaced. Turn off or disconnect the water supply to the cooker.
7.3.8 Replacing the Water Faucet 1. Drain the cookpot and disconnect the cooker from the electrical power supply. 2. Turn off the water supply to the cooker and disconnect the incoming faucet water line where it attaches to the pipe nipple at the pressure regulator. Reposition the cooker to gain clear access to the rear of the cooker. 3. Remove the cabinet back (or, if the unit is equipped with basket lifts, remove the upper rear panel). 4.
4. Remove the four bolts securing the motor mount to the frame, then remove the motor and mount assembly from the unit. NOTE: It is possible to replace a motor or the microswitch without removing the motor and mount assembly, but it is much more difficult. 5. Dismount the motor or microswitch as shown below and install the replacement. NOTE: The right motor and microswitch dismount in the same way as the left. Loosen setscrew in bottom of cam (bell crank). 6. Reverse Steps 1-4 to complete the procedure.
b. Unplug the 5- and 12-pin connectors from the interface board. Do not disconnect the water level sensor leads from the interface board. c. Remove the interface board bracket from the unit. d. Using a pin pusher, push out the temperature probe leads from holes 6 and 8 on the 12-pin connector. 4. Disconnect the Autofill water supply piping at the cookpot compression fitting. 5. Remove the screws that secure the topcap to the cabinet and remove the topcap from the unit.
7.4 Troubleshooting Problems with this equipment may be grouped into five broad categories: 1. 2. 3. 4. 5. Failure or malfunction of a 24VAC Power-Supply System component. Failure or malfunction of a Control System component. Failure or malfunction of an Autofill/Autoskim System component. Failure or malfunction of a Water Heating System component. Failure or malfunction of a Basket Lift System component (on units so equipped). Sections 7.4.1 through 7.4.
7.4.3 How the Autofill and Skim Systems Work The heart of the automatic filling (Autofill) system is a normally closed solenoid valve that opens when 24VAC is applied as a result of the loss of upper water-level sensor ground. The ground is lost when the sensor is not in contact with water in the cookpot. Starch or lime build-up on the sensor may keep a ground from forming.
required to maintain the temperature at the setpoint programmed into the computer or set on the thermostat knob. The contactor is the terminal block to which the element leads are connected and where actual contact is made between the leads and the line voltage. Built into the contactor is a 24VAC coil that energizes when signaled by the computer or interface board that the water temperature is below the setpoint.
7.4.6 Technician Troubleshooting Guides TROUBLESHOOTING THE 24VAC POWER SUPPLY SYSTEM Verify that the power cord is properly connected to the electrical service and that the circuit breaker is not tripped. The primary indicator of a problem with the 24VAC Power Supply System is a failure of the power light to illuminate when the POWER switch is placed in the ON position or the failure of the computer to activate when the computer ON/OFF switch is pressed.
TROUBLESHOOTING THE AUTOFILL SYSTEM Verify that unit is connected to the water supply and that water supply is turned on. Drain the water in the cookpot to a level below the upper water-level sensor. Place the POWER switch in the ON position. In units with computers, press the computer ON/OFF switch. Did unit begin to fill? No Remove the waterlevel sensor guard and thoroughly clean the sensors.
TROUBLESHOOTING THE WATER HEATING SYSTEM Each of the following checks is to be performed with the unit connected to the electrical power supply, with the unit ON and calling for heat, and with at least enough water in the cookpot to cover the lower water-level sensor. CHECKING THE TEMPERATURE PROBE (on units with computers because water boils in Simmer Mode or water is too cool in Simmer Mode.
TROUBLESHOOTING THE BASKET LIFT SYSTEM TROUBLESHOOTING THE BASKET LIFT With the basket lift in the UP position, is 27-33VDC present at Pin 7 or 9 of IFB 15-pin connector (0 volts if in DOWN position)? If the basket lift motors are activating, but the basket lift fails to raise or lower, or if its movement is erratic, the probable cause is jamming or binding of the basket lift rods. Apply a light-weight white grease (such as LubriplateTM ) to the rods.
