Chapter 3: Service, Maintenance, And Adjustments

This chapter provides the qualified technician with the troubleshooting and replacement procedures
necessary to service the counter top cooker. If your cooker does not perform properly after
performing main tenance, contact your authorized service center. For repair, maintenance, or an
explanation of any procedure, contact your dealer, local service company, the factory representative
in your area, or the factory.

The power supply must be disconnected be fore servicing or cleaning the cooker.

3.1 THERMOSTAT CALIBRATION
The Pasta Perfect cooker is equipped with a thermostat that controls the heating element when the

FUNCTION SELECT switch is in the SIMMER position. This thermostat should be set at
approxi mately 195°F. To change the thermostat setting, use the following procedure:

a. Place an accurate mercury thermometer in the center of the cooking tank with the bulb

approximately 3" below the surface of the water. Allow enough time for the thermometer to
stabilize.

b. Using a flat tip screwdriver, turn the shaft on the thermostat clockwise to decrease the

temperature setting; turn the shaft counterclockwise to increase the temperature setting. The
thermostat is located on the lower right front wall of the tank. The shaft should not need to
be turned more than 1/4 turn to adjust the temperature setting.

CAUTION

DO NOT turn the adjusting shaft more than two (2) turns in either direction.

3.2 CHECKING AND REPLACING FUSES
A general purpose ohmmeter or continuity checker is needed to check the heating element fuses. It

is recommended that a qualified technician check the fuses. Use the following procedures to check
and replace fuses:

3-1

DANGER - HIGH VOLTAGE PRESENT

NEVER remove fuses from the cooker until the cooker is unplugged
from the facility power supply.

a. To check and replace heating element fuses:

1. Unplug the cooker from facility power source.

2. Remove screw to fuse access door on back panel of the cooker.

3. The heating element fuses are mounted in a fuse holder located behind the rear access
panel.

4. Remove each fuse by gently pulling the fuse straight out of the holder using a fuse
puller.

5. Use an ohmmeter set on "x 1" ohms (resistance) setting to check the fuses for
continuity. For a GOOD fuse, the meter reading should be approximately zero "0 "
ohms. If the reading is significantly above zero ohms, replace the fuse.

6. Replace each fuse by pushing the fuse straight into the fuseholder until it locks in
place.

7. Lower fuse access door.

8. Replace screw and tighten.

9. Plug the cooker into the facility power source.

3-2

3-3 REPLACEMENT PROCEDURES

These procedures are provided as a guide to removal and replacement of various cooker components.
If a test is required to verify component operation after installation, the test will be referenced.

To prevent bums, always ensure the cooker is completely SHUT DOWN and
COOLED down before performing any work.

The power supply must be disconnected before servicing or cleaning the
cooker.

33.1 Thermostat Replacement

a. Disconnect the cooker from the facility power source.

b. Open the door.

c. Drain the water from the tank.

d. Remove the front panel.

e. Disconnect the 9-pin connector.

f. Disconnect two thermostat wires from the terminal block.

g. Unscrew thermostat from tank.

h. Remove the thermostat.

i. Place sealant on the new thermostat.

j. Install new thermostat in the tank.

k. Reconnect thermostat wires to the terminal block.

1. Reconnect the 9-pin connector.

3-3

m.Reinstall the front panel.

Remove the two mounting screws from the limit control bracket and remove the limit

n. Close drain.

o. Close the door.

p. Reconnect the cooker to the facility power source.

3.3.2 Limit Control Replacement

The limit control includes a temperature sensor inside the tank, a control unit inside the cooker

cabinet, and connecting capillary tubing.

The limit control capillary tubing is very delicate. Be VERY CAREFUL when
working with the capillary tubing. The limit control is no longer usable if the tubing

is kinked or broken.

a. Disconnect the cooker from the facility power source.

CAUTION

b. Drain the water from the cooker and remove the element rack assembly.

c. The limit control probe (heat sensor) is clamped to the heating element inside the tank.

Unscrew and remove the two screws in the probe clamp.

d. Remove the probe from the clamp and straighten the capillary tubing.

e. Unscrew the small hex nut inside the cabinet at the front of the tank for the limit control.

f. Unscrew the large connector nut from the tank and pull the probe and capillary tubes

through the opening.

g.

h. Install a new limit control unit by connecting the wires.

i. Place the limit control unit in the limit control bracket.

j. Install and tighten the two mounting screws.

k. Insert the probe and capillary tubes through the opening in the tank.

3-4

l. Reinstall the front panel.

NOTE

Use approved pipe joint compound on the large fitting before installing to
prevent water leakage. DO NOT use joint compound on the small nut.

m. Install the large connector nut on the tank and tighten.

n. Carefully reshape the capillary tubes.

o. Place the probe in the clamp.

p. Rescrew the two screws into the probe clamp.

q. Screw the small hex nut inside the cabinet at the front of the tank for the limit control.

r. Replace the element rack assembly.

s. Reconnect the cooker to the facility power source.

3.3.3 Heater Element Replacement

a. Disconnect the cooker from the facility power source.

b. Open the door.

c. Drain the water from the tank.

d. Remove front panel.

e. Remove the wires from the heater element.

f. Remove the element support bar.

g. Remove the limit control bulb clamp.

h. Remove two (2) nuts holding the heating elements in place.

i. Remove the heating element.

j. Place sealant on the new heating element.

k. Install the new heating element in the tank.

3-5

1. Replace the two (2) nuts and tighten them.

m.Reconnect the wires.

n. Replace the limit control bulb clamp.

o. Replace the element support bar.

p. Reinstall the front panel.

q. Reconnect the cooker to the power source.

3.4 TESTING RELAYS AND CONTACTORS
Contactors and relays use a control voltage to energize an electro magnet which closes a set of

contacts. The control voltage is applied to a solenoid type coil. When measuring a coil's resistance,
ensure the coil is disconnected from the cooker's electrical system. This will ensure that only the coil's
resistance is measured and not a part of the cooker's wiring. When measured with an Ohmmeter,
these coils should have low resistance of less than 100 ohms. Measure each of the contactors that
are suspect. If any relay or contactor coil indicates an open circuit or high amount of resistance,
replace the relay or contactor.

3.5 TESTING HEATING ELEMENTS
To test a heating element, place the POWER switch in the OFF position. Test the elements by

performi ng the following steps:

a. The terminal block that connects the heating element to the cooker is located behind the
front panel.

b. Use an ohmmeter to check the continuity of the element from one end to the other. The

reading should be very low (a few ohms). If the element indicates an open circuit, replace
the element.

c. Next check from the hot side of the element to ground. The reading should be infinite.

If it is not, replace the element.

3.6 TESTING THE THERMOSTAT

To test the thermostat, place the power switch in the OFF position. Test the thermostat by performing
the following:

a. Remove the front panel to access the thermostat wires.

3-6

b. Use an ohmmeter to measure the continuity across the thermostat wires.
c. The thermostat should be closed (0 ohms) below 195°F and open (x ohms) above

195°F.

d. If the thermostat is defective, replace it.

e. Reinstall the front panel.

f. Reconne ct the cooker to the facility power source.
