The kettle's water level must be maintained at the
proper level to submerge the heater elements.
Under normal operating conditions, the sealed
water reservoir should never require the addition
of water.
If the red "low water" light comes on during use
(while the kettle is in an upright position), the
water level has reached a critically low level. The
low water protection control has automatically shut
off the heater elements. The following procedure
must be completed before further use:
NOTE: Have a qualified service technician repair
the leakage problem and add water to the unit.
Ensure that the red "low water" light is on when the
kettle is upright. On tilting kettles, it is normal for
the red light to come on when the kettle is in a
tilted position, as the elements are not submerged
in water at this point.
CAUTION: Only a mixture of distilled water and
rust inhibitor should be used when adding water
to a partially filled water reservoir. Local tap water
conditions may cause kettle damage which is not
covered under warranty. Rust inhibitor is
purchased locally. Read directions and do not
exceed manufacturer's recommendation
(excessive rust inhibitor can also cause
solidification).

box. While kettle is cold or thermistor is
removed and allowed to cool, measure
the resistance between edge connector’s
pins #2 and #7. Is it approximately
100,00 ohms?
B/ Problem: Kettle heats too slowly or not hot enough. (Note: normal max. operating pressure with an
empty kettle is 30-35 psi.)
YesGo to step #11.
NoReplace defective potentiometer.
YesSpray contact cleaner on control box
terminals and edge connector. Try box
again, if the problem still exists, replace
defective control box.
NoReplace defective thermistor.
Possible Causes
1.Air in jacket requires
venting.
2.Defective safety thermostat.
3.Defective potentiometer.
4.Defective thermistor.
5.Defective contactor/s.
6.Defective control box.
7.Defective elements/s.
Fault Isolation Pr
ocedure
StepTest
1.In a cold state, does the pressure gauge
read in the green zone?
2.Do the contactors shut off too early?
(before reaching normal maximum
operating pressure.)
3.Does the green LED remain illuminated
after the contactors shut off?
4.Unplug control box and measure the
resistance across potentiometer. Is it
approximately 0 ohms at maximum and
50,000 ohms at minimum setting?
ResultRemedy
YesGo to step #2.
NoThere is air present in the jacket of the
kettle. Follow Kettle Venting Procedure
(page 12). If constant venting is required,
there is a leak that should be corrected.
YesGo to step #3.
NoCheck contactor contacts for pitting.
Voltage across terminal of contactor
while energized signifies a poor
contact. Replace contactor/s as
necessary. Check elements for short to
ground or open circuit. If elements are
defective, contact the factory. Elements
are not field replaceable.
YesReplace defective safety thermostat.
NoGo to step #4.
YesGo to step #5.
NoReplace defective thermistor..
YesGo to step #6.

5.Remove kettle thermistor and allow to
cool. Remove edge connector from
control box. Test resistance across edge
connector's pins #2 and #7. Is it
approximately 100,000 ohms?
NoReplace defective thermistor
6.Turn the potentiometer on the control box
clockwise to increase the maximum
operating temperature. Does the kettle
now achieve maximum operating
pressure of 30-35 psi in an empty kettle?
C/ Problem: Kettle is overheating.
Possible Causes
1.Defective thermistor
2.Defective potentiometer.
Fault Isolation Pr
ocedure
3.Defective 12 VDC relay.
4.Defective control box.
StepTest
1.Does the green LED turn off even though
the contactors remain energized?
2.Unplug the control box and measure the
resistance across the potentiometer, Is the
resistance approximately 0 ohms at maximum
and 50,000 ohms at minimum setting?
YesKettle is operating correctly.
NoSpray contact cleaner on control
terminals and edge connector. Try box
again. If problem still exists, replace
defective control box.
ResultRemedy
YesReplace defective 12 VDC relay.
NoGo to step #2.
YesGo to step #3.
NoReplace defective thermistor.
3.Remove kettle thermistor and allow to cool
Remove edge connector from control box.
Test resistance across edge connector’s
pins #2 and #7. Is it approximately 100,000
ohms?
4.Turn the potentiometer on the control box
counter-clockwise to decrease the
maximum operating temperature. does the
kettle continue to overheat?
D/ Problem: Red LED remains illuminated even though water has been added.
YesGo to step #4.
NoReplace defective thermistor.
Yes
