V SERVICE DIAGNOSIS
THE COOKER MUST BE DISCONNECTED FROM
ITS POWER SOURCE OR SHUT DOWN AT THE
BREAKER PRIOR TO SERVICE.
AUTO-FILL SYSTEM
The auto-fill system allows the automatic addition of
water to the pasta cooker during cooking or idle
function. The system is controlled by the on/off switch
explained in CLEANING. If the system should fail to
allow the pasta cooker to fill with water, check the power
supply to the pasta cooker. If the left side amber
indicating light is not on, check the circuit breaker to the
cooker. If the pasta cooker fails to stop adding water or
fails to turn the elements off, check the water level
sensors. Clean the sensors as stated in PREVENTIVE
MAINTENANCE. If after cleaning, the system still fails it
is possible to adjust the control boards inside the field
wire box.
THIS ADJUSTMENT IS DONE PRIOR TO SHIPMENT
AT THE FACTORY. IT SHOULD ONLY BE ADJUSTED
BY A QUALIFIED SERVICE TECHNICIAN.
The potentionmeter is located on the control board. It is
a black knob with a white triangle imprinted on it. The
potentionmeter adjusts the sensitivity of the probe.
Adjusting this sensor will not increase the depth of the
water. Improper adjustments can effect the operation of
the cooker and cause damage. All boards returned to
Keating are tested. The board marked with a “B” is the
top water level or fill board. The board marked with an
“A” is the safety or low level board. The “A” board is
connected to the bottom sensor and turns the elements
off when the water falls below the level of sensor. The
“B” board is connected to the top sensor and adds water
when the level falls below the probe.
Regular cleaning
of these sensors is of the utmost importance.
COOKER HEATING SECTION
The heating section as explained in CONTROL
FEATURES is not that of a fryer. The thermostats
control the heat only to one element except during
heavy use. If the cooker boils over, check the
thermostat setting and calibration. Remember a boil
over is not covered under warranty and the pasta
cooker should never be left unattended. When the
ON/OFF switch on the left side is turned to the ON
position, you will hear one of three contactors click in.
As the thermostats turn the elements on and off, other
contactors will also be heard. Refer to wiring diagram.
