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.
