4.01.13.1 Resolving Controller Errors
&
Alarms
NOTE: If an error condition persist and cannot be resolved, it could be an indication of component failure or
system malfunction. Please contact a factory ‐ authorized service agent, or call 800.554.4537 for Giles Technical
Support.
●
DRAIN OPEN (Error Code OPEN) ‐ If the vat drain valve is open (even slightly) while fryer power is ON, an alarm
sounds, Lower Display shows “OPEn” , and the Upper Display reads “ERROR ALARM ‐ DRAIN IS OPEN” . If a
basket lift is down, it is raised. Heating elements are shutdown as long as the condition exists.
Press the [ALARM] key to silence alarm. Completely close the drain valve. When error clears, alarm sounds
again and the Upper Display reads “CHECK OIL LEVEL, ENSURE VAT IS FULL, IF FULL THEN PRESS [START]” . This
is a post ‐ error alarm to alert user to confirm that cooking oil in the vat is at the [FULL] level. Add oil if needed,
then press the [START] key to return to PREHEAT .
●
LOW OIL LEVEL (Error Code 03) ‐ Alarm sounds, Lower Display shows “Er03” , and the Upper Display reads
“ERROR ALARM ‐ CHECK OIL LEVEL ‐ ENSURE VAT IS FULL” . Heating elements are shutdown until the condition
is corrected. The temperature differential between a sensor located at the [ADD] oil mark and one attached to
the heating element exceeds an acceptable value, indicating a low oil level. Low oil level greatly increases the
possibility of fire! Press the [ALARM] key to silence alarm and place Heat Switch in the [OFF] position. Allow
the oil to adequately cool and then add oil to raise level to the [FULL] mark.
●
LOW OIL LEVEL Post ‐ error Warning (Error Code 06) ‐ After Error 03 clears, another alarm sounds. The Lower
Display shows “ Er06” , and the Upper Display reads “CHECK OIL LEVEL ‐ ENSURE VAT IS FULL ‐ PRESS [START]” .
This alarm alerts user to confirm that cooking oil in the vat is at the [FULL] level. If no oil is required press
[START] , otherwise press [ALARM] key to silence alarm, add oil, then press [START] key to enter PREHEAT .
●
MAX. ELEMENT TEMP (Error Code 19) ‐ Heating element has exceeded the maximum temperature allowed by
the controller. The alarm sounds, Lower Display shows “Er19” , and the Upper Display shows “ERROR ALARM ‐
MAX ELEMENT TEMPERATURE” . Heating element is automatically shutdown and must cool to an acceptable
temperature to clear the error. Typical cause of this error is low oil level, which has exposed the heating
element. It is possible for a false alarm to occur when preheating cold oil at the initial startup of a new day.
Vigorously stirring oil during preheat will usually prevent, or clear, a false alarm of this type.
●
MAX ELEMENT TEMP Post ‐ error Warning (Error Code 07) ‐ After Error 19 is cleared, another alarm sounds.
The Lower Display shows “Er07” , and the Upper Display reads “MAX ELEMENT TEMP ‐ PRESS [START]” . This
alarm alerts user that a maximum element temperature error occurred and is now cleared. Press [START] key
to enter PREHEAT . The heating elements will not turn ON until the [START] key is pressed.
