4.01.11 Controller Errors & Alarms
ERROR CODE DESCRIPTION (OLED Display) PROBLEM
OPEN DRAIN IS OPEN
Drain valve is open, or not completely closed. If equipped
w/basket lift, basket will be raised if it is down.
‐‐‐‐
CHECK OIL LEVEL, ENSURE VAT IS
FULL, IF FULL THEN PRESS
[START]
This is a secondary prompt to confirm oil level, which is
displayed after an OPEN drain error is cleared.
ER03
LOW OIL LEVEL – ENSURE VAT IS
FULL (Element/Add Level
Differential Warning)
The oil level is below the [ADD] line in the vat. Add fresh oil
until level is at [FULL] mark & stir. Error remains in effect until
temperature differential is cleared.
ER06
LOW OIL LEVEL – ENSURE VAT IS
FULL – PRESS [START]
(Post ER03 Warning)
This is a secondary prompt to confirm oil level, which is
displayed after LOW OIL ER03 error is cleared .
ER07
MAX ELEMENT TEMP – PRESS
[START] (Post Warning)
This is a secondary prompt displayed after MAX ELEMENT TEMP
ER19 error is cleared (element has cooled sufficiently).
ER13 OIL PROBE Error Problem with the variable oil temp sensor. Service required.
ER15 ELEMENT PROBE Error
Problem with the element temp sensor, typically attached
directly to heating element. Service required.
ER17 ADD LEVEL PROBE Error
Problem with the “Add Level” sensor located at vat “ADD” mark.
Fryer without this sensor must have the ELMT‐ADD DIFF ENABLE
setting OFF in Factory Settings. Sensor cannot be bypassed.
Service required.
ER19 MAX ELEMENT TEMP Error
The maximum heating element temperature has been exceeded.
This is a safety device; NEVER bypass this Probe.
ER25 GUARD BAND EXCEEDED
Actual oil temperature deviates from setpoint by the Guard
Band value. Allow oil to cool or heat to be within range. Factory
default is 900°F ... Typically, this error should not occur.
ER37 EEPROM Error
An error occurred while saving settings to the EEPROM. Contact
Giles Tech Service (800.554.4537).
ER38 Internal ADC Error
The ADC (Analog‐to‐Digital Converter) chip that reads output
from thermocouples is not working. MCB1 board must be
replaced. Contact Giles Tech Service (800.554.4537).
Conditions which can cause unsafe operation or damage to the unit (open valves, low oil
level, max high temp, etc.) cause the controller to halt operation, sound an alarm tone
and issue error codes/messages. Error codes are shown on the
Lower 7‐Segment Display; error messages and prompts are shown
on the Upper OLED Display. Generally, heating elements are
disabled until error conditions have been corrected. Pressing the
[ALARM] key silences the alarm tone, but does not clear an error.
Error codes are explained in the table below; details as to resolution
of errors are discussed in Section 4.01.11.1.
