5.01.11.1 Resolving Controller Errors and Alarms
• DRAIN OPEN (Error Code OPEN) - If the pot Drain Valve is open (even slightly) while Fryer power is ON, an alarm
tone sounds, Lower 7-Segment Display shows “OPEn” , the Upper OLED Display reads “ERROR ALARM - DRAIN IS
OPEN”, power to the Heating Elements is shutdown. Elements are disabled as long as the error exists.
Press the [ALARM] key to silence alarm tone. Completely close the Drain Valve to clear the error. When error is
cleared, alarm tone sounds again and the Upper OLED 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 pot is still at
the [FULL] level. Add oil if needed, then press the [START] key to return to PREHEAT mode.
• MAX. ELEMENT TEMP (Error Code 19) - Heating Element has exceeded the maximum temperature allowed by
the Controller. The alarm tone sounds, Lower Display shows “Er19” , the Upper Display shows “ERROR ALARM -
MAX ELEMENT TEMPERATURE” , and power to Heating Elements is shutdown. Elements 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 false alarms 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, a warning alarm occurs. 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 mode. Heating Elements will not turn ON until [START] is pressed.
• BAFFLE FILTER MISSING (Error Code 21) - Alarm tone sounds, Lower Display shows “Er21” , and the Upper
Display reads “ERROR ALARM - BAFFLE FILTER MISSING” . Indicates that the Baffle Filter is missing or improperly
installed. Heating Elements are disabled until the condition is corrected. Install the Baffle Filter, or adjust its
position; error will clear when Filter is properly installed. See Section 7.1.2. & 7.1.3, Baffle Filter Removal &
Installation .
• CHARCOAL FILTER MISSING (Error Code 22) - Alarm tone sounds, Lower Display shows “Er22” , and the Upper
Display reads “ERROR ALARM - CHARCOAL FILTER MISSING” . Indicates that the Charcoal Filter is missing or
improperly installed. Heating Elements are disabled until the condition is corrected. Install the Charcoal Filter, or
adjust its position; error will clear when Filter is properly installed. See Section 7.1.10, Charcoal Filter
Installation .
• CLOGGED FILTER (Error Code 23) - Alarm tone sounds, Lower Display shows “Er23” , and the Upper Display
reads “ERROR ALARM - CLOGGED FILTER” . Indicates that the internal pressure switch has failed to engage. This
is typically due to insufficient airflow through the Hood and usually means that the Charcoal Filter is clogged and
needs to be replaced . Other airflow restricting conditions will also cause the alarm. Heating Elements are
disabled until the condition is corrected. Install a NEW Charcoal Filter and/or check for any other airflow
restrictions; the error will clear when proper airflow is restored. See Section 7.1.10 & 7.1.12, Charcoal Filter
Installation & Replacement .
• E.A.C. DIRTY (Error Code 24) - Alarm tone sounds, Lower Display shows “Er24” , and the Upper Display reads
“ERROR ALARM - CLEAN THE EAC” . Indicates that the Electronic Air Cleaner (EAC) Cell is excessively dirty,
missing, improperly installed, damaged, or has stopped functioning due to malfunction. Heating Elements are
disabled until the condition is corrected. Clean/check the EAC Cell; the error will clear when the condition is
resolved. See Section 7.1.6 through 7.1.9, EAC Filter Operation & Cleaning
