Error Codes

In the event of a control system failure, the digital an error message displays. The message codes are shown in the DISPLAY column below. A constant tone is heard when an error code displays, and to silence this tone, press any button.

Display	Cause	Correction
“E-4”	Control board overheating.	Turn switch to OFF position, then turn switch back to ON; if “E-4” displays, the control board is getting too hot; check the louvers on each side of the unit for obstruction.
“E-5”	Oil overheating.	Turn switch to OFF position, then back to ON; if “E-5” displays, the heating circuits and temperature probe should be checked.
“E-6A”	Temperature probe open.	Turn switch to OFF position, then back to ON; if “E-6” displays, the temperature probe should be checked.
“E-6B”	Temperature probe shorted.
“E-10” "E-10 A" "E-10 B" "E-10 C" "E-10 D" "E-10 F" "E-10 M" "E-10 Y"	High limit High limit tripped above 300° F High limit tripped below 300° F High limit tripped while cooking High limit tripped less than 5 minutes of Auto Filter High limit tripped during filter cycle High limit tripped during melt mode High limit tripped less than 5 minutes of "YES"	Let the unit cool down (15-20 minutes). Locate the high limit reset under the control. Press the high limit reset button.
“E-15”	Drain switch.	Ensure drain knob is completely pushed-in; if E-15 per- sists, have drain switch checked.
“E-18A”	Left level sensor open.	Turn switch to OFF position, then back to ON; if display still indicates a failed sensor, have the connections checked on the control board. Have sensor check and replaced if necessary.
“E-18B”	Right level sensor open.
“E-18C”	Both level sensors open.
“E-20A” “FAN SENSOR STUCK CLOSED”	Pressure switch failure.	If fan is not running, have pressure switch checked; should be open circuit if no air pressure.
	Wiring problem.	If fan is running, wiring error, or relay on I/O board closed
	I/O board failure.
“E-20B” “NO DRAFT” “CHECK FAN”	Pressure switch failure/hose loose.	Press power button to vat off and back on again, if E-20-B persists, have pressure switch checked; should be open circuit if no air pressure; ensure hose is connected to fan and pressure switch.
	Draft fan failure/ low voltage.	Have draft fan checked; low voltage going to fan.
	Flue or hood obstruction.	Check the fryer flue and hood system for obstructions.
“E-20D" “IGNITION FAILURE”	Failure to ignite/ no flame sense.	Press power button to vat off and back on again, if E-20-D persists, check gas line connections; check gas shut-off valve; have ignition module checked; gas valve checked; flame sensor gap checked; gas valve and ignition module wiring checked.
“E-20D" “IGNITION FAILURE”	Plugged atmospheric equalization hole in regulator cap resulting in pilot flame slowly fading.	Clear obstruction from hole.
“E-21”	Slow heat recovery.	Have a certified service technician check the fryer for cor- rect voltage to the unit; have heat circuit checked; have unit checked for loose or burnt wires.
“E-22” ”NO HEAT” ”CHECK GAS VALVE”	Burner not igniting.	Have gas valve and heat circuit checked.
“E-41” ”E-46”	Programming failure.	Turn power switch to OFF, then back to ON; if an error code displays, have the controls re-initialized; if error code persists, have the control board replaced.
“E-47”	Analog converter chip or 12-volt supply failure.	Turn power switch OFF, then back to ON; if “E-47” per- sists, have the I/O board, or the PC board replaced; if speaker tones are quiet, probably I/O board failure; have the I/O board replaced.
“E-48”	Input system error.	Have PC board replaced.
“E-54C”	Temperature input error.	Turn power switch to OFF, then back to ON; have control PC board replaced if “E-54C” persists.
“E-60” “FILTER IN USE”	AIF PC board not communicating with PC board.	Turn power switch to OFF, wait 15 seconds, then turn switch back to ON. If “E-60 persists, have connector be- tween the PC boards checked; replace AIF PC board or control PC board if necessary.
“E-70C”	Drain valve jumper wire missing or disconnected.	Have the jumper wire checked on the PC board at drain switch interlock position.
"E-82 D"	Selector valve failed	No activity is detected. Check motor encoder, selector valve motor, and AIF board.
“E-93” ”24 VDC SUPPLY TRIPPED”	Autolift motor malfunction or failure.	If AutoLift feature is not operating, have each of the Auto- lift motors checked. Check the 24V circuits.
