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.

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.
