SECTION 4. TROUBLESHOOTING
4-1. TROUBLESHOOTING GUIDE
Problem Cause Correction
Power switch ON but fryer
completely inoperative
• Open Circuit
• Fryer plugged in
• Check breaker or fuse at wall
Pressure not exhausting at
end of cook cycle
Operating pressure too high
• Solenoid or Exhaust line clogged
• Deadweight clogged
• Turn OFF and allow fryer to cool to
release the pressure in frypot; have
all lines, solenoid, and exhaust tank
cleaned
• Turn OFF and allow fryer to cool to
release the pressure in frypot; clean
deadweight; see Cleaning the Dead-
weight Assembly Section
DO NOT OPERATE UNIT IF PRESSURE GAUGE SHOWS HIGH PRESSURE CONDITIONS.
SEVERE INJURIES AND BURNS WILL RESULT. IMMEDIATELY PLACE THE POWER/
PUMP SWITCH IN THE OFF POSITION, WHICH RELEASES THE PRESSURE BY ALLOWING THE UNIT TO COOL. DO NOT RESUME USE OF UNIT UNTIL CAUSE OF HIGH
PRESSURE HAS BEEN FOUND AND CORRECTED.
Pressure does not build
Shortening not heating
Foaming or boiling over
Shortening not draining
Filter motor won’t run
• Not enough product in frypot
• Metal shipping spacer not
removed from deadweight
• Faulty PC board
• Lid gasket leaking
• Gas valve knob turned to the
OFF position
• Drain valve open
• High temperature limit tripped
• See Boil-Over chart on fryer
and beginning of Operation
Section in this manual
• Drain valve clogged
• Motor overheated
• Place full capacity product in frypot
when using fresh shortening
• Remove shipping spacer; see Unpacking
Instructions Section
• Have controls checked by service
technician
• Reverse or replace lid gasket
• Make sure gas control valve knob is
turned to the ON position
• Close drain valve
• Reset high temperature limit; see Operating Controls Section
• Follow Boil-Over procedures from
chart
• Push cleaning rod through open
drain valve
• Reset motor; see Filter Pump Motor

4-2. ERROR CODES In the event of a control system failure, the digital
display will show an “Error Message.” These
messages are coded: “E4”, “E5”, “E6”, “E10”,
“E15”, “E20”, “E31”, “E41”, “E46”, “E54”, and
E-70-A & B. A constant tone is heard when an
error code is displayed, and to silence this tone,
press any button.
DISPLAY CAUSE PANEL BOARD CORRECTION
“E-4” Control board Turn switch to OFF position, then turn switch back to
overheating ON; if display shows “E-4”, the control board is getting
too hot; check the louvers on each side of the unit for
obstructions
“E-5” Shortening Turn switch to OFF position, then turn switch back to ON;
overheating if display shows “E-5”, the heating circuits and temperature
probe should be checked
“E-6 A” Temperature Turn switch to OFF position, then turn switch back to ON;
probe open if display shows “E-6”, check the temperature probe;
to replace, refer to T echnical Manual
“E-6 B” T emperature Turn switch to OFF position, then turn switch back to ON;
probe shorted if display shows “E-6” check the temperature probe;
to replace, refer to T echnical Manual
“E-10” High limit Reset the high limit by manually pushing up on the reset
button; if high limit does not reset, high limit must be
replaced; refer to T echnical Manual
“E-15” Drain switch Close drain, using the drain valve handle; if display still
failure shows “E-15”, check the drain microswitch; refer to
T echnical Manual

4-2. ERROR CODES
(Continued)
DISPLAY CAUSE PANEL BOARD CORRECTION
“E-41”, Programming Turn switch to OFF , then back to ON; if display shows any
“E-46” failure of the error codes, try to reinitialize the control (Special
Program Section) if error code persists, replace the control
board; refer to T echnical Manual
“E-20 C” Ignition modules Press the timer button to try the ignition process again; if
not responding “E-20 C” persists, check the ignition module, or the spark
ignitor, refer to Technical Manual
“E-20 D” Pilots not lit or Press the timer button to try the ignition process again; if
no flame sense “E-20 D” persists, check the ignition module, or the flame
sensor; refer to T echnical Manual
“E-31” Fan jumper wire Check for jumper wire on 12-pin connector & add if missing
missing
Control set to IDG See C1000 Special Programming Section and set controls to
instead of SSI on gas SSI in step 6
units
“E-54” PCB component Turn switch to OFF position, then turn switch back to ON;
failure if “E-54” persists, have PCB replaced
“E-70A” Fan switch jumper Have jumper wire checked on 12 pin connect to panel
missing
“E-70B” MV jumper missing Have jumper wire checked on connectors to panel
“TEMP TOO” Possible water Make sure oil is in frypot and at the proper level
LOW FOR i n frypot
