Error Codes

This section provides error codes and related information in the form of an easy-toread table. In the event of a control system failure, the control displays an error message (i.e. E-1). Also, an alarm sounds when an error code is displayed. To silence this alarm, press any button.

Display	Cause	Solution
E-1 (FPS equipped fryers only)	No oil or low oil in vat	Check to ensure oil is a proper level in vat.
E-4 CPU too hot	Control board overheating	Turn the power switch to the OFF position, and then turn the 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 obstructions. Check cooling fan, if present.
E-5 Oil too hot	Temperature probe open	Turn the power switch to the OFF position, and then turn the switch back to ON. If E-6A displays, check the temperature probe.
E-6A Oil prob open	Temperature probe shorted	Turn the power switch to the OFF position, and then turn the switch back to ON. If E-6B displays, check the temperature probe.
E-10 High limit trip	High limit PFE 500 - AA2404193 PFE 561 - AB2404002 PFG 600 - AN2404032 And after	Allow oil to cool, and then reset the high limit by manually pushing and holding the reset (red rocker) switch for 5 seconds. If the high limit does not reset, the high limit must be replaced.
E-12 (FPS equipped fryers only)	Faulty FPS probe	Turn the power switch to the OFF position, and then turn the switch back to ON. If E-12 displays, check the FPS probe.
E-15 Drain is open	Drain valve open while fryer on, or drain switch failure	Close the drain, using the drain valve handle. If E-15 displays, have the drain microswitch checked. Drain switch status can be viewed in Info Mode
E-16 Japanese SMS Controls only	Gas pressure or burner jet failure	Ensure oil level is at fill line. Ensure there is no water in the vat. Ensure the gas shut off valve is fully open and the quick disconnect is fully engaged. Ensure incoming gas pressure is at least 7 in wc for natural gas or 11 in for LP. Ensure manifold pressure is within bounds. Ensure gas connection is sized correctly. Ensure burner jet orifice is correct for gas type and altitude. Ensure burner jets are burning with a blue flame just above each jet. Verify the pilot is not sparking intermittently. Verify there is no damage to the rounded heat exchange portion of vat.
E-20C (SSI gas fryers only)	Ignition module(s) failure	Press the Timer button to try the ignition process. If the E-20C error persists, check the ignition module.
E-20D (SSI gas fryers only)	No ignition	Press the Timer button to try the ignition process. If the E-20D error persists, check the: Gas supply Gas flow Gas hose connection Gas valve
E-25 (electric fryers only)	Heats amps too high	Check the setting in SP-12 (Special Program Mode) to ensure nominal Amps is set correctly. Also, have the electrical supply, wiring and elements checked.
E-26 (electric fryers only)	Heat amps locked on	Have the contactors and PC board checked. NOTE: This error code could be displayed even with the Power switch turned to OFF. Unplug the fryer or shut off the wall circuit breaker to disconnect power to the fryer.
E-27 (electric fryers only)	Heat amps too low	Check the setting in SP-12 (Special Program Mode) to ensure nominal Amps is set correctly. Also, have the electrical supply, contactors, wiring and elements checked.
E-41	Program settings lost	Turn the power switch to the OFF position, and then turn the switch back to ON. If either E-41 or E-46 displays, try to reinitialize the control. If the error code persists, have the control board replaced.
E-46	Control memory failure
E-47	Analog converter chip or 12- Volt supply failure	Turn the power switch to the OFF position, and then turn the switch back to ON. If the E-47 error persists have the I/O board or the PC board replaced. If the speaker tones are quiet, replace the I/O board.
E-48	Input system error	Replace the PC board.
E-70A	Missing or broken wire in pins 1 and 2 of P11 connector, or faulty connector Faulty I/O board	Check the jumper wire between pins 1 and 2 . Check the I/O board and replace, if necessary.
Temp. too low for pressure	Possible water in vat.	Ensure oil is in vat and at the proper level.
E-86L	Pressure Assist error message.	Call for service.
E-92	24-VAC fuse on I/O board open (PTC self-resetting fuse)	24-VAC fuse on I/O board open: Check for shorted component in 24- volt circuit (i.e., hi limit, drain switch). Check for stuck solenoid valve, causing it to draw too much current.
