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

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-20A (Gas fryer only) Air pressure switch failure (stuck closed) Press the Timer button to try the ignition process. If the E-20A error persists, check the air switch.
E-20B (Gas fryer only) Draft fan or air pressure switch failure (stuck open) Press the Timer button to try the ignition process. If the E-20B error persists, check the air switch or the blower motor.
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.
