Error Codes

The controls monitor procedure problems and system failures with warnings and error codes. The warning or error code displays, and an alarm sounds. Pressing Product button 2 cancels most warnings and pressing any control button stops most Error Code alarms. But there are some exceptions (see below). The error displays until the situation is corrected.

Display Cause Solution

“W-1” “LOW VOLTAGE”

Incoming supply voltage too low

Have voltage at plug and receptacle checked.

“W-2” “SLOW HEATUP”

Faulty components or connections

Have elements, connections, and contactors checked.

“W-3” “WAS NOT READY”

Product loaded into vat before Ready lights illuminate

Wait until peanut oil is at proper temperature before loading product.
“W-4” “SLOW COOKING” Frozen or too much product in vat Do not overfill or place frozen product into the vat.
“W-5” “SLOW COOKING”

Product loaded into vat before Ready lights illuminate

 Wait until peanut oil is at proper temperature before loading product.

“W-6”

“SLOW

COOKING”

Faulty components or connections

Have elements, connections, and contactors checked.
“W-7” “LOW AMPS”

Faulty components or connections

 Have elements, connections, and contactors checked.
“W-9” “DISCARD PRODUCT” Product overcooked (may appear after a “W-6”, “SLOW COOKING” warning) Discard product immediately.
“OIL TOO HOT” Didn’t allow peanut oil to drop down to current product’s setpoint CANCEL button will not stop this warning. Wait until the peanut oil temperature drops to set point temperature, the alarm automatically stops.
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-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-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-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.
E-70B

  • Faulty COOK/PUMP switch or switch wiring

  • faulty I/O board

  • Have COOKPUMP switch checked, along with its wiring

  • Have I/O board checked
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.
