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

“W-9” “DISCARD PRODUCT” Product overcooked (may appear after a “W-6”, “SLOW COOKING” warning) Discard product immediately.
“OIL TOO HOT” Tried to cook before peanut oil temperature lowers to current product’s setpoint

CANCEL button will not stop this warning. This is for your safety.

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 persists, the control board is getting too hot:

  • Check the louvers on each side of the unit for obstructions. Clean if obstructed.

  • Check if cooling fan, if present, is moving. If not call for service
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 persists, call service.
E-6A Oil probe open Temperature probe shorted Turn the power switch to the OFF position, and then turn the switch back to ON. If E-6B persists, calls for service.

Allow oil to cool, and then reset the high limit by manually pushing up on the reset button. If the high limit does not reset, the high limit must be replaced.
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-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.

If problem persists, call for service.
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, call for service.

E-20D

(SSI gas
