Error Messages

The following is a list of error codes from the F5. Errors marked as critical errors indicate a situation that requires immediate attention. To resolve an error, perform all of the corrective action steps until the error is resolved. If after performing all of the corrective action steps the error still remains, contact technical support for assistance.

Error Code	Possible Cause	Corrective Action
“E-4” ”Fryer control overheat”	A source of heat is too close to the fryer. The cooling fan within the control assembly is not functioning.	Either move the source of heat away from the fryer, or move the fryer away from the source of heat. VIU display board overheating, reset control. Contact technical support for assistance.
“E-5” ”Oil overheat” The oil in the vat has reached temperatures at or above 400° F (204°C)	If the actual temperature of oil is too hot, the temperature sensor may be covered with breading or food product. Excessive carbon build up exists on the temperature sensor because a deep clean has not been performed in the last 3 months.	Clean debris off of the temperature sensor inside the vat. Perform a deep clean procedure. This helps loosen debris that may have formed around the temperature probes.
“E-6” ”Cannot read temperature"	The temperature sensor is damaged or disconnected. NOTICE: Sensors can be damaged if struck with baskets or other hard objects. Use brushes only when cleaning sensors in the vat.	Contact technical support for assistance.
“E-10” ”Safety sensor overheat” The fryer high limit safety sensor overheated and tripped.	If express filters are repeatedly skipped, the safety sensor becomes covered with crumbs causing it to overheat. If the vat has no oil, or the oil level is below the temperature sensor, the safety sensor will overheat. If the deep clean has not been performed in the last 3 months, carbon will build up and insulate the safety sensor causing it to overheat.	Allow 15 minutes for the vat to cool. Filter to remove crumbs from the bottom of the vat. Reset the high limit and ensure express filters are performed when prompted. Ensure the vat is filled with oil, then reset the high limit. Reset the high limit then perform a deep clean on the vat.
"E-15" "Drain Valve Closed"	Something is preventing the drain valve from opening.	Try draining oil from the vat and refilling or filtering and if the valve doesn't open, contact technical support for assistance.
“E-18” ”Level Sensor Failure”	The level sensor is either damaged or has come disconnected. NOTICE: Sensors can be damaged if struck with baskets or other hard objects. Use brushes only when cleaning sensors in the vat.	Contact technical support for assistance
“E-21” ”Oil heating failure” The vat is heating the oil too slowly. Cooking is still possible.	WARNING! Heating capacity for this vat may be reduced and product may be undercooked. Always check product temperature before serving or severe illness may result.
	The power cord is not pushed all of the way into the receptacle. Low voltage, or voltage issue at the receptacle.	Ensure that each power cord of the fryer is pushed in all the way. Contact a certified electrician to troubleshoot issues with the receptacle, breaker, or supply voltage.
“E-22” ”Check power supply “ Vat not heating.	The power cord for the vat is not plugged in / not pushed in all the way. The breaker is tripped. No voltage at receptacle.	Ensure that each power cord of the fryer is plugged in and pushed in all the way. Reset the circuit breaker. For two, three and four vat units, perform a quick check by switching plugs with another working vat. If the vat now starts to heat, then the original receptacle had no voltage. Contact a certified electrician to troubleshoot issues with the receptacle, breaker, or supply voltage. If after switching the plugs, the vat still does not heat, contact Henny Penny technical support for assistance.
“E-31” ”Heating Elements Up”	Crumb build up is not allowing the heating element to fully lower. The heater wasn’t pushed down all of the way after the daily filter.	Perform an express filter and remove the excess crumb build up under the heater. Use a fryer basket to gently push down on the heating element.
“E-41” ”Controller data loss"	Programming failure.	Turn main power switch off and back on again. if error code persists, contact technical support for assistance.
“E-46” ”Memory write failure”	Programming failure.	Turn main power switch off and back on again. if error code persists, contact technical support for assistance.
“E-47” ”A to D failure”	Internal control failure.	Turn main power switch off and back on again. if error code persists, contact technical support for assistance.
“E-48” ”Controller input failure”	Input system failure.	Turn main power switch off and back on again. if error code persists, contact technical support for assistance.
“E-60” ”Filtration board communication” Fryer still heats, however no filtration or top off is performed.	AIF board, power supply or communication failure.	Turn main power switch off and back on again. if error code persists, contact technical support for assistance.
“E-70C” ”Drain interlock failure” Filtration cannot be performed.	Communication with the drain valve has failed.	Contact technical support for assistance.
“E-82” ”Selector valve failed” Filtration and auto top off of vats cannot be performed.	No response from the selector valve.	Turn main power switch off and back on again. if error code persists, contact technical support for assistance.
"E-93A” ”Supply tripped"	Power supply failed.	Contact technical support for assistance.
