Error Codes

In the event of a system failure the control board displays an error message. These messages are coded as E which represents an error, a number designation and error message, such as E-4 CPU TO HOT. Also, a constant tone sounds. To silence the tone, press any of the product buttons. Use the following table to interpret and correct an error code.

Error

Cause

Correction

E-1 LOW OIL IN POT

The top heating element where the probe is located is getting hotter than it would if the element were submerged in oil.

If the Protection Probe monitoring function determines that the oil level is too low below the main probe it generates an E-1 error code and displays the message LOW OIL IN POT!, CHECK OIL LEVEL. Fill the vat with oil to the full line. If the error persists call for service.

E-4 CPU TOO HOT

Control board overheating.

Remove heat from the fryer, the control board is getting too hot. Once the front panel cools down the controls should return to normal operation. If the error persists call for service.

E-4 CPU TOO HOT

Control board overheating.

 Turn the switch to off position, then turn the switch back to on. if E-4 continues to display, the board is getting too hot. Check for signs of overheating behind the control panel. Once the panel cools down the controls should return to normal operation. If the E-4 error persists, replace the control.

E-5 OIL TOO HOT

Oil overheating.

Remove heat from the fryer. Once the unit cools down, the controls should return to normal operation. If the error persists call for service.

E-5 OIL TOO HOT

Oil overheating.

 Turn the switch to off position, then turn the switch back to on. If E-5 continues to display, the heating circuits and temperature probe should be checked. Once the unit cools down, the controls should return to normal operation. If the E-5 error persists, replace the control.

TRAINING: E-10 Error explanation.

E-10

High limit tripped.

Check the error log to find out the vat temperature at the time the high limit tripped. If this temperature was very low, this may be a sign that the vat was turned on with low or no oil. If this was the case, fill the pot with oil and reset the high limit. If the trip temperature was several degrees above the oil setpoint temperature, test for a sticking contactor and replace if faulty. If the high limit tripped at an oil temperature, inspect the high limit thermocouples for carbon build up and clean if necessary. If no carbon found, see 8.7 High Limit and Module Inspection, page 87and 4.6 High Limit Thermocouples Replacement, page 29. TRAINING:E-10 Error explanation.
E-10A HIGH LIMIT TRIPPED High limit tripped while vat main probe temperature was at or above 300°F. Check the error log to find out the vat temperature at the time the high limit tripped. If this was several degrees above the oil setpoint temperature, test for a sticking contactor and replace if faulty. If the trip temperature was near the oil setpoint temperature, inspect the high limit thermocouples for carbon build up and clean if necessary. If no carbon found, see 8.7 High Limit and Module Inspection, page 87and 4.6 High Limit Thermocouples Replacement, page 29.
E-10B HIGH LIMIT TRIPPED High limit tripped while vat main probe temperature was below 300°F. Check the error log to find out the vat temperature at the time the high limit tripped. If this temperature was very low, this may be a sign that the vat was turned on with low or no oil. If this was the case, fill the pot with oil and reset the high limit. If the high limit tripped at a higher temperature, inspect the high limit thermocouples for carbon build up and clean if necessary. If no carbon found, see 8.7 High Limit and Module Inspection, page 87and 4.6 High Limit Thermocouples Replacement, page 29.
E-10C HIGH LIMIT TRIPPED High limit tripped while cooking (Not simply in cook mode, but with cook cycle running). Check the error log to find out the vat temperature at the time the high limit tripped. If this was several degrees above the oil setpoint temperature, test for a sticking contactor and replace if faulty. If the trip temperature was near the oil setpoint temperature, inspect the high limit thermocouples for carbon build up and clean if necessary. If no carbon found, see 8.7 High Limit and Module Inspection, page 87and 4.6 High Limit Thermocouples Replacement, page 29.
E-10D HIGH LIMIT TRIPPED High limit tripped less than 5 minutes after fryer was performing an Auto-Filter or Quick Filter and the control returned to cook mode on its own after detecting that the oil was pumped up (based on temperature rise on level probe). Check the error log to find out the vat temperature at the time the high limit tripped. If this was several degrees above the oil setpoint temperature, test for a sticking contactor and replace if faulty. If the trip temperature was near the oil setpoint temperature, inspect the high limit thermocouples for carbon build up and clean if necessary. If no carbon found, see 8.7 High Limit and Module Inspection, page 87and 4.6 High Limit Thermocouples Replacement, page 29.

Check the error log to find out the vat temperature at the time the high limit tripped. If this was several degrees above the oil setpoint temperature, test for a sticking contactor and replace if faulty. If the trip temperature was near the oil setpoint temperature, inspect the high limit thermocouples for carbon build up and clean if necessary. If no carbon found, see 8.7 High Limit and Module Inspection, page 87and 4.6 High Limit Thermocouples Replacement, page 29.
E-10M HIGH LIMIT TRIPPED High limit tripped while fryer was in Melt Mode. Check the error log to find out the vat temperature at the time the high limit tripped. If this temperature was very low, this may be a sign that the vat was turned on with low or no oil. If this was the case, fill the pot with oil and reset the high limit. If the high limit tripped at a higher temperature, inspect the high limit thermocouples for carbon build up and clean if necessary. If no carbon found, see 8.7 High Limit and Module Inspection, page 87and 4.6 High Limit Thermocouples Replacement, page 29.
E-10S HIGH LIMIT TRIPPED High limit tripped while vat was in Start-up Mode (not including Melt mode), but not while it was executing one of the filter operations. Check the error log to find out the vat temperature at the time the high limit tripped. If this temperature was very low, this may be a sign that the vat was turned on with low or no oil. If this was the case, fill the pot with oil and reset the high limit. If the high limit tripped at a higher temperature, inspect the high limit thermocouples for carbon build up and clean if necessary. If no carbon found, see 8.7 High Limit and Module Inspection, page 87and 4.6 High Limit Thermocouples Replacement, page 29.
E-10Y HIGH LIMIT TRIPPED High limit tripped less than 5 minutes after user responded YES to, Is Pot Filled? question.

If this was the case, fill the pot with oil and reset the high limit. If the high limit tripped at a higher temperature, inspect the high limit thermocouples for carbon build up and clean if necessary. If no carbon found, see 8.7 High Limit and Module Inspection, page 87and 4.6 High Limit Thermocouples Replacement, page 29.
E-13A PRESSURE SENSOR FAILED Sensor failed or unplugged

A “good” reading from the sensor is between 0.5v (0 PSI) and 4.5v (30 PSI). Tolerances beyond those values are allowed: - Low reference value less than 0.25v - The “unplugged” condition should generate an E- 13A. A pull-down resistor on the CPU board pulls the input low if disconnected.

Any E-13 error allows operators to cook on the fryer; however, the control disables the pressure for the entire cook cycle unless the E-13 condition resolves with a good probe readings.

E-13B PRESSURE SENSOR FAILED

Sensor failed or shorted to +5v

A “good” reading from the sensor is between 0.5v (0 PSI) and 4.5v (30 PSI). Tolerances beyond those values are allowed: - High reference value more than 4.75v

Any E-13 error allows operators to cook on the fryer; however, the control disables the pressure for the entire cook cycle unless the E-13 condition resolves with a good probe readings.
E-14 PRESSURE TOO HIGH Pressure is to high within the vat.

Check deadweight chamber for any obstruction.

Check the steam exhaust passage for obstruction.

E-15C DRAIN VALVE ERROR

The drain valve doesn't fully closed.

Unclog the drain with a drain brush. If the error persists call for service.

E-15C DRAIN VALVE ERROR

The control energized the drain valve to close it, and waited a reasonable amount of time, but didn’t see the expected feedback signal that would have confirmed that the drain valve was fully closed.

Check the drain valve for obstruction. Carefully remove any obstruction found. If no obstruction, check to make sure both connections to the drain valve are plugged in securely. If connections are secure, operate the drain valve using the drain valve test in tech mode. If no drain valve movement, test to make sure the drain valve is getting 24 VDC from control board when testing both directions (open and closed) from connector P9 pins 3 & 4. If voltage is present and no movement, replace drain valve motor. If no DC voltage, replace control board.

E-15P DRAIN VALVE ERROR

The drain valve doesn't fully open.

Check drain for an obstruction. If the error persists call for service.
E-15P DRAIN VALVE ERROR The control energized the drain valve to open it, and waited a reasonable amount of time, but didn’t see the expected feedback. signal that would have confirmed that the drain valve was fully open.

E-19 PROTECTION PROBE FAILED

Call for service.
E-19 PROTECTION PROBE FAILED A setting in Tech Mode (T-40) specifies whether or not the fryer is equipped with a protection probe system. If the T-40 option is set to YES, and the control does not detect a valid reading on the protection probe input, an E-19 error is generated. Replace the protection probe. Once the error code is acknowledged, the E-19 message goes away and normal operation resumes without the benefit of the protection probe feature. If the protection probe input is in a continuously failed state, the E-19 error repeats every 4 hours. If this E-19 error occurs in a fryer that does not have and is not supposed to have a protection probe installed, access Tech Mode and change the T- 40 option to NO.
