Anets Fryer Code LoC: Program Mode Locked
LoC on an Anets AGP fryer with the digital controller means program mode is password protected. It is an information message, not a problem. Enter the password, or wait for the controller to leave program mode.
Low: an information message about password protection; the fryer is not reporting a breakdown.
What does Anets error code LoC mean?
LoC is short for locked. The digital controller keeps its programming settings behind a password so that cooking settings cannot be changed by accident. When someone enters program mode without the password, the display shows LoC to say the settings are protected. The manual, in the digital controller table on page 30, describes it as program mode being password protected, and the action is to enter the password or to wait until the controller exits program mode by itself. It is not a probe, burner or ignition message, and the fryer is not reporting a breakdown. The manual does not give the password or say how long the controller waits before leaving program mode. Our reading is that LoC appears when programming is attempted, so it should disappear once the controller returns to normal cooking display.
Affected models and control systems
Anets AGP series gas fryers (AGP55, AGP55T, AGP60, AGP60W and AGP75) with the digital controller, where the manual shows the message as LoC.
Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.
What you may notice
- LoC shows on the display after the program keys are pressed
- Settings cannot be changed
- Normal cooking and heating are otherwise unaffected
Possible causes
Likely causes — what usually sits behind error code LoC on this control. A technician confirms which one it is before any part is replaced.
- Program mode is password protected and was entered without the password
- Someone pressed the program keys by accident while cleaning or working near the controller
- Controller left in program mode, so LoC returns the next time the keys are touched
Safe checks before calling for service
- Do not press the program keys again. Wait for the controller to leave program mode, which the manual says it does by itself.
- If you have the password and need to change a setting, enter it as your manager directs.
- Check that the display has returned to the normal temperature display before cooking.
- If LoC will not go away and the fryer will not show a temperature, note what you pressed and tell the service call.
How a technician diagnoses error code LoC
- Confirm the message is LoC and not a probe or ignition message.
- Ask who last used program mode and whether the password was changed.
- Check the keypad for sticking keys or grease that could cause unwanted key presses.
- Check the display returns to normal and the fryer heats to the setpoint.
- Reset or reload settings only with the owner's authority and the correct password.
- Changing settings behind the password can alter cooking temperatures and safety limits, and should be done by someone responsible for them.
- If a keypad is sticking, cleaning inside the control housing involves wiring near the burner circuit.
How error code LoC differs from similar codes
LoC is an information message on the digital controller. It is unlike Prob, HI or HEAT FAIL, which are reports of probe, temperature or ignition problems.

Is LoC a problem with the fryer?
No. The manual lists it as program mode being password protected.
How do I get rid of it?
