Anets Fryer Codes drn, turn, OFF: Drain Valve Open

What does Anets error code Drn / turn / OFF mean?

This message appears in three parts, drn, then turn, then OFF, and reads as a sentence: drain, turn off. The digital controller watches the drain valve, and if the valve is open while the controller is switched on it refuses to carry on and shows the sequence. The reason is plain: with the drain open, oil would run out of the vat, and a burner firing into an empty or draining vat is a hazard. The manual gives the meaning, drain valve open while the controller is on, and the action, which is to turn the fryer off and close the drain valve before turning it on again. It lists no other causes. The computer control form of the same condition reads DRAINING and TURN OFF, and our earlier wording came from that version, while the digital controller shows the three short words in sequence.

Affected models and control systems

Anets AGP series gas fryers (AGP55, AGP55T, AGP60, AGP60W and AGP75) with the digital controller, which cycles through drn, turn and OFF. It is the digital controller form of a code that also exists on the computer control.

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

• The display steps through drn, turn and OFF one after another
• The burner will not light and the fryer does not heat
• The drain handle is not fully in the closed position

Possible causes

Likely causes — what usually sits behind error code Drn / turn / OFF on this control. A technician confirms which one it is before any part is replaced.

• Drain handle left partly open after filtering or cleaning the vat
• Handle closed but not seating against the switch that tells the controller the valve is shut
• Crusted oil keeping the drain valve from closing all the way

Safe checks before calling for service

How a technician diagnoses error code Drn / turn / OFF

1. Confirm the handle position and that the vat holds oil, then close the valve fully.
2. Inspect the handle and linkage for bending or oil buildup that stops it reaching the closed position.
3. Check the drain-position switch with a meter for correct open and closed states, power off.
4. Check the wiring from the switch to the controller for chafing or a loose connector near the hot area.
5. Adjust the linkage or replace the switch only after the test shows the state is wrong.

How error code Drn / turn / OFF differs from similar codes

The computer control shows this as DRAINING and TURN OFF. The digital controller shows drn, turn and OFF in sequence for the same meaning.
