¶ Fault Phenomenon
The printer failed the Resin tank self-test. The touch screen displays the error message “Equipment malfunction please troubleshoot”
¶ Possible Causes
- The automatic feeding assembly is lifted and not lowered.
- Hall sensor failure.
- Insufficient magnet strength in the resin tank or the magnet is missing.
¶ Required Tools
- Magnet
- 2.5 mm hex screwdriver
¶ Troubleshooting Steps
¶ 1.Check the Automatic Feeding Assembly
If the automatic feeding assembly is lifted, manually lower it to the original position. If it is already in the lowered position, repeat the lift + lower action several times and re-run the self-test.

¶ 2.Check the Hall Sensor
-
Turn off automatic feeding via the touch screen (Settings → Accessibility → Resin recycling).

-
Lift the automatic feeding assembly.

-
Place the magnet on the upper center of the automatic feeding assembly (the Hall sensor cannot detect the magnet in other positions).
Remove the magnet immediately after the test.

- Re-run the self-test via the touch screen.
-
If the error still occurs, the Hall sensor needs to be replaced (the Hall sensor is located inside the automatic feeding assembly).

-
If the error no longer occurs, continue with the following steps for further troubleshooting.
¶ 3.Check the Resin Tank
-
If you have another resin tank, try replacing it for testing. If the error disappears with a different tank, the magnet in the original tank may have fallen off or lost magnetic strength. Proceed with the steps below.
-
Lift the automatic feeding assembly.
-
Use a sealing bag and zip tie to seal the resin outlet of the automatic feeding assembly.

-
Remove the two straight-grain handles/resin tank.

-
Use the 2.5 mm hex screwdriver to remove the three screws securing the resin tank baffle and take off the baffle.

-
If the magnet is not missing, its magnetic force may have decreased. Replace it with a new magnet.

¶ Still Not Resolved
If the issue persists after completing steps 1–3, please contact technical support by email (3dp@elegoo.com). To help us diagnose the problem faster, please provide the following information and the results of the troubleshooting steps above:
- A video recording of the error reproduction process. The video must clearly show whether the automatic feeding assembly is lifted and then lowered, and the moment the touch screen error appears.
- Results of steps 1–3:
- Is the automatic feeding assembly lowered?
- Does the self-test pass when the magnet is placed on the upper side of the automatic feeding assembly?
- Is the magnet inside the resin tank missing?
