If your S1 Pro robot triggers the EB1J error code, try the following troubleshooting steps:
-
Remove the dirty water tank from the base station, then lift the top cover to verify that the sealing ring is intact. Apply firm pressure to the entire sealing ring with your hands to ensure that it is properly installed and not inverted, focusing specifically on the two corners adjacent to the left and right sides of the dirty water tank.
-
Tilt the top cover to approximately a 45-degree angle, ensuring that the lower right corner of the sealing ring remains unobstructed by the dirty water tank's support. Then, close the top cover and ensure that the buckle on the dirty water tank is tightly fastened.
-
Verify that the sealing rings for both water inlets of the dirty water tank are correctly installed. If they aren't, please remove them and reinstall them.
The primary cause of the EB1J error code is due to the incorrect installation of the top cover's sealing ring. If the earlier troubleshooting steps did not solve the issue, please watch the following video for additional troubleshooting guidance:
