What to do if the screen of the Xiaomi Tabletop Dishwasher displays the E3 code?

The E3 code indicates a washing water shortage fault.
To resolve this issue, please refer to the following solutions:
1. Turn off the power and ensure the dishes are arranged correctly, making sure they do not block the spray arms or interfere with water circulation. Then, turn the power back on;
2. Turn off the power and check the filter for any blockages caused by food debris or grease. Clean it if necessary, and then turn the power back on;
3. Turn off the power and verify that the filter is properly installed. If it is loose or improperly placed, reinstall it securely before turning the power back on;
4. If the problem persists, turn off the power and water supply and contact the local after-sales service center for professional inspection and repair.
