What to do if the Xiaomi Tabletop Dishwasher displays the error code “-- --”?
The error code “-- --” indicates that the doors on the Xiaomi Tabletop Dishwasher are not fully closed or there can be a malfunction with the door sensor. You can resolve this issue by checking external factors and internal device factors.
To check the external factors, please refer to the following steps:
1. Make sure the doors of the dishwasher are closed tightly;
2. Check that the latches on the lower, inner, left, and right doors are intact and not deformed or damaged.
To check the internal device factors, please refer to the following steps:
1. Ensure that both sides of the lower door are securely pressed and latched closed;
2. If the error persists after securely closing the lower door, disassemble the chassis and use a multimeter to check for continuity on the door lock terminals on the power board (white/white for the right door, white/black for the left door). If the door lock terminals on the power board show continuity, replace the power board. If there is no continuity on the power board terminals, remove the panels on the left and right sides and use a multimeter to check the door lock micro switch for continuity (the micro switch should be normally open and become normally closed when the door is closed). If the micro switch is faulty, replace it. If the micro switch is functioning properly but the lock wiring harness shows no continuity, replace the corresponding wiring harness.
