What does MEIKO error code 963 / 969 / 971 mean?
Besides running the wash, the M-iClean U has an operating panel with a color display, a Bluetooth link and a small backup battery that keeps the clock and settings alive. The three numbers here belong to that panel rather than the wash. Message 963 is a Bluetooth access error, 969 says the backup battery is in critical condition, and 971 says the operating panel is re-initializing, which is a restart. They appear in the gray group of operator messages, so the manual treats them as notices staff only need to acknowledge. The maker's step is to confirm the message and to call a service technician if it repeats. A restart after a power dip is common and clears alone. A battery notice can appear on its own after years, and a Bluetooth error often only matters to whoever is trying to connect a phone or service tool. A message that comes back day after day suggests a worn battery or a panel board that needs attention.

Do these messages stop the machine?
No. The washing itself continues; they only need to be acknowledged.
What does 969 mean for me?
The backup battery on the control is in critical condition. The machine washes, but settings could be lost on a power loss.
What if 971 shows every day?
Then the panel keeps restarting, and a technician should look at the power and the panel board.
