To address this issue, please refer to the following steps:
1. Turn off the power to the dishwasher and wait for a few minutes before turning it back on. This can restart the system and restore communication;
2. If the fault persists, avoid using the dishwasher until the problem is fully addressed, as operating it in this condition could worsen the fault. Additionally, contact the local after-sales service center for professional inspection and repair.
