1. Check the water supply system: confirm whether the water supply system is working normally. Check whether the water source is connected and whether the pipeline is blocked or leaking. Ensure smooth water supply and sufficient water supply.
2. Add water: If it is confirmed that the water supply system is running normally but the water level is still too low, you can try to manually add an appropriate amount of water to the water tank. According to the specific model and description of Dongfeng Tianjin, find the corresponding water injection port and operate according to the instructions.
3. Check the water pump: Dongfeng Tianjin uses a water pump to supply water to the cooling system. Ensure that the water pump is running normally, and there is no fault or damage. If the water pump is found abnormal, you can contact professional and technical personnel for maintenance or replacement.
4. Clean the filter screen: check the filter screen near the water tank and water pump to remove accumulated dirt or impurities. These impurities lead to poor water flow and affect the normal detection of water level.
5. Contact maintenance personnel: If you have tried the above methods but the problem still exists, or you are unfamiliar with maintenance operation, you can contact professional maintenance personnel or Dongfeng Tianjin after-sales service center in time to get more detailed solutions and technical support.
