1. There is no display when turning on the computer. The main reason is that there is no power supply. We need to check the power supply to make sure it is connected correctly.
2. There are many reasons why the water supply is slow and the water level is not rising. This could be because the filter is blocked by something, the connection is unstable, the water is stopped, or the water level is blocked. the water pressure is too low, making it impossible to refill the water. At this time, you must check the connections, then clean the battery filter. Finally, if this is not possible, call a maintenance technician to repair it and replace the corresponding pipes.
