Reasons why the water control machine still gets water: 1. Main controller problem; 2. Solenoid valve problem.
用万用表测量连接电磁阀两根线的电压， 水控机刷卡开始后测量是否电压达到12V左右，拔卡或按停止键后电压是否为零。 1. Use a multimeter to measure the voltage of the two wires connected to the solenoid valve. After the card is swiped, measure whether the voltage reaches about 12V, and whether the voltage is zero after pulling out the card or pressing the stop button.
如果按停止键后电磁阀依然有电压，说明主控器问题。 2. If the solenoid valve still has voltage after pressing the stop button, it means that the main controller is defective.
如果电磁阀电压开关正常，说明是电磁阀问题，更换新电磁阀即可。 3. If the solenoid valve voltage switch is normal, it indicates that the solenoid valve is faulty. Replace the solenoid valve with a new one.
The above is a common method to solve this situation. If you have any other questions, please 世界杯波胆赔率 in time!
