There are many reasons. 1 It may be that the operation of replacing the filter element is improper, and there is an error in the process of installing the filter element, which leads to the filter element not working. 2. It may be that there is no reset after replacing the filter element. Because the reset button is not pressed after replacing the filter element, the memory of the failure of Jiuyang water dispenser cannot be erased, and the water dispenser still retains the original memory, so the prompt light will keep flashing. 3. There may be some problems with the low-voltage switch, high-voltage switch and water level control function of Jiuyang drinking machine.

Suggested treatment:

When the power supply is turned off, remove the filter element and check whether the filter element is damaged. If it is normal, it needs to be correctly installed in the water dispenser again.

After replacing the filter element, you need to press the reset button in Jiuyang water dispenser. The function of this button is to erase the memory of the filter element of Jiuyang water dispenser before. Only in this way can the memory of the filter screen of the water dispenser be recalculated, and the prompt light will not be on all the time. If you don't press the reset button, the drinking machine can't automatically identify whether a new filter element has been replaced, which causes the warning light of Jiuyang drinking machine to keep flashing.

Disconnect the power supply of the water dispenser, and turn on the water dispenser again after 10 minutes to prevent poor contact and unstable circuit of the water dispenser.

Use the instruction manual to determine the cause of the flashing of the failure light of the water dispenser. If there is a problem with the pressure pump or solenoid valve, please contact the after-sales service of Jiuyang products for help.
