There are several reasons why the indicator light of Haier water purifier flashes completely. You can check whether there is power failure, whether the plug is plugged in properly, whether the low-voltage switch fails, whether the power supply cannot be connected, whether the high-voltage switch or water level controller fails to reset, and whether the transformer and fuse are burned.
After the filter element of the water purifier is replaced, the light still flashes all the time for the following reasons;
1. The filter element is not installed correctly.
2. The light on the filter element of the water purifier prompts the user to replace the filter element, which needs to be reset and recalculated after replacement.
3. The indicator light represents five layers of filter elements, and the usage of each layer of filter element will be displayed through the indicator light. The first layer is pp cotton, the second layer is granular carbon, the third layer is compressed carbon, the fourth layer is ro membrane, and the fifth layer is post-activated carbon. Each layer of filter elements plays a different filtering role, so it is necessary to judge the fault type.
4, low voltage switch failure, high voltage switch or water level controller failure.
5. The high-pressure pump loses pressure, the front filter element is blocked (there is no pure water wastewater or little wastewater), the check valve is blocked (there is wastewater without pure water), and the solenoid valve fails and cannot be effectively opened.
Solutions;
1. Disconnect the power supply, remove and reinstall the filter element, and then turn on the power supply.
2. After replacing the filter element, you need to press the reset button of the control panel. The reset button is used to clear the memory of the filter screen and recalculate. If you don't press the reset key, the original memory of the filter screen will still be saved, causing the indicator light to keep flashing and give an alarm.
3. Read the instruction manual, and judge the specific alarm content and treatment method of the flashing fault light.
4. Turn off the power of the water purifier for 5 minutes, and then restart it.
Prompt; If the above methods cannot be solved, it is recommended to contact the manufacturer for after-sales consultation!
