1. Water Filter Has No Electricity
If the water filter lacks electricity, both the pump and the entire system will fail to operate.
Reasons for Water Filter Power Failure:
Loose plug
Damaged power cord
The electrical wire is damaged due to either a break in the wire or a faulty electrical outlet.
Solution:
Firstly, check if the plug is securely inserted. If loose, plug the electrical wire again firmly. If this doesn't work, replace the plug or the electrical outlet.
Test the functionality of the electrical outlet by plugging in devices such as a phone charger, fan, or other electrical appliances. If it still doesn't work, consider inspecting your home's electrical system.
If this issue persists, check if there are any rodent bites or breaks in the washing machine's electrical system.
2. The input does not have water supply.
If there's no water supply to the water filter, it won't function properly.
Several factors can lead to this situation:
- Water supply depletion, weak water source, or blocked water pipes.
- Water supply valve turned off.
- Weak or faulty water pump preventing the filtration system from operating.
- For water filters without a pump, this issue commonly occurs, rendering the device non-functional.
Solution:
- Remove the water supply hose from the machine and check the water flow rate. If it's not stable, inspect the water source.
- If the water supply is blocked, locate and clean the blockage. If the water source is normal, check the pump's operation.
3. Faulty low-pressure valve of the water filter
The low-pressure valve's role is to block water flow into the water filter when the water pressure is insufficient. If the low-pressure valve is faulty, water won't flow through, rendering the water filter inoperative.
Check the low-pressure valve's operation by connecting two electrical wires to it and rubbing them together to see if there's an electric spark. If yes, the valve is functioning properly; otherwise, it may be damaged.
4. Malfunctioning high-pressure valve
The high-pressure valve acts as a switch to control the water output based on pressure differentials.
You may notice a warning sign of a faulty high-pressure valve when the pump doesn't operate despite the water source being open and electricity plugged in.
5. Blocked water filter cartridge
A blocked water filter cartridge prevents water from flowing through, causing the device to malfunction.
Water filter cartridges have a certain lifespan. Blockage may occur due to inadequate cleaning, allowing dirt to accumulate.
Solution:
Regularly clean the filter cartridge to ensure cleanliness.
If the water filter cartridge is dirty, replace it to ensure the best water filtration quality.
6. Power Adapter Burnout
Turning the water filter on and off multiple times or unstable power supply can cause the power adapter to burn out.
The reasons for this situation are:
- Power instability, whether strong or weak.
- Old device, purchased long ago but hasn't had the adapter replaced due to issues.
Solution:
First, use a voltmeter to check if the adapter has been charged.
Next, rub the two outputs of the power supply to check for electricity. If there's no electric spark, it's likely that the power supply has burned out.
If the adapter is damaged or burnt, you should replace it with a new one.
7. RO Membrane Blockage
After prolonged water filtration, the RO membrane may become blocked, causing the water filter to malfunction.
The reasons for this issue are:
- Using the water filter for an extended period without replacing the filter cartridge, especially after one year.
- Using dirty water sources that haven't been properly treated, such as rainwater or well water.
Solution:
You should replace the RO water filter cartridge as it cannot be cleaned like regular filters. Since the RO water filter cartridge is the final filter in the filtration system, it directly impacts the quality of the water source. Simply cleaning the RO water filter cartridge will only reduce dirt but cannot completely clean it.
8. Pump Malfunction
Due to prolonged operation of the water filter with high frequency, the pump may become faulty.
Solution: Replace the pump with a new one as this is a difficult-to-repair component, and repairing it will weaken the water filter's operation. A faulty pump will affect the water filtration efficiency and consume significant electrical energy.
