Troubleshooting a Water Filtration System: When the Machine Stays Silent but the Water Keeps Flowing - Causes and Effective Home Solutions

Encountering a situation where the water filtration system remains inactive while wastewater continues to flow is a common issue. Wondering about the reasons and how to address this concern? Let's explore the problem with Supermart Mytour in the following article!

When the water filtration machine is silent, but wastewater persists

Water purifiers are ingeniously designed devices aimed at eliminating impurities, bacteria, and various compounds from water to produce clean and safe drinking water for daily activities.

In today's market, various water purifier models utilize different filtration technologies such as RO water purification, Nano water purification, UF water purification technology, and more. Each type of water purifier is equipped with its own method to eliminate different pollutants.

The Benefits of Using Water Purifiers

Utilizing water purifiers brings numerous health and environmental benefits:

● Provides clean and safe water for daily consumption and usage.

● Minimizes water resource depletion.

● Saves costs on purchasing bottled water.

● Ensures that the water used is safe and does not impact the health of users.

● Provides convenience and flexibility in water usage for daily activities, reducing reliance on public water sources.

Currently, there are various types of water filtration systems, each with its own pros and cons. Users need to research and choose carefully to fully harness the benefits of using water purifiers.

Cause: Most water filtration systems utilize a filtration membrane to eliminate harmful impurities in water. If this membrane is damaged or reaches the end of its lifespan, wastewater may flow through the membrane without filtration, leading to the issue of the water filtration system not running while wastewater continues to flow.

Damaged Filtration Membrane

Solution: If the filtration membrane is damaged or has reached the end of its lifespan, replace it with a new one. This ensures that the filtered water is safer, and it prevents wastewater from flowing out when the system is not in operation.

Cause: The solenoid valve is a component that closes when the machine is off and opens when the machine is in operation. After a period of use, the solenoid valve may become stuck due to impurities entering with the water source and gradually accumulating into deposits. Alternatively, the solenoid valve may be beyond its useful lifespan, causing it to malfunction and resulting in wastewater flowing while the machine is not running.

Valve Malfunction

Solution:

Check the voltage input to the solenoid valve. Measure the voltage of the solenoid valve; if no voltage is detected, recheck the wiring and power source.

Remove the solenoid valve and check for any foreign objects in the pipeline. If found, clean the solenoid valve and reinstall it.

If the solenoid valve is damaged, proceed to replace it with a new one.

Cause: The check valve (also known as the one-way valve) functions to allow water to flow from the RO membrane into the pressure tank. However, during operation, the check valve may become faulty, causing water from the RO membrane not to flow into the pressure tank but instead reverse and discharge in the wastewater line when the water filtration system is inactive.

Faulty Check Valve

Solution: Check the check valve; if it's clogged with debris, clean it under a water stream. After cleaning, reinstall the valve in its correct position and start the machine to see if it operates normally. If the issue persists, the check valve may be damaged and needs replacement.

Cause: During the installation of the water filtration system, if all the air is not purged from the filter cup before starting the machine, an airlock situation may occur. If not addressed promptly, it can cause blockage in the check valve, leading to the phenomenon of the water filtration system not running while wastewater continues to flow.

Airlock Causing Check Valve Blockage

Solution: To address this issue, follow the instructions below:

Step 1: Turn off the power, shut off the water supply to the machine, and close the water filter tap and pressure tank valve.

Step 2: Locate the filter core position, remove the valves from cores 1, 2, 3, fill the filter cup with water, and tighten it back securely.

Step 3: Replug the power, open the water supply, water filter tap, and pressure tank valve to restart the machine.

Cause: Insufficient pump performance can also lead to wastewater flow despite the water filtration system being inactive. If the pump is not running, the filtration membrane will get blocked, resulting in no clean water and complete conversion to wastewater.

Weak Pump Performance

Solution: Check the pump by temporarily blocking the wastewater flow and assess the water pressure. If the water pressure is low, indicating weak pump performance, replace the pump for better stability of the water filtration system.

Note: If you lack electrical skills and knowledge, seek assistance from technical experts at the service center to ensure safety and avoid worsening the water filtration system's damage by attempting DIY repairs at home.
