Imagine waking up in the morning only to discover that your RO water purifier has completely stopped working. No water output, blinking lights, strange noises—or even worse, complete silence.
If your Kent, Aquaguard, or any other RO purifier was working perfectly yesterday and suddenly stopped today, you’re not alone. This is a common scenario that many households face.
In this guide, we’ll explore the most likely reasons your RO water purifier stopped functioning overnight and how to troubleshoot them. We’ll also explain when to call a professional for a water purifier service near you to get things running smoothly again.
Is It Normal for an RO Purifier to Stop Suddenly?
While RO systems are generally reliable, they are complex machines with filters, membranes, electrical components, and sensors. Just like any appliance, they can malfunction—especially if regular servicing is ignored.
Issues like clogged filters, electrical failures, or even TDS sensor errors can cause your RO purifier to shut down without warning.
That’s why timely maintenance from a trusted water purifier service in Bangalore is crucial to avoid unexpected breakdowns.
Common Reasons Why Your RO Purifier Stopped Working Overnight
1. Power Supply Issues
Before diving into technical problems, check the basics. Ensure your purifier is plugged in properly, the switch is on, and there’s no power outage in your area.
In some cases, the power adapter may be damaged, especially after a power surge or storm. This is a frequent issue in Bangalore during the monsoon.
Tip: Try plugging in another device to check if the socket works. If the purifier’s lights don’t turn on, it could be a power adapter issue.
2. Faulty SMPS (Switched Mode Power Supply)
Every RO purifier, including Kent and Aquaguard, uses an SMPS to regulate power. If this fails, the entire system will shut down.
A failed SMPS can be replaced easily by a technician from a water purifier shop near you or through a scheduled Kent RO service near me.
3. Clogged Pre-Filters
Pre-filters are the first line of defense in your RO system. They capture larger particles like sand, dirt, and rust. When they get clogged, water stops flowing through the system.
If your water pressure is fine but your purifier is not dispensing water, a clogged pre-filter might be the cause.
It’s a common issue among households that delay their regular water purifier service.
4. RO Membrane Failure
The RO membrane is the core component of your purifier. It removes dissolved salts, heavy metals, and bacteria. Over time, the membrane can become saturated or blocked, especially if the TDS of your input water is high.
Once the membrane fails, the system may stop producing water altogether or start rejecting too much water.
You may need to book a Kent water purifier service or water filter service near me to test and replace the membrane.
5. Malfunctioning Float Valve in the Storage Tank
If your purifier’s storage tank is full but the float valve fails to detect it, the system may stop refilling or shut off entirely to avoid overflow.
This is often caused by debris or mineral scaling inside the tank or valve mechanism. Technicians from a water purifier shop near you can clean or replace the float valve during a standard service.
6. Pump or Solenoid Valve Failure
The pump is responsible for moving water through the RO membrane. If the booster pump or solenoid valve fails, your system won’t operate.
You may hear unusual clicking sounds or complete silence. These electrical parts can burn out over time, especially in areas with voltage fluctuations—common in many parts of Bangalore.
A visit from a water purifier service technician will be needed to replace faulty components.
7. TDS Controller or Sensor Issue
Some RO systems have an inbuilt TDS controller or sensor that monitors water quality. If this sensor malfunctions, it may prevent the purifier from running, thinking the water isn’t safe.
Only a trained technician can test or recalibrate these components, so this is another reason to book a water purifier service near me as soon as you notice the issue.
8. High TDS or Input Water Pressure Issues
In certain cases, extremely high TDS or pressure from borewell water can cause the system to shut down. RO systems are designed to work within a specific pressure range.
Too much pressure can damage internal components or lead to automatic shutdown. Installing a pressure regulator is often recommended by technicians during a Kent RO service or Aquaguard service near you.
9. Blocked or Damaged Pipes
Sometimes, the reason could be as simple as a kinked pipe, blockage, or internal leakage. This can prevent water from flowing to and from the tank or membrane, especially in older systems.
This kind of issue is hard to spot without opening the unit, so calling a certified water purifier service provider in Bangalore is your best option.
