How to Fix Water Purifier Autocut Problem? Complete Guide with Expert Tips

Clean and safe drinking water is essential for every household, and a water purifier plays a crucial role in ensuring your family's health. However, one of the most common issues users face is the autocut system not working properly. When the autocut function fails, the purifier may overflow, stop filtering, or repeatedly start and stop, leading to both water wastage and machine damage.

Being a trusted and most admired service provider, Bhola Ro Service understands these technical concerns deeply. With our years of expertise, we ensure that your RO system operates smoothly with preserved performance and long-lasting durability.

This comprehensive guide will help you understand why the autocut problem happens, how to diagnose it, and steps to fix it effectively at home. However, if professional care is needed, we strongly recommend contacting Bhola Ro Service for expert inspection and repair.

Understanding the Autocut Function in Water Purifiers

The autocut mechanism is designed to automatically stop the water purifier when the tank is full. This prevents unnecessary water flow and saves electricity. The autocut system works through:

  • Float Valve / Water Level Sensor

  • Pressure Switch

  • Solenoid Valve

  • Pump Control Circuit

When any of these components fail or malfunction, the RO system cannot detect the water level accurately and the autocut feature stops functioning properly.

Common Symptoms of Autocut Problems

You may be experiencing an autocut issue if:

  • The RO keeps running continuously, even when the tank is full.

  • Water overflows from the purifier’s top or side vent.

  • The RO starts and stops frequently, causing an irritating clicking noise.

  • The purifier fails to start even if the tank is empty.

  • Low water output even after several minutes.

Major Causes of Autocut Failure in Water Purifiers

1. Faulty Float Valve

The float valve is responsible for sensing the water level. If it gets stuck, damaged, or blocked, it fails to send the right signal.

2. Pressure Switch Malfunction

The pressure switch controls pump operations. Any failure in this switch affects the autocut process.

3. Blocked or Faulty Solenoid Valve

If the solenoid valve is clogged due to sediment or scale deposits, water flow is disrupted.

4. PCB Circuit Damage

The printed control board sends signals to operate the pump and cut-off mechanism. A damaged PCB can prevent the system from working correctly.

5. Sediments in Water Tank or Filters

Accumulated dirt and heavy sediments influence the water flow and cause signal failures.

Step-by-Step Guide to Fix Water Purifier Autocut Problem at Home

Note: Perform these steps only if you feel comfortable. In case of any difficulty, Bhola Ro Service is ready to help with expert technicians.

Step 1: Turn Off Power and Water Supply

Safety first. Switch off the purifier and close the inlet valve.

Step 2: Inspect the Float Valve

  • Open the top lid of the tank.

  • Check if the float is moving freely.

  • Clean with warm water if any debris is stuck.

  • Replace the float if it appears damaged.

Step 3: Check the Pressure Switch

  • Remove the switch wires.

  • Test continuity using a multimeter.

  • If readings are unstable, the switch needs replacement.

Step 4: Clean the Solenoid Valve

  • Remove the valve from the line.

  • Soak it in vinegar/warm water solution for 20 minutes.

  • Rinse thoroughly and reinstall.

Step 5: Check the PCB and Pump Relay

If your RO still does not autocut:

  • The relay controlling the pump may be faulty.

  • PCB repair or replacement may be required.
     This is best handled by a trained RO technician.
