Why Is My Pura Flashing Blue? Common Reasons and Solutions

If your Pura water filter system is flashing blue, it can indicate an issue that needs attention. Understanding why this is happening and how to address it is essential for the proper functioning and maintenance of your device. In this article, we will explore common reasons why your Pura might be flashing blue and provide some solutions to help you resolve the issue.

1. Insufficient Water Flow

One possible reason for your Pura water filter system flashing blue is insufficient water flow. When the water flow drops below the minimum requirement, the system signals an error by flashing blue. This can occur due to various factors:

  • Clogged or dirty filters: Over time, the filters can accumulate debris and contaminants, reducing water flow. Regular cleaning or replacement of filters is crucial to maintain optimal flow.
  • Mismatched filter size: Ensure that you are using the correct filter size for your specific Pura system model. Incorrect filter sizes can impede water flow.
  • Low water pressure: If the water pressure from your source is too low, it can result in reduced flow. Check the water pressure and make necessary adjustments.

To address issues related to insufficient water flow, follow these steps:

  1. Inspect the filters: Remove and clean the filters according to the manufacturer’s instructions. If the filters are old or damaged, consider replacing them.
  2. Check the filter size: Ensure that you are using the appropriate filter size for your Pura system. Refer to the user manual or contact customer support for guidance.
  3. Verify water pressure: Use a pressure gauge to measure the water pressure from your source. If it’s too low, consider installing a booster pump or contacting a plumber to address the issue.

2. Incorrect Installation

Another reason for the blue flashing light on your Pura water filter system can be incorrect installation. Improper installation can lead to functional problems and trigger error signals. Some common installation-related causes include:

  • Loose connections: Ensure all the connections between filters, tubing, and the Pura device itself are secure and properly tightened.
  • Misaligned parts: Check if any component or part is misaligned or incorrectly fitted. Realign them as necessary to ensure proper functioning.
  • Missing or incorrect gaskets: Gaskets are essential for creating watertight seals. Make sure you have included all the necessary gaskets and that they are the appropriate size for your system.

To address issues related to incorrect installation, follow these steps:

  1. Inspect connections: Examine all the connections in your Pura system. Tighten any loose fittings and ensure they are properly aligned.
  2. Check gaskets: Verify that all the required gaskets are present and correctly positioned. Replace any damaged or misplaced gaskets.

3. Power or Control Board Issues

In some cases, when your Pura water filter system flashes blue, it could indicate problems with the power supply or control board. These issues might prevent the system from functioning correctly. Here are a few potential power or control board-related causes:

  • Power outage or interruption: Check if there has been a power outage or interruption and ensure that the power supply to your Pura system is stable.
  • Control board malfunction: A faulty or malfunctioning control board can result in error signals. It may need to be repaired or replaced by a professional.

To troubleshoot power or control board issues, consider the following:

  1. Verify power supply: Ensure your Pura system is receiving a consistent power supply. Check the circuit breaker, power outlet, and any other relevant power sources.
  2. Contact customer support: If you suspect a control board issue, reach out to Pura’s customer support for guidance on how to proceed. They can provide valuable assistance or arrange for a repair if needed.

4. Low UV Lamp Life

If your Pura water filter system utilizes a UV (ultraviolet) sterilizer, the blue flashing light might indicate low UV lamp life. UV lamps lose their effectiveness over time and require replacement. Here’s how you can address low UV lamp life:

  • Check UV lamp status: Consult your user manual to determine how to verify the UV lamp’s status. Some Pura systems have a built-in timer that indicates when lamp replacement is necessary.
  • Replace UV lamp: If the UV lamp has reached the end of its recommended lifespan, replace it with a new one following the manufacturer’s instructions.

5. Sensor or System Error

A sensor or system error can also trigger the blue flashing light on your Pura water filter system. This type of issue requires further investigation or professional assistance. Here’s how you can approach it:

  • Reset the system: Try resetting your Pura system by turning it off and unplugging it for a few minutes. Then, plug it back in and start it again to see if the flashing blue light persists.
  • Contact customer support: If the issue persists or if you suspect a sensor or system error, reach out to Pura’s customer support. They can provide guidance or arrange for repairs if necessary.

In conclusion, a Pura water filter system flashing blue can indicate various underlying issues, including insufficient water flow, incorrect installation, power or control board problems, low UV lamp life, or sensor/system errors. By diagnosing the problem correctly and following the appropriate steps outlined above, you can address the issue effectively and ensure the optimal performance of your Pura water filter system.
