Water flow alarm faults are a common and frustrating issue in the daily operation of chillers. These faults are usually caused by one of the following reasons: a dirty filter, air in the pump, or internal pump failure. To help you quickly and effectively address these problems, this article will detail the causes of each fault and the corresponding solutions.

Common Faults and Their Causes

1. Dirty Filter: When the filter becomes clogged with dirt, it can severely restrict water flow, leading to insufficient water circulation and triggering a water flow alarm. This issue often arises due to infrequent cleaning or replacement of the filter.

2. Air in the Pump: If the pump has drawn in air, it may cause unstable or insufficient water flow, which can also trigger a water flow alarm. This typically occurs due to poor sealing in the water pipes, allowing air to enter the system.

3. Internal Pump Failure: Over time, the internal components of the pump may wear out or fail, compromising its ability to function properly and ultimately causing a water flow alarm. This issue is common in older equipment or units that have not been adequately maintained

Troubleshooting Steps and Solutions

To address the above faults, you can follow these troubleshooting steps:

1. Replace the Filter and Check the Seals Steps:

   • Shut Off Water Flow: Before replacing the filter, ensure that the water flow is turned off to prevent water from continuing to enter the equipment.
   • Replace the Filter: Open the filter housing, remove the old filter, and replace it with a new one. A clean filter will ensure smooth water flow and prevent alarms.
   • Check the Seals: While replacing the filter, inspect the seals inside the filter housing for any damage or wear. Replace any worn or damaged seals to ensure proper sealing.

2. Remove Air from the Pump Steps:

   • Check Water Pipe Seals: Carefully inspect the inlet and outlet water pipes to ensure that all seals are intact and the nuts are tight, preventing air from entering the system.
   • Air Purging: If air has entered the pump, you can try releasing it through the air purge valve, or restart the equipment and check if normal water flow is restored.

3. Inspect and Repair the Pump Steps:

   • Check Pump Condition: After shutting down the equipment, inspect the pump for any unusual noises or vibrations, which may indicate internal component wear or failure.
   • Replace Damaged Parts: If internal pump issues are confirmed, it is recommended to replace the damaged parts or replace the pump entirely to restore the equipment to normal operation.
