Dry running (57) - Water is missing or system pressure is too low

What does 57 mean?

The pump is running without sufficient liquid or the system pressure is below the required minimum. This is a protective measure to prevent pump damage, but it halts normal operation.

• Insufficient water in the heating system or circulating loop.
• Air pockets trapped inside the pump.
• System pressure being too low, below the pump's minimum inlet requirements.

1. 1

   Check the system's water level and ensure it is adequately filled according to system specifications.

2. 2

   Increase the system pressure to the recommended level if it is too low.

3. 3

   Prime and vent the pump thoroughly before attempting to restart it to remove any trapped air.

4. 4

   Ensure all isolating valves on the pump's inlet and outlet are fully open.
