Flow Error detected — Water circulation issue

What does Flow Error mean?

The system's internal flow sensor has detected an issue with the water circulation within the Heat Pump, which can cause the indoor unit's operation to stop. The current flow rate can be checked on the main remote controller display.

• Restricted or blocked water flow in pipes
• Low water pressure in the heating system
• Malfunction of the flow sensor itself
• Pump not operating correctly

Click steps to track your progress.

1. 1

   Check the main remote controller display for the current flow rate and any specific messages related to water flow.

2. 2

   Ensure all visible isolation valves on the water pipes connected to the Heat Pump are fully open.

3. 3

   Locate the system's water pressure gauge and verify the pressure is within the normal operating range (usually indicated on the gauge itself).

4. 4

   If the water pressure is low, consult your installer for instructions on how to repressurize the system safely.

5. 5

   If the problem persists and the flow remains low or zero, contact a qualified service technician.
