Internal sensor fault — A built-in sensor is malfunctioning

What does Internal sensor fault mean?

This fault indicates that one of the pump's internal sensors (e.g., for temperature, pressure, or flow) is not providing valid readings or has failed. This can affect the pump's control and protective functions.

• sensor malfunction or damage.
• Loose internal sensor connection.
• Software interpretation error.
• Extreme operating conditions affecting sensor accuracy.

Click steps to track your progress.

1. 1

   Perform a power cycle: switch off the pump, wait 30 seconds, then switch it back on.

2. 2

   Check for any external factors like extreme heat or cold around the pump that might affect sensor readings.

3. 3

   Inspect the pump visually for any signs of physical damage that might impact internal components.

4. 4

   If the error persists, further internal diagnostics or service might be required.
