What this code means

This test is carried out when the pump motor is running, and it verifies that the current feedback sensor is not constantly stuck to 0.

Applies to: ZAPI ACE0 / COMBIAC0 controller.

Possible causes / checks (from the source)

A) Check the motor connection, that there is continuity. If the motor connection is opened, the current cannot flow, so the test fails and the error code is displayed. B) If everything is ok for what it concerns the motor, the problem could be in the current sensor or in the related circuit.
