14.2 Fault resetting

You can reset a fault indication in one of the following
ways:
• When you have eliminated the fault cause, reset
the pump manually by pressing the Reset button.
The pump will then revert to normal duty.
• If the fault disappears by itself, the pump will
attempt to reset automatically and the fault
indication will disappear if automatic reset is
successful and provided that you have enabled
the auto reset function in the service menu.
