9. Fault finding
9.1 General information
1. Check the mains supply to the pump.
2. Read fault messages by means of Grundfos Eye, Grundfos
GO Remote, PC Tool or R100.
3. If possible, test if the motor can run without load. Remove the
coupling to the pump (if possible) and set the operating signal
to maximum by means of PC Tool, Grundfos GO Remote or
R100.
You can reset a fault indication in the following ways:
• When the fault cause has been eliminated and the pump is
switched on, the pump will revert to normal duty.
• If the fault disappears by itself, the fault indication will
automatically be reset.
The fault cause will be stored in the pump alarm or warning log.
