Troubleshooting
If, despite the high
standard of quality, faults should occur, please use the checklist
below to rectify or restrict the problem. A number of faults are already detected and
displayed by the electronics.
If you cannot rectify the fault by checking the lines (incorrect connections), mains
voltage, and pump (smooth running, blockages), please contact your specialist dealer.
In such cases, please be ready to state the serial number of the driver and of the
motor. The serial numbers are on the blue serial number sticker or on the packaging.
