adapter not screwed in correct-
ly or completely.
Power supply interrupted
Pre-filter is dirty
The appliance is in the auto-

Pressure in the system >
1.3 bar.
Failure on the suction side,
pressure cannot build up
Flow rate very low -> the dry
run protection has switched off
the pump.
Fault delivery side (leakage or
closed tap) during suction.
Pump does not end the suction
