Malfunction Possible cause
Compressor switches on Condensation water in the pressure
and off frequently. tank is too high.
Malfunctions on the high-pressure pump
Rectification
Replace the high-pressure nozzle.
Check the water supply volume (see "Technical data").
Check the suction hose.
Replace the high-pressure nozzle.
Replace the high-pressure nozzle (for size, see "Technical data").
Check the water supply volume (see "Technical data").
Flush the solenoid valve and check the solenoid valve water quality. Check the
float valve.
Refill with detergent. Vent the suction line (if necessary, briefly squeeze the suction
hose to the pump several times during operation to accelerate the venting pro-
cess).
