Troubleshooting
In this section we should like to give you some advice on how you can
clear minor malfunctions yourself.
Switch off the unit and draw out the power plug before undertak-
ing any cleaning or maintenance!
Any investigation of electrical
components may only be carried out by the authorised customer
service.
When there are malfunctions, check the function with both
spray lances.

• Check the mains voltage.
• Check the power cord for damage.
No water comes out of the nozzle or too little
• Check the water supply flow.
• Check the water hose for leaks or obstruction.
• Clean the filter in the water connection
(see “Care and Maintenance”).
• Bleed the unit: let the unit run without high-pressure hose, until water
emerges at the high-pressure outlet free of bubbles. Then connect the
high-pressure hose again.
Water comes out in pulses /The appliance switches on and off.
• Clean the spray lance and vario power nozzle.
Remove clogging from nozzle hole with a needle and rinse again with
water.

sure („–“ direction).

the attachment of the transport handle (see page 4).

Replace defective or crushed O-rings.
