...do it yourself !
Nozzle dirty or sticky!
Pressure gauge does not show full pressure
Water comes out in spurts.
If you do not use the high-pressure cleaner for some time the valves can stick.
The high-pressure hose vibrates.
Straighten a
paper clip...
When a valve is
blocked,
the gauge
shows little
pressure or
no pressure
at all
or the high
pressure
hose
vibrates!
Open the valve
with a socket
wrench...
and remove the
valve screw, the
valve and the
o-ring.
Replace the rubber o-ring.
and remove the
dirt from the valve
- the valve inside
must be closed.
Retighten the
valve screw
...and repeat
on all 6 valves.
Now it works
as well as
before!
