Troubleshooting
Symptom Cause and Rectification
When the main
switch is turned on
the high-pressure
cleaner will not run. Fault somewhere in the power supply.
Make sure the socket is inserted correctly. Inspect cord for cracks
and wears. Check if fuse is blown, replace if necessary.
The motor is
humming but the
pump does not start. Too low voltage, one phase is missing (on three phase model only)
High-pressure pump is blocked.
Check the mains voltage.
Check the connection box voltage with a meter.
With the machine turned off, turn the motor, at the fan, if it
remains blocked check the pump.
The pressure drops
and the high-
pressure cleaner
works irregularly. The strain filter is clogged or the water supply from the tap is
insufficient.
Clean the strain water filter.
If there isn’t enough water-flow through the tap, ensure sufficient
water supply.
The pump
continuously stops
and starts, when the
spray-gun trigger is
activated.
The high pressure nozzle is partly clogged.
Turn off the high-pressure cleaner, dismantle the high-pressure
nozzle and remove the extraneous matter. Replace if damaged.
The high pressure
cleaner does not
reach the proper
working pressure
when the spray-gun
handle is activated. The high-pressure nozzle is clogged or there is dirt in the by-pass
valve. The pump sucks air.
Turn off the high-pressure cleaner. Clean the nozzle. Inspect the
low pressure supply,
Or while the spray-gun trigger is activated turn the machine on
again. Repeat the procedure again; now with the trigger released.
If the problem still occurs, the by-pass valve should be dismantled
and the extraneous matter removed.
The high-pressure
cleaner only works
with approximately
2/3 of the maximum
pressure, and the
high-pressure hose is
vibrating There is dirt in the valves.
Turn off the high-pressure cleaner. Dismantle the valve bolts and
the valves, remove any dirt and check to ensure the valve flaps are
movable and fits tightly.
