Troubleshooting

Reason
> A fuse has blown
> Power/plug not connected
> Thermal switches in motor activated
(red lamp fl ashes) #5
> Thermal relay switched off (red lamp
fl ashes) #5
> Oil shortage in pump
> Installation does not correspond to the
ampere consumption of the machine
> Nozzle worn
> Wrong spray lance
> Too many users on the system
> Reduction valve of spray lance not
adjusted to max. pressure.
> Nozzle partly clogged up
> Water temperature too high
> Insuffi cient water supply to pumps
> Air in the system
> Water fi lters clogged up
> Nozzle clogged up
> No inlet water
> High pressure cock of outlet point open.
> Oil shortage in pump. Lamp fl ashes #6 • Top up with oil.
Action
• Change the fuse.
• Connect power/plug.
• Let the motor cool. Start the machine
and check that the working pressure is
not too high and that the mains voltage
corresponds to the specifi cations.
• Refi ll with oil.
• Change to an installation corresponding
to the ampere consumption of the ma-
chine at a minimum. Replace the fuse.
• Replace the nozzle.
• Replace the spray lance.
• Turn reduction valve completely counter-
clockwise.
• Clean the nozzle (see section C.3).
• Lower the temperature of the inlet water
to max. temperature (see Technical
Specifi cations).
• Check water inlet fi lter + fi lter in water
tank. If that does not solve the problem,
the water supply for the machine is
insuffi cient.
• Vent the system (see section A.7).
• Clean fi lters (see sect. C.2)
• Clean nozzle (see sect. D.3)
• Check that the shut off cock of the wa-
ter inlet is open. Check that the water
supply meets the requirements
(see section A.4)
• Close all high pressure cocks not in
use.
• Repair leak.
