9. PROBLEMS, CAUSES AND SOLUTIONS

The table below lists the main functional problems, with relative causes and solutions. If you have a problem that is not listed, or for information re-
garding different causes and solutions, contact one of our technical assistance centres.
OPERATIONAL PROBLEMS
• The high pressure cleaner does not start
• Having pressed the switch, the motor makes
• a noise but does not start
• During functioning the machine stops
•
• The water jet is regular, but with very
•
low pressure values
• During functioning the pressure is irregular
•
•
• Vibrations in the high pressure pipe or the
pump functions with irregular pulsations,
variations in pressure and noisiness
• Noisy pump
• The H.P. pump oil displays traces of water
(the oil takes on a whitish colouration)
• Loss of water between head and pump body
• Loss of oil between head and pump body
CAUSES
• Electricity supply interrupted or insufficient
• The mains voltage is less than the minimum
• required
• Electricity supply interrupted or insufficient
• Intervention of the thermal relay due to
excessive absorption of current
•
• Nozzle worn
• Nozzle unsuitable for the machine type
• Water supply filter clogged
• Defective water network connection
• Worn pump gaskets
• Deformed or clogged nozzle
• Hydraulic supply interrupted or insufficient
• The pump sucks air up
• Air inside the piping
• Pump gaskets worn
• Inlet and/or delivery valves of the pump are
• blocked, dirty or worn
• Machine start-up without having completely
• discharged the air from the circuit
• Pump bearings worn
• Pump gaskets worn
• Worn gaskets
• Worn pistons
• Pump body side seal rings worn

• Check the hydraulic network
• Check for the presence of any leaks and tighten
• all the junctions
• Detach the spray gun of the H.P. pipe and allow
• the water to exit for some minutes with the
• machine on
• Replace the gaskets
• Check the closure surfaces of the valves and
• clean them or replace the valves
• Remove the spray gun and allow the H.P.
• pump to function for a few seconds
• Replace the bearings
• Replace the gaskets
• Replace the gaskets
• Replace the pistons
• Replace the seal rings
