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 machine does not start
• During functioning the pump stops
• Vibrations in the delivery pipe or functioning with
•
irregular pulsations, variations in pressure and
•
noise level
• Noisy pump
• The burner does not start and block light 7
•
(Fig. 2) comes on
• The water temperature does not reach the level
•

10. DISPOSAL AND SCRAPPING
When you decide to render the high pressure cleaner unusable, the electricity supply cable must be removed and the rating plate taken off. In addi-
tion, it is necessary to prevent any high pressure cleaner components from posing a danger. The high pressure cleaner constitutes special refuse, and
hence it is necessary to dismount and divide it into homogenous parts, disposing of it in accordance with current national laws. Do not use pieces of the
scrapped high pressure cleaner as spare parts.
CAUSES
• Electricity supply interrupted or insufficient
• Electricity supply interrupted or insufficient
• The pump does not start
• The pump aspirates
• Pump seals worn
• Pump bearings worn
• No diesel supplied
• Damaged diesel motor/pump coupling joint
• Diesel nozzle dirty or ruined
• Air infiltrations in the diesel aspiration piping
• Diesel solenoid valve not functioning
• Weak or absent ignition spark
• Lack of water in the hydraulics system
• Intervention of the safety thermostat resetting
• Fuel supply is insufficient

•
voltage
• Check the electricity supply specifications
• Check the electricity connections and network
•
voltage
• Repeat the operations in the paragraph
• Check for the presence of any losses and tighten all
•
junctions
• Replace the seals
• Replace the bearings
• Check the diesel level; if necessary, fill the tank
• Clean and/or replace the diesel pump
• Clean and/or replace the diesel filter
• Replace the joint
• Clean the nozzle with compressed air or with diesel
•
oil and replace it if necessary
• Check the tightness of all junctions
• Clean and/or replace the solenoid valve
• Check the ignition transformer
• Check the electrodes
• Check the hydraulic system and water pressure
•
switch
• Reset the safety thermostat and where the defect
•
occurs again switch off the machine and request
•
the assistance centre to intervene
• Clean the diesel nozzle and/or diesel filter
