OBSERVED FAULTS, POSSIBLE CAUSES AND REMEDIES
OBSERVED FAULT
• The water cleaner won't start (pressing the
• black key of the magneto-thermal switch (1))
• During operation the machine stops and the
• magneto-thermal switch (1) switches off
• The water jet is regular but its pressure
• values are very low
• H.P. pump oil shows water traces
• The pump works with irregular pulsations,
• pressure variations and noise
CAUSES
• Electrical supply interrupted/insufficient
• Burnt fuse (T.S. only)
• Electrical supply interrupted/insufficient
• Thermal relay intervention for excessive
• current absorption
• Clogged lance nozzle
• Wrong nozzle
• Bypass valve not calibrated or dirty
• Pump body side sealing ring worn out
• High moisture percentace in the air
• Worn out seals
• Air suction in the water entrance pipe
• Detergent tap open and empty detergent tank
• Blocked bypass valve
• Pump seals worn out
• Inlet/delivery valves obstructed,
• dirty or worn out
• The machine is started without discharging
• the air completely from the circuit
• Worn out bearings
