Troubleshooting
In any situation of problem with the machine understand the reason by consulting the following table. Solve the
problem before resuming normal operation. All operations must be performed with the machine off , without
pressure and disconnected from the power cable plug.
In any situation of block of the machine due to micro lackages, lack of water, the thermal motor protection
intervention and flame failure (photocell) to restart is necessary to return the switch to 0 and wait at least a few
seconds to the next power.
Operations that must be done by assistance technicians
Problem
Cause
Repair
Turning the main switch
ON the machine does not
start
1)Plug not properly connected
2)Main supply fuses blown
3)Transformer fuse blown
1)Check power supply plug
2)Check fuse/replace
3)Check/replace
Electric motor hums but not
start
1) Lack of a phase (vers. Three Phase)
2) Low supply voltage
3) Pump blocked
1)Check power supply fuses
2)Check powe rsupply voltage
3)Check pump
The motor stops suddenly
or after a while
1)Low supply voltage
2)Motor Thermal protection
1)Check power supply
2)Overload/overheating
When the trigger gun is
open the pressure goes up
and down
1)Pressure nozzle dirt or worn
2)Coil or trigger gun dirt with limescale
1)Clean nozzle
2)Clean the coil from limescale
When the trigger gun is
close (by-pass pump ) the
pressure goes quickly up
and down
1)Micro-leaks in pressurized circuit
2)Unloader valve doesn’t work proper
ly
3)Unloader valve dirt or worn
1)Check pressure hose connections. If problem
persists call Assistance.
2) 3) Check/clean unloader valve
Vibration at the trigger gun
and irregular flow
1)Pump valves dirty or worn
2)Unloader valve is dirt
1) 2) Check/replace
Pump runs properly but
doesn’t reach nominal value
1)Low power supply voltage
2)Air suction
3)Pump valve worn
4)Unloader valve worn or dirt
5)Pressure nozzle not correct or worn
6)Leaking from pressure seals
1)Check power supply voltage
2)Check suction hoses of the pump/tighteness
and check water filter
3) 4) Check/clean
5) Check/clean
5) Call Assistance
Lack of pressure
1)Dirt/worn pressure nozzle
2)Inlet/outlet pump valves dirt or worn
3)Unloader valve dirt or worn
4)Air suction
5)Water filter dirt
1)Check/clean or replace
2) 3) Check/ clean or replace
4)Check water pump suction connection
5)Clean water filter
Pump is too noisy
1)Air suction
2)Pump valves springs worn
3)Roll bearings worn (pump or motor)
4)Unloader /pressure fittings dirt or worn
5)Water temperature too hot
1) Check water pump suction connection
2) 3)replace valves/ roll bearings
4)Clean unloader valve and fittings (ejectors
etc.)
5)Verify inlet water temperature
