Table of troubleshooting
Problem
Smoke from chimney
Lack of pressure from outlets
Lackage from close steam gun
Lackage from safety valve
Detergent pump doesnt start
The detergent pump works
but no detergent comes out
Vibration and noise coming
out from steam solenoid
valves
Water pump runs but without
correct flow rate
Steam comes out from closed
solenoid valves
No pressure (when starting
the machine the fan runs a
few seconds then stops)
Cause
1)Combustion not correct
2)Dirt boiler
3)Boiler cold and not ready
4)Fuel not correct
1)Limescale in steam hoses and
fittings
2)Steam trigger gun dirt
1)Steam gun with limescale
2)Over pressure
1)Overpressure of the boiler
2)Safety valve dirt or worn
1)Low detergent level
2)Detergent pump fuse blown
3)Cabled hose failure connections
4)Steam trigger switch failure
1)Detergent pump with air inside
2)Detergent pump damaged
1)Solenoid coil not tighten
2)Dirt inside solenoid valve
1)Water filter dirt or clogged
2)Water pump damaged or worn
1)SOlenoid valve dirt
limescale
2)Seam solenoid piston dirt or
worn
1)Pressure switch failure
Repair
1)Set air combustion flap /verify correct velocity of the
burner fan/Set diesel pressure
2)Clean inside the boiler
3)Wait a few minutes
4)Verify fuel quality
1)Clean heat exchanger
2)Check/replace steam trigger gun
1)Verify and replace
2)Set correct pressure
1)Set correct pressure
2)Replace
1)Refill detergent tank
2)Replace
3)Replace (verify first connections of CN1-CN3)
4)Replace
1)Open detergent valve for air discharge
2)Replace
1)Tight solenoid valve coil
2)Clean steam solenoid valves(inside)
1)Check/clean
2)Verify/replace
with
1)Dismount/Replace
2)Replace solenoid valve piston
1)Verify pressure switch connections
