POSSIBLE CAUSE

No voltage in pressure switch
Disconnected winding of motor, damaged
thermal protection
Faulty capacitor
Seizure of piston or another rotary part
Pressure switch does not switch on
Air leak in pneumatic distribution system
Leaking check valve
Greater volume of condensed liquid in
pressure vessel
of Air leak in pneumatic distribution system
Worn piston ring
Contaminated input filter
Contaminated filter in dryer
Defective solenoid valve
Damaged bearing of piston, piston rod,
motor bearing
Loose or cracked spring
No voltage in suction unit clamp
Exhauster overheating
(thermal protection switched off)
Suction line leaking, foreign object
trapped in suction piping, blocked
exhaust line
Corrupted ( long-time running at the low
pressure, age) or very polluted drying
refill
Check voltage in socket
Check fuse – replace faulty one
Loosen terminal – tighten it
Check power cord – replace faulty
one
Replace motor or re-wind it
Replace capacitor
Replace damaged parts
Check the function of pressure
switch
Check
system – seal loose joint
Clean
replace valve
Drain condensed liquid
Check
system – seal loose joint
Replace worn piston ring
Replace the contaminated filter
with a new one
Replace the output filter in a
chamber or also its refill if it gets
decomposed or if it is very dusty
Repair or change the valve
Replace damaged bearing
Replace damaged spring
Check voltage in the socket
Check fuse
Loose clamp – tighten
Check the power cord
Methodically test the wiring circuit
The check of functionality of
housing ventilator – replace the
non-functioning one
Check of the clearness of
sucking and exhausting tract -
(remedy hose cranks and
remove foreign objects)
Check/replace damaged suction
line, check/clear suction line of
foreign objects, unblock exhaust
line
Replace drying refill and filters
