1、the whole Troubles
Symptom 
Cause
Solution
Machine does not work,
Control panel does not show
Not connected to power
the power plug into a wall outlet

Adjust or replace micro switch
Are setting the parameter
complete parameter settings
Machine internal fault
contact the manufacturer or supplier
Vacuum chamber cover does not automatically open the
gas springs or tension springs fail
inspection, repair or replace
Can not achieve ultimate vacuum, vacuum machine is very slow
Pump running in the wrong direction
corrective steering (three phase power)
Vacuum time is set too short
to extend the vacuum time
Of oil in the vacuum pump is not enough,
Oil is not clean
check the oil level, fuel or oil (note the oil type and oil)
Pipe leak
Replacing
Pipe joints loose
checks and tight coupling.
Bag or cylinder leak
Check and tighten hoop
Leakage, seal wear
replace the seals
Oil mist filter is saturated
Replacing the oil mist filter
Can not be sealed
Or a bad seal
The bag is not properly placed above the heating plate,
the bag neatly placed on a hot plate
Sealing time is too long or too short.
Shorten or lengthen the sealing time
"Heating temperature inappropriate choice
select the appropriate heating temperature
"Damage or sticky silicone foreign body
clean-up, replacement silicone rubber
"Linoleum is damaged or a foreign body stuck
clean, replace linoleum
Inside pocket is not clean enough
clean pocket
Not inflatable
Or inflated adverse
(If there is)
Inflation time is too short or too long
to shorten or lengthen the time inflation
Cylinders are empty or nearly empty
Cylinders are empty or nearly empty
replacement cylinders
Cylinders is not open
to open the valve
Inflation pressure setting error
"Check whether the pressure gauge or secondary to an atmospheric pressure (1-AT0).
Alert! Mixed gas pressure at any time can not exceed 1 atm.
Vacuum chamber vacuum residual gas is normal but the bag is always
bad heating plate reset
Heating plate with silicone strip spacing is too large or too small
repair to the reset and flexible.
Adjust spacing.
2, the vacuum pump failure and troubleshooting
Symptom
Cause
Solution
Pump starting current or operating current is too large
Pump oil or oil overfilled wrong type
check the oil level or oil type
The temperature is low, the oil viscosity is too high
Replacing suitable vacuum pump oil
"Exhaust filter clogging
Clean or replace the filter
Pump is running when the temperature is too high
pumping too much or too little
check and adjust the oil level
Heat bad
Clean pump and motor heat sink to improve the environment ventilation.

to identify and timely repair of defective parts
Pump running in the wrong direction
corrective steering (three phase power)
Smoke or exhaust vents
Droplets
Pumping too much
let go too much pump oil
Exhaust filter installed malposition or material rupture
Reinstall or replace the exhaust filter
Exhaust filter clogging
Clean or replace the filter
3, the solenoid valve failure and troubleshooting
