Faults
Reasons
Troubleshooting
1
No vacuum or
the indication
of the vacuum
gauge is
inaccurate
1. Low motor speed or low voltage
Check whether the voltage is stable
2. Vacuum bottle and check valve are
clogged or corroded by dirt
Clean up the internal dirt or replace with a
new bottle and valve core
3. The water inlet and filter tube are
blocked
Cleaning, taking out the internal dirt
4. The impeller fell off
Replace the impeller
5. Water or air leakage in the vacuum
gauge
Clear out the water in the watch, reset the
hands to zero or replace the watch with a
new one
6. The vacuum pipeline is blocked or the
tube is cracked
Clean the pipeline or replace it with a new
one
2
Motor not
working
1. The fuse is blown
Replace with a new fuse
2. The running capacitor is broken down
Replace with a new capacitor with the
same voltage as the original capacitor
3. The motor winding is burnt out
Replace with new motor
4. The bearing is severely worn and stuck
Replace with new bearing
5. The impeller is blocked and stuck
Clean up sundries and correct impeller
position
6. False soldering of the line end or
loosening of the line card
Welding firmly and clamping tightly the
line card
3
The motor
heats up and
makes too
much noise
1. Bearing wear
Replace with new bearing
2. Impeller wear and deformation
replace the impeller with a new one
3. The voltage is unstable or the voltage is
too low
Check whether the line is overloaded and
whether there is low voltage phenomenon
4
The water in
the tank is
fluctuating
1. The drainage direction of the filter pipe is
incorrect
Adjust the drainage direction
2. The water level is too low
Add water until the water level reaches the
overflow
5
Water leakage
1. The overflow nozzle of the water tank is
loose or the sealing ring is aging
Tighten the nozzle or replace the sealing
ring
2. The water tank is broken
Replace the water tank
