In case of failure, please carry out inspection according to the requirements below.
If unresolved, please contact the local service agency.
Failure Cause Solution
Low water flow
Low water pressure Check the booster pump
or water inlet
Filter not replaced in time,
beyond the use time
Please contact the local service
agency to replace the filter
Unsuitable water
temperature
Over consumption of water
in a short time
Just wait a moment, and water
is available again
Power supply not put through Switch on power supply
Corresponding functions not
started
Press a corresponding function
key to start the function
Pipe not connected properly Inspect the connector to
connect the pipe properly
Water leakage
Water pipe and PE pipe
bursting Replace the water pipe and PE pipe
light flashing There might be a leakage
Check the PCB on the base plate.
Repair the machine and dry the
PCB, and then power on again.
Electrical leakage Machine in poor contact
with ground
Use a three-pin socket with
earth wire, making the machine
grounded properly
Noisy operation Not installed properly Place the machine on a steady
& solid surface
Machine fails to run Check the power supply Switch on power supply
It is a normal state that the following circumstances occur when the water purifier is used.
1. During the heating, the heating tube may generate slight noises. This is a normal state.
2. When the heating tank is being heated without water, the anti dry-burning device will
disconnect automatically and can not reset by its own. The reset must be completed by a
professional technician. The design is in accordance with the national safety requirements.
3. When an ambient temperature is higher, the cooling capacity may be slower, which is a
normal state.
