The LCD doesn’t
display and the
machine doesn’t
work
Bad power connection,
blown fuse, or broken
circuit
Change fuse, check the power switch, plug.
Check if plug in the rated voltage and
frequency.
The compressor
stops working
High air and water
temperature leading to
high internal pressure,
heat protector or
capacitor failure
Please improve the heat dissipation and air
ventilation. Change capacitor or heat
protector.
Refrigerating
capacity reduces
dramatically or no
refrigeration at all
after a long time of
normal use
Refrigerant leakage or
not enough refrigerant
left. Poor heat
dissipation, condenser
radiator fins blocked by
dust.
Please contact a certificated and licensed
technician to check and refill the refrigerant.
Improve the heat dissipation and air
ventilation. Remove dust accumulation on
the air inlet and parts. Reduce the water
volume referring to the specifications.
