Trouble shooting
The machine
can’t be started.
Refrigerating
fails
The machine
keeps powering
‘ƒ†‘ơ
repeatedly after
standby
Small or no pure
water output
The high pressure
pump works
normally but no
water is produced
Power supply is not connected
Refrigerating system is not powered on
No water or low-level water in pure
water tank
Refrigerant leakage
Machine vibrates. water level in the
tank is not stable. High and low level
