1.Check float assembly, check baffle plate
inside the water reservoir
2.Check silicone tube
1.60 DbA in 2-3 minutes is normal when water starts boiling
2.Voltage is too high
1.Use dbmeter check if it is too high
2.Check voltage is 220V or not.
1.Voltage and frequency are unstable
2.Condenser or internal parts are not well installed result
resonance
1.Check voltage and frequency
2.Hold the condenser by hand, if the noise
disappear, then put rubber pad between
condenser and side panel
1.Installation is not good

1.Probe or tube leak
2.Door switch or float switch failure
3.Transformer or Control board don’t work
4.Wire connection failure
5.Air pump doesn’t work
1.Check the probe and O rings, then reinstall
2.Check door switch and float switch
3.Check transformer(Check if the LED light
work) and control board
4.Check wire connection
1.Wrong wire connection
