9.1 Troubleshooting
Note
: if the problem identified cannot be solved using the following
guide, contact CAREL technical service.
1. Firstly, check the humidifier and the surrounding area.
Problem Cause Check Solution
No atomised water
production Power supply Humidifier switch in the OFF
position Check the switch Switch ON
No power Measure the voltage at the humidifier
input terminals Connect power
Power supply fault Measure the voltage at the power supply
output terminals Replace the power supply
Feedwater system Valve closed upstream Check Open the valve
The quantity of atomised
water is too low Power supply Low power supply voltage Check the voltage at the power supply
output terminals Replace the power supply, if
damaged
Feedwater system Water level during production
is too high and overflowing Check visually See table 2)
Other The humidifier is not installed
horizontally Check visually Adjust
No atomised water
production Dust and foreign matter accumulated in the tank (*) Clean the inside of the tank
Transducer deterioration The average life of the transducer is
around 10,000 to 15,000 operating hours Replace
The quantity of atomised
water is too low Dust and foreign matter accumulated in the tank (*) Check a view the inside of the tank Clean the inside of the tank
and replace the transducers
Scale build-up on the surface of the piezoelectric transducers (*)

(*) These malfunctions can be avoided by carrying out preventive
maintenance.
2.
If the cause has not been identified with the previous checks, there
may be faulty components. Check the inside of the humidifier.
Problem Cause Check Solution
No atomised water
production Feedwater system Float level sensor fault Empty the tank, remove the electronic board
and check continuity of the level sensor Contact service to replace the
level sensor
Float level sensor blocked Clean the sensor. If normal
operation is not restored, replace
Fill valve fault No water filled even when the tank has been
emptied Replace the valve
Clean the sensor. If normal
operation is not restored, replace
Other The fan cables are loose or
detached Check connection after removing the
humidifier cover Restore correct connection to the
terminals
The quantity of atomised
water is too low Water level overflow Float level sensor blocked If the water level in the tank reaches the
overflow pipe, remove the connector from
the control board and check continuity of the
level sensor If there is continuity, contact
service to replace the level sensor
Fill valve fault Water is filled even after switching off the
appliance Replace the fill valve
