11.1 Troubleshooting

NOTICE:
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
No atomised water Power supply
production
Feedwater system
The quantity of atomised Power supply
water is too low
Feedwater system
Other
No atomised water Dust and foreign matter accumulated in the tank (*)
Transducer deterioration
production
The quantity of atomised Dust and foreign matter accumulated in the tank (*)
Scale build-up on the surface of the piezoelectric transducers (*)
water is too low
(*) 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
No atomised water Feedwater system
production
Other
The quantity of atomised Water level overflow
water is too low
Direct version for room applic. +0300062EE - rel. 1.4 - 24.09.2020
Humidifier switch in the OFF position
No power
Power supply fault
Valve closed upstream
Low power supply voltage
Water level during production is too
high and overflowing
The humidifier is not installed
horizontally
Verification
Float level sensor fault Empty the tank, remove the
electronic board and check
Float level sensor blocked
continuity of the level sensor
Fill valve fault No water filled even when the tank
has been emptied
The fan cables are loose or Check connection after removing
detached the humidifier cover
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
Fill valve fault Water is filled even after switching
off the appliance

Verification
Check the switch
Measure the voltage at the
humidifier input terminals
Measure the voltage at the power
supply output terminals
Check
Check the voltage at the power
supply output terminals
Check visually
Check visually
The average life of the transducer is
around 10,000 to 15,000 operating
hours
Visually check the inside of the tank Clean the inside of the tank
Solution
Contact service to replace the level
sensor
Clean the sensor. If normal
operation is not restored, replace
Replace the valve
Clean the sensor. If normal
operation is not restored, replace
Restore correct connection to the
terminals
If there is continuity, contact service
to replace the level sensor
Replace the fill valve
Solution
Switch ON
Connect power
Replace the power supply
Open the valve
Replace the power supply, if
damaged
