9.1 Troubleshooting

Note
: if the problem identifi ed cannot be solved using the following
guide, contact CAREL technical service.
1. Firstly, check the humidifi er 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 identifi ed with the previous checks, there
may be faulty components. Check the inside of the humidifi er.
Problem Cause
No atomised water Feedwater system
production
Other
The quantity of atomised Water level overfl ow
water is too low
Direct version for room applic. +0300062IE - rel. 1.0 - 10.09.2015
Humidifi er 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 overfl owing
The humidifi er is not installed
horizontally
Check
Float level sensor fault Empty the tank, remove the electronic board
and check continuity of the level sensor
Float level sensor blocked
Fill valve fault No water fi lled even when the tank has been
emptied
The fan cables are loose or Check connection after removing the
detached humidifi er cover
Float level sensor blocked If the water level in the tank reaches the
overfl ow pipe, remove the connector from
the control board and check continuity of the
level sensor
Fill valve fault Water is fi lled even after switching off the
appliance

Check
Check the switch
Measure the voltage at the humidifi er
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
Check a view the inside of the tank
Solution
Switch ON
Connect power
Replace the power supply
Open the valve
Replace the power supply, if
damaged
See table 2)
Adjust
Clean the inside of the tank
