Gurgling noise

A gurgling noise can be caused by two different issues.

Is the machine new out of the box or only been used a couple of times?

New out of the box

Used a couple of times

Reference code:

Out of the box

This can usually be resolved by running approximately 2 to 4 tanks of water through the machine when in Humidifier mode.

Has running the machine with two - four tanks of water resolved the problem?

Reference code:

Machine settling

This may be caused by the machine settling and will pass with time.

How many full tanks of water have been put through the machine?

Four tanks or less

More than four full tanks

Reference code:

No fault with the machine

There is no fault with the machine, the noise can sometimes be heard when the ultrasonic transducer produces mist inside the base of your machine.

This noise is most noticeable when the machine is new, but the noise will reduce in volume once approximately 3-4 full tanks of water have been run through the machine.
