A household humidifier, subject to operating rules, allows you to create the optimal microclimate in the living room. But with it, as with any other equipment, problems can arise, including leaks and so on. We noticed a puddle next to a working device and do not know what to do if a humidifier is leaking and can this problem be fixed on its own? Or is it better to contact a service center?

We will help to deal with these issues - in our article, we consider the possible causes of leaks and provides step-by-step instructions for identifying the location of the malfunction. We will also talk about what should be done to eliminate the breakdown, and in which case it will be more practical and cheaper to purchase a new humidifier.

Safety measures for repairing the humidifier

An air humidifier is an electrical device, and the interaction of electricity and moisture can lead to negative consequences such as electric shock or short circuit (short circuit). And the short circuit can not only permanently disable the climate device, but also cause a fire.

Therefore, when identifying leaks, first of all, it is necessary to take care of safety measures.

Why should:

  • disconnect the device;
  • pour out the remaining water.

The last point must be performed so that the liquid does not get on the control board or any other electrical component during self-troubleshooting.

If signs of leakage of the humidifier are detected, then the first thing to do is to turn off the power to the appliance. This will provide the user with security.

Leak Detection Tutorial

A problem such as water leakage from a humidifier can occur due to various reasons.

In order to identify a malfunction with minimal time and money, and eliminate it, you should perform a series of actions by checking:

  • correct assembly of the unit;
  • warranty validity;
  • structural integrity;
  • check the operability of electronics and other structural elements that ensure atomization.

Since the operability of an air humidifier that drips may depend on each of the listed actions, you should familiarize yourself with them in more detail - this will facilitate an effective troubleshooting and allow you to make the right decision.

Leak elimination
Identification of the causes of failure should begin with the simplest procedures and gradually move on to more complex ones. Since such a method will provide almond time

Step # 1 - verify the assembly

The design of any humidifier has rubber elements. Namely gaskets cases, filters, valves. They are designed to prevent leakage, transfusion of fluid.

But it happens that these parts are not installed correctly, for example, after replacing the filter or disassembling the housing for cleaning and maintenance. This leads to a violation of the tightness of the structure and loss of performance.

The described cause of leakage is common and easily eliminated even at home. Therefore, repairs should always begin with a leak test. Especially when the malfunction manifested itself after performing any manipulations with the humidifier.

Many models begin to flow if the filter is not tightly screwed. If the humidifier has been used for many years, then the leakage may indicate that the service life of the rubber structural elements has ended and should be updated. What technically can be done simply and inexpensively, but there may be a problem with finding the right gaskets.

And yet, in most cases, the problem will be fixed quickly, for which you just need to perform the correct assembly of the humidifier.

Visual inspection of the humidifier
An effective way to identify the causes of leakage is to carry out a routine visual inspection of the humidifier. Which will help identify a problem with improper assembly of the product, damage to the seals.

Sometimes distortions and deformations that cause leakage are caused by the installation of the unit on an uneven surface. All that is needed in this case is to use a horizontal and solid support.

We recommend that you read the recommendations for choosing the right humidifier placement.

Step # 2 - clarifying the warranty period

If, following the steps listed in the previous section of the article, it is not possible to achieve the desired result, you should interrupt the search for the cause of leakage and remember when the purchase was made.

If it was relatively recently, then you should find the documents attached to the humidifier and see if the warranty applies to it.

If so, then there is no need to spend time independently searching for a malfunction and you just need to turn in the leaking unit:

  • to retail outletwhich made the sale;
  • to the manufacturer’s service center, whose specialists will be able to perform high-quality repairs or return the funds spent on the purchase of a humidifier.

If you still have the opportunity, you should definitely use the guarantee provided by the manufacturer. Since this is the easiest and most effective way to avoid financial losses and time costs.

A significant drawback of contacting a service center is the long repair period - sometimes you have to wait for the right part for months.

Step # 3 - search for mechanical damage

Often, the cause of the humidifier is leaking, cracks, chips and other damage that occur on the body as a result of mechanical damage.Namely, with falls, bumps and any other critical loads.

Humidifier drops
Humidifier housings are usually made from inexpensive types of plastic. Which can receive this or that damage at mechanical stresses, for example, from blow. And the older the product, the higher this probability

In these cases, to identify the cause of leakage of the humidifier is simple. For which it is usually sufficient to perform a visual inspection of the product body.

Eliminate leakage by replacing a failed structural element. But it should be understood that repair is not always advisable because of its high cost. Since it is often necessary to restore the large parts of the housing, namely its lower or upper part, to restore the humidifier’s performance.

If the damage area is insignificant, then you can try sticking a plastic patch over the crack if it does not interfere with the assembly, functioning of the parts and components of the humidifier.

Sometimes leakage is caused by damage or wear to the exhaust pipe. It is also easy to identify, but again, the feasibility of repair in this case is doubtful due to the high cost of the spare part.

Step # 4 - checking electronics and mechanics

The study of the condition of the interior of the humidifier should begin with those structural elements whose damage can be detected visually.

These include:

  • water seal;
  • distribution head for air supply.

Such a detail as gate often clogged. This leads to the fact that the liquid is squeezed out of the body of the product through any nearby holes.

In the foreground is a fan snail. Incorrect settings can cause moisture to spill out of the humidifier tank. Above left is a membrane, or rather its casing (diamond-shaped, golden in color with a hole in the middle of the structure). Failure of the specified element will also lead to the appearance of wet spots around the climate device

Distribution head allows you to adjust the air pressure. Since excessive performance or high air velocity leads to the fact that part of the water splashes. In this case, simply adjust the humidifier.

But it happens that she wears out or fails for other reasons. Therefore, it is possible to eliminate the malfunction only by replacing the distribution head, and sometimes the fan.

Humidifier Maintenance
Reduces the likelihood of leakage, and significantly, regular maintenance of the humidifier. The main procedure of which is cleaning the device

In construction ultrasonic humidifiers There is a mechanism called a membrane. Its task is to split water into the smallest particles. But sometimes the membrane (piezoelectric element) fails, which is easy to determine by the absence of a characteristic “gurgling” during the operation of the device. As a result, the fan blows out of the case not steam, but a drop of water, which leads to the formation of puddles of water around the unit.

These problems are resolved by replacing the part. But, if replacing the piezoelectric element (even on its own) is quite simple, drinking old and soldering a new one, then there may be difficulties in finding the right one.

In addition to leaks with a humidifier, other problems can occur. Therefore, we recommend that you familiarize yourself with most popular faults and how to repair them.

Conclusions and useful video on the topic

The video below explains how to replace the membrane yourself. And most importantly, this material will allow you to get acquainted with the design of humidifiers and how to disassemble it. Which will simplify the task of finding and eliminating the causes of leakage:

Finding out why your humidifier is leaking is relatively easy even at home.But it should be understood that a person who first encountered this problem can take a lot of time to solve it. Sometimes it happens that repairing a product is unprofitable - it's easier buy a new humidifier.
