Ballu air conditioner error codes: what kind of breakdowns occur and how to repair them yourself

Air conditioners have become common climate control equipment in offices and factories, restaurants and gyms. Without them, it is impossible to imagine shopping and medical centers that admit hundreds of people every day. Split systems and mobile units are actively used in apartments and private houses to create a comfortable atmosphere and maintain a given temperature.

Air conditioners from the popular Ballu brand in Russia are often purchased for home use. Reliable equipment works throughout its entire service life, but even it sometimes fails.

You can deal with minor troubles on your own. Typically, the Ballu air conditioner displays error codes and other prompts on the display. Their decoding can be found in the manufacturer's instructions. But we will simplify the task: in this article we will tell you about ways to troubleshoot problems in models that do not provide emergency display of codes.

Classification of Ballu air conditioners

We are interested in the types of Ballu brand air conditioners for one purpose: to understand in which models’ instructions it is worth looking for error codes and in which ones not.

All modern air conditioners from the manufacturer Ballu are divided into 2 large categories:

• for home and office;
• industrial equipment.

We are only interested in less powerful models intended for home use, since industrial air conditioning is carried out by qualified engineers and technicians.

Column, cassette and ceiling-cassette split systems are more suitable for servicing office buildings, as they are designed for large areas and volumes

In everyday life, two types of air conditioners are most often used: 2-block split systems and mobile floor units.

The first type, in turn, includes inverter models.

Current DC inverter series:

• DC-Platinum Black Edition
• ECO PRO DC-Inverter
• Platinum Evolution DC inverter
• Lagoon DC inverter
• i Green Pro

Inverter modifications are convenient because you can smoothly regulate the power.

Double-block air conditioners also include air conditioners such as On/Off, current series of which:

• i Green Pro
• Bravo
• Olympio
• Lagoon
• Olympio Edge
• Vision PRO

And here's to single block models are mobile air conditioners.

This type of brand climate equipment includes the following series:

• Platinum
• Platinum Comfort
• SMART ELECTRONIC
• SMART MECHANIC
• SMART PRO

Why is it important to know this? The fact is that the instructions for any types of split systems and mobile equipment the manufacturer does not indicate error codes, but only describes malfunctions that can happen to the air conditioner. Some codes are indicated in the documentation for column air conditioners - they are listed below.

The electronic display located on the front panels informs about the air temperature indoors and outdoors, and can also show the fan speed or the selected mode. The display of errors for household models is not programmed.

Error codes and their elimination

As an example, you can read the instructions for the model Ballu MFS2-24 (AR MFS2-24 AR). It is also suitable for other air conditioners of this type.

Along with a list of faults and recommendations for their elimination, a table with codes and explanations is given. There are not many of them - we suggest you familiarize yourself with them further:

Judging by the indicated troubleshooting methods, not all faults can be dealt with on your own - you often have to contact a service center

Some craftsmen try to solve the problem on their own, but to get a positive result, you need to have a technical education and the appropriate skills.

In addition, it is better to carry out independent repairs after the warranty period has expired.

DIY fault repair

For split systems, the manufacturer has developed a short troubleshooting guide.

It does not indicate error codes, but simply lists possible breakdowns, the reasons for their occurrence and recommendations for correcting the situation.

The manufacturer categorically prohibits changing electrical wiring and making complex repairs on their own that involve replacing broken elements. For any questions please contact the technical center

All repair cases are divided into two categories:

• those that you can fix yourself;
• those that should be contacted by a service center.

Let's look at the first group in more detail.

No. 1. Split system does not turn on

If the air conditioner does not turn on, there may be several reasons:

1. Power is turned off.
2. Insufficient voltage in the electrical network.
3. Turned off circuit breaker in the electrical panel.
4. Forgot to turn on the "On" button.
5. The batteries in the remote control are dead.
6. The frequent start protection system has activated.

First, you need to check whether the air conditioner is connected to the power supply: the power plug is inserted into the socket, the power button is in the operating position.

If power is not supplied to the outlet, the machine has tripped. You can try to turn it on again yourself, but if it turns off regularly, it is better to call a technician: either there has been a serious breakdown in the unit, or the network is too weak and not designed to connect a powerful unit

If there is low voltage in the general house network or a complete power outage, you should contact Elektronadzor or the service company to clarify the situation.

If the split system does not turn on only from the control panel, simply replace the batteries. They are designed to last for a certain period of time, so it is always recommended to have a spare battery pack. Instead of batteries, you can use rechargeable batteries like AA or AAA.

When the frequent start protection system is triggered, you must wait. If the indicator lights up normally, as in operating mode, it means that after 3 minutes the air conditioner will turn on.

No. 2. The air conditioner turns on and off immediately

The next situation is that the air conditioner turns on, the compressor starts, but quickly stops working.

In this case, check whether the air access to the external unit is blocked - perhaps some foreign objects, blown by strong winds or accidentally falling from the upper floors, are blocking the grille.

When installing the external unit, follow the rules: mount it on strong brackets and protect it from debris, dust and foreign objects with a casing or grille

If everything is clean, the reason lies in the very compressor or related parts.It is forbidden to carry out diagnostics yourself; it is recommended to contact a service center.

No. 3. Problem with cooling or heating capacity

It often happens that the operation of the split system does not correspond to the specified parameters: it cools the room too little or heats the room excessively. Most often, it is not a breakdown, but rather indirect factors that prevent it from functioning effectively.

Let's look at potential causes and troubleshooting methods:

Sometimes the performance of the unit drops sharply if an additional heat source is installed in the room, for example, electric radiator.

To improve the operation of the air conditioner, the electric radiator or other heat source will have to be removed.

The reason for the violation of performance indicators can be the simultaneous presence of a large number of people in the room, which are also a kind of heat source

The normal operation of the unit may also be disrupted due to a breakdown of the defrosting system in winter. It is not recommended to repair the system yourself. You need to contact the seller or technical center.

No. 4. The fan of the internal module is broken

First, check the settings on the remote control. It happens that the wrong parameters are set by mistake and the unit refuses to work. If you use a split system for a long time, you can detect a breakdown even by a change in the noise emitted by the fan - especially if it starts to work intermittently.

The fan may not start the first time if you switch the air conditioner to heating mode. The cold air protection function is activated and blocks operation. You need to wait a few minutes, after which the fan will start working.

Review of factors that do not affect performance

Sometimes the air conditioner stops functioning, but then works normally, as if nothing had happened. Most often he requires Maintenance.

And it happens that the air conditioner makes uncharacteristic sounds that frighten the owners. Don’t rush to send it to a service center - sometimes you just need to wait it out or clean it

Let's consider situations that speak not of breakdowns, but of the operating features of the unit:

• The internal module creaks and cracks. This occurs due to the expansion or contraction of plastic parts when heated/cooled.
• Steam or “fog” is coming from under the grille of the indoor unit. This may happen if the indoor unit is dirty and requires cleaning, or after defrost mode is turned off.
• "Gurgling" sounds. An incomprehensible noise, similar to the murmur of water, causes the movement of refrigerant through the pipelines connecting the units.
• Dust flies out of the indoor module when turned on.. This happens in two cases: when starting a new unit and when turning on an old one, but after a long period of inactivity.
• An unpleasant odor appears. Remember that the split system takes air from the same room: if there is cigarette smoke or the “aroma” of new furniture (varnished parquet, painted walls), then they get inside the unit and then return back.
• Formation of condensation on the housing of the indoor unit. This happens if the humidity in the room reaches 80%. It is recommended to wipe off moisture from the plastic and normalize the humidity.
• The air conditioner runs when the fans are off. This only happens on models with a defrost mode when the heat exchanger freezes. As soon as it returns to normal, the fans turn on.

If the air conditioner spontaneously changes modes - switches from cooling or heating to ventilation mode - you should also not be alarmed. In the first case, it protects the heat exchanger from freezing, in the second, it acts to protect against overheating in order to maintain the set temperature. After correcting the problem with the Balu air conditioner, the error is reset automatically.

If you clean the system in a timely manner and refrigerant charging, you can significantly extend the life of trouble-free operation of the equipment.

Review of the split system and disassembly of the external unit:

Major home renovations are a double-edged sword. You can repair an old part, replace it with a new one and get great results.On the other hand, you can completely remove the unit from working condition, and then repairs will cost even more.

Therefore, a number of experts advise following the manufacturer’s recommendations and contacting a service center in case of any difficulty.
