We will also show you how to understand the combinations of indicator light signals, and what a combination of symbols on the built-in display and light signals given by indicators means. After reading the article, our readers will have information about what to do in case of a malfunction in the air conditioner or split system Zanussi.

Zanussi Air Conditioner Malfunction Codes

Air conditioners and split systems Zanussi have long and firmly occupied their niche in the home appliance market in our country. The popularity of air conditioners of this brand is explained by their reliability, efficiency and successful engineering solutions. The Zanussi equipment is able to last a long time without repair without causing problems to its owners.

Modern household appliances, as a rule, are equipped with a self-diagnosis system. It allows you to track the occurrence of failures and malfunctions in the equipment at the time of their occurrence. The self-diagnosis system is a network of sensors located on the main working nodes of the mechanism, and a display on which the error code is displayed when it is detected.

The self-diagnosis system of the Zanussi air conditioner, when errors occur, immediately displays their codes on the display installed on the indoor unit

Error codes that occur during operation of the Zanussi air conditioner can be divided into two large groups:

• errors in the external block;
• errors in the indoor unit.

The display of the error code on the display is accompanied by a flashing of indicators. Each type of problem is encrypted with its original combination of indication.

Errors in the indoor unit

The indoor unit of air conditioners and split systems of the Zanussi brand is equipped with a built-in display, which displays signals about the processes occurring during the operation of the equipment. The signals are supplied by the control module, which, in turn, receives information from the sensors.

If an error occurs, the control module displays the appropriate code indicating the type of problem. In addition, on the display panel of the indoor unit, indicators begin to emit light signals.

Error codes of the indoor unit of the air conditioner or Zanussi split system come from the sensors to the control module and are displayed on the device’s built-in display

We have compiled for our readers a complete list of errors that may occur in the internal unit of the device when operating Zanussi air conditioners.

E2 - problems with the room temperature sensor. At the same time, the timer indicator (Timer) flashes.

If there is a problem with the temperature sensor of the indoor unit, the control module does not receive reliable signals about the room temperature. As a result, the air conditioner will operate in continuous cooling mode or not at all.

How to proceed:

• check the status of the sensor with a multimeter. The part may not be connected, short-circuited or open;
• if the sensor is not connected - connect or close;
• if the sensor is short-circuited, it should be replaced (full information about the location and connection of the temperature sensor can be found on the wiring diagram).

After troubleshooting, the error is automatically resolved.

Most of the errors in the indoor unit of Zanussi air conditioners are connected with the failure of any sensor and are automatically removed after the problem

E3 - problems with the evaporator sensor of the air conditioner. It is accompanied by a flashing start indicator (Running).

The evaporator temperature sensor is responsible for timely compressor shutdown when the evaporator temperature drops to negative values. Failure of the part can lead to icing of the evaporator and its subsequent breakdown.

How to proceed:

• check the performance of the part. The sensor may not be connected, short-circuited or open;
• in case the part is not connected - connect or close;
• if the sensor is short-circuited, it should be replaced (full information about the location and connection of the temperature sensor can be found on the wiring diagram).

After troubleshooting, the error is automatically resolved.

E5 - Problems with the condenser sensor of the air conditioner. It is accompanied by a flashing defrosting indicator.

The condenser temperature sensor is responsible for regulating the refrigerant pressure in the air conditioning circuit. The failure of a part leads to incorrect operation of the equipment or its complete breakdown.

How to proceed:

• check the performance of the part. The sensor may not be connected, short-circuited or open;
• if the sensor is not connected - connect or close;
• if the sensor is short-circuited, it should be replaced (full information about the location and connection of the temperature sensor can be found on the wiring diagram).

After troubleshooting, the error is automatically resolved.

If the indoor unit of the Zanussi air conditioner is not working properly, you should inspect the temperature sensors located in the device’s self-diagnosis system

F2 - malfunction of the external unit. The alarm and defrost indicators (Defrosting and Alarm) flash.

Several technical factors can affect the operation of the protection of the outdoor unit of the air conditioner. To eliminate the error, you need to check each of them.

How to proceed:

• check phase rotation of the supply power;
• eliminate damage to pressure sensors;
• check refrigerant pressure.

After troubleshooting, the error is automatically resolved.

F5 - problems with the drain pan sensor. It is accompanied by a flashing alarm indicator (Alarm).

Failure of the drain pan sensor leads to condensate overflowing the pan, which in turn leads to incorrect operation of the air conditioner or split system, their damage and more difficult repair.

How to proceed:

• check the drain pipe, clean if necessary. Sometimes it is enough just to lower the drainage a little;
• check pump performance;
• check the operability of the sensor; it may not be connected, short-circuited or open;
• if necessary, connect or replace the sensor and pump.

After troubleshooting, the error is automatically resolved.

Ei - communication error signal between external mounted unit and the inside of the system. It is accompanied by a flashing of the start and defrost indicators (Running and Defrosting).

This error occurs only in some models of air conditioners of the Zanussi brand, for example, Zanussi ZACC. Lack of communication between the blocks leads to a complete stop of the system.

How to proceed:

• check interconnect cable connection;
• check cable for breakage and damage;
• in case everything is OK with the cable, check the operation of the electronic boards of the external and internal units.

Automatically the error is not removed, after troubleshooting, you must disconnect and reconnect the system power.

When installing the external unit of the Zanussi air conditioner, it is very important to reliably connect the interconnect cable to avoid a malfunction in the connection between the external and internal units

P6 - EEPROM error signal. At the same time, the start and timer indicators (Timer and Running) flash.

An EEPROM error can be either an elementary failure that disappears when the equipment is rebooted, or a symptom of a malfunction of the electronic board of the indoor unit.

How to proceed:

• disconnect from the network, turn on after 10 minutes. After rebooting, the system will work fine;
• If the system does not work, check the operation of the electronic board.

The EEPROM error is not automatically removed after the elimination of the failure; in any case, it is necessary to turn off the power of the air conditioner and, after some time, apply it again.

If an error signal appears on the equipment display, the owner of the household appliance should immediately take up the problem. Operation of a problematic air conditioner may result in permanent damage.

Errors in the external block

Errors in the operation of the outdoor unit of the Zanussi air conditioner are signaled by flashing LEDs on the board of the external device. We have compiled a complete list of problems.

Zanussi air conditioner outdoor unit malfunctions are indicated by an indication on the electronic board using the built-in LEDs

Most often, in the outdoor unit of the air conditioner, the indication turns on when the protection against a failure occurs:

• flashes 4 times / 6sec - low pressure;
• flashes 3 times / 5 sec - high pressure;
• flashes 9 times / 11 sec - rephasing;
• flashes 7 times / 9 sec - excess current;
• flashes 2 times / 4 sec - overheating of the external heat exchanger;
• flashes 1 time / 3 sec - defrosting;
• blinks 5 times / 7 sec - problems with the temperature sensor;
• flashes 8 times / 10 sec - EEPROM error.

All malfunctions of the external Zanussi compressor unit are detected due to various temperature sensors.

Temperature sensors are responsible for blocking operation in the following nodes:

1. The pressure sensor in the system is signaled by a gas line temperature sensor that duplicates a low pressure sensor.
2. A signal is provided about the excess of the pressure norm by the compressor discharge temperature sensor.
3. The outdoor temperature sensor blocks the operation of the air conditioner when the street temperature drops below the operating range of the system provided for by the technical parameters.

As in the case of an error in the indoor unit, the owner of the air conditioner must not ignore signals about malfunctions of the external unit of the system. When a signal appears about a malfunction in the outdoor unit, you first need to pay attention to the sensors.

If an error occurs in the operation of the air conditioner for repair, it is recommended to contact a professional authorized service master

How to proceed:

• check the performance of parts. Sensors may not be connected, short-circuited or open;
• if the sensors are not connected - connect or close;
• if the parts are short-circuited, they should be replaced (full information about the location and connection of temperature sensors can be found on the wiring diagram of the device);
• If no malfunction sensors are detected, check the electronic board of the unit. 7

To repair the air conditioner or Zanussi split system yourself, it is not enough to know the error code and the cause of the problem. The elimination of a breakdown presupposes the availability of professional equipment for diagnostics and repair, the possibility of acquiring original spare parts and parts for equipment of this brand.

You must also have enough free time to solve the problem. In addition, the owner of Zanussi equipment must have the skills to work with household appliances, without which an attempt to self-repair is almost doomed to failure.

Inept attempts self troubleshooting may cause even greater damage to equipment. The intervention of an amateur will result in costly repairs and additional costs. If the owner of the air conditioner is not sure that he meets all the above conditions, he should contact the masters of an authorized Zanussi service center.
