Malfunction codes for Zanussi air conditioners
Zanussi air conditioners and split systems have long and firmly occupied their niche in the household appliances market in our country. The popularity of air conditioners of this brand is explained by their reliability, efficiency and successful engineering solutions. Zanussi equipment can serve without repair for quite a long time, without causing problems to its owners.
Modern household appliances are usually equipped with a self-diagnosis system. It allows you to monitor the occurrence of failures and malfunctions in the operation of equipment at the moment they occur. The self-diagnosis system is a network of sensors located on the main working components of the mechanism, and a display on which an error code is displayed when it is detected.
Error codes that occur when operating a Zanussi air conditioner can be divided into two large groups:
- errors in the external unit;
- errors in the internal unit.
The display of the error code is accompanied by blinking indicators. Each type of problem is encrypted with its own original indication combination.
Errors in the indoor unit
The internal 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 operation of the equipment. The signals are supplied by the control module, which, in turn, receives information from the sensors.
When an error occurs, the control module displays the appropriate code indicating the type of problem. In addition, the indicators on the indoor unit display panel begin to emit light signals.
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 flashes.
If there are problems 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 constant cooling mode or not cool at all.
How to proceed:
- check the condition of the sensor using a multimeter. The part may not be connected, short-circuited or open-circuited;
- if the sensor is not connected, connect or short-circuit;
- if the sensor is short-circuited, it should be replaced (full information on the location and connection of the temperature sensor can be found in the wiring diagram).
Once the problems are resolved, the error is automatically cleared.
E3 — problems with the air conditioner evaporator sensor. Accompanied by a flashing Running indicator.
The evaporator temperature sensor is responsible for timely compressor shutdown when the evaporator temperature drops to negative values. Failure of a part can lead to icing of the evaporator and its subsequent failure.
How to proceed:
- check the functionality of the part. The sensor may not be connected, short-circuited or open-circuited;
- if the part is not connected, connect or short-circuit;
- if the sensor is short-circuited, it should be replaced (full information on the location and connection of the temperature sensor can be found in the wiring diagram).
Once the problems are resolved, the error is automatically cleared.
E5 — problems with the air conditioner condenser sensor. Accompanied by a flashing defrosting indicator.
The condenser temperature sensor is responsible for regulating the refrigerant pressure in the air conditioner circuit. Failure of a part leads to incorrect operation of the equipment or its complete breakdown.
How to proceed:
- check the functionality of the part. The sensor may not be connected, short-circuited or open-circuited;
- if the sensor is not connected, connect or short-circuit;
- if the sensor is short-circuited, it should be replaced (full information on the location and connection of the temperature sensor can be found in the wiring diagram).
Once the problems are resolved, the error is automatically cleared.
F2 — malfunction of the external unit. The alarm and defrosting indicators are flashing.
The operation of the protection of the outdoor unit of the air conditioner can be influenced by several technical factors. To eliminate the error, you need to check each of them.
How to proceed:
- check the phase rotation of the supply power;
- prevent damage to pressure sensors;
- check refrigerant pressure.
Once the problems are resolved, the error is automatically cleared.
F5 — problems with the drain pan sensor. Accompanied by a flashing Alarm indicator.
A failure of the drain pan sensor leads to the pan overflowing with condensate, which in turn leads to incorrect operation of the air conditioner or split system, their damage and more complex repairs.
How to proceed:
- Check the drainage tube and clean if necessary. Sometimes just lowering the drain a little is enough;
- check the functionality of the pump;
- check the functionality of the sensor; it may not be connected, short-circuited or open;
- if necessary, connect or replace the sensor and pump.
Once the problems are resolved, the error is automatically cleared.
EI — communication error signal between externally installed unit and the internal part of the system. Accompanied by flashing Running and Defrosting indicators.
This error occurs only in some models of Zanussi brand air conditioners, for example, Zanussi ZACC. Lack of communication between blocks leads to a complete stop of the system.
How to proceed:
- check the connection of the interconnect cable;
- check the cable for breaks and damage;
- If everything is in order with the cable, check the functionality of the electronic boards of the external and internal units.
The error is not cleared automatically; after fixing the problem, you must turn off and reconnect the system power.
P6 — EEPROM error signal. At the same time, the Timer and Running indicators flash.
An EEPROM error can be either a simple failure that disappears when the equipment is rebooted, or a sign of a malfunction in 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 normally;
- If the system does not work, check the functionality of the electronic board.
The EEPROM error is not cleared automatically after the failure is eliminated; in any case, it is necessary to turn off the power to the air conditioner and turn it on again after some time.
When an error signal appears on the equipment display, the owner of the household appliance must immediately begin to fix the problem. Operating a problem air conditioner can lead to its permanent breakdown.
Errors in the external unit
Signals about errors in the operation of the outdoor unit of the Zanussi air conditioner are given by flashing LEDs on the external device board. We have compiled a complete list of problems.
Most often, in the outdoor unit of the air conditioner, the indication turns on when protection against a particular failure is triggered:
- flashes 4 times/6sec - low pressure;
- flashes 3 times/5 sec - high pressure;
- blinks 9 times/11 sec - rephasing;
- flashes 7 times/9 sec - overcurrent;
- flashes 2 times/4 sec - overheating of the external heat exchanger;
- blinks 1 time/3 sec - defrosting;
- blinks 5 times/7 sec - problems with the temperature sensor;
- blinks 8 times/10 sec - EEPROM error.
All malfunctions in the external unit of the Zanussi compressor are recorded thanks to various temperature sensors.
Temperature sensors are responsible for blocking operation in the following nodes:
- A decrease in pressure in the system is signaled by the gas main temperature sensor, which duplicates the low pressure sensor.
- When the pressure limit is exceeded, a signal is sent by the compressor discharge temperature sensor.
- The outside air temperature sensor blocks the operation of the air conditioner when the outside temperature drops below the operating range of the system provided for by the technical parameters.
As in the case of an error in the internal unit, the owner of the air conditioner should not ignore signals about problems with the external unit of the system. When a signal about a problem appears in the outdoor unit, first of all you need to pay attention to the sensors.
How to proceed:
- check the functionality of the parts. Sensors may not be connected, shorted or open;
- if the sensors are not connected, connect or short-circuit;
- if parts are short-circuited, they should be replaced (full information on the location and connection of temperature sensors can be found in the device wiring diagram);
- If no malfunctions are detected in the operation of the sensors, you should check the electronic board of the unit.7
To independently repair an air conditioner or Zanussi split system, it is not enough to know the error code and the cause of the problem. Fixing a breakdown requires the availability of professional equipment for diagnostics and repair, the possibility of purchasing original spare parts and parts for equipment of this brand.
It is also necessary to have enough free time to solve the problem. In addition, the owner of Zanussi equipment must have skills in working with household appliances, without which an attempt at self-repair is practically doomed to failure.
Unskillful attempts do-it-yourself troubleshooting may cause further damage to the equipment. The intervention of an amateur will result in expensive repairs and additional expenses. If the owner of the air conditioner is not sure that he meets all the listed conditions, it is better for him to contact the specialists of an authorized Zanussi service center.
