Zanussi air conditioner malfunction codes
Air conditioners and split systems Zanussi have long and firmly occupied their niche in the market of household appliances in our country. The popularity of air conditioners of this brand is explained by their reliability, efficiency and good engineering solutions. Zanussi equipment is able to serve without repair for a sufficiently long period, without causing problems to its owners.
Modern household appliances are usually equipped with a self-diagnosis system. It allows you to track the occurrence of failures and malfunctions in the operation of equipment at the time of their occurrence. The self-diagnosis system is a network of sensors located on the main working units of the mechanism, and a display on which an error code is displayed when it is detected.
The self-diagnosis system of the Zanussi air conditioner, in the event of errors in operation, immediately displays their codes on the display installed on the indoor unit
Error codes that occur during the operation of the Zanussi air conditioner can be divided into two large groups:
- errors in the external block;
- errors in the indoor unit.
When the error code is displayed on the display, the indicators blink. Each type of malfunction is encrypted with its own original combination of indications.
Indoor unit errors
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.
When 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, the indicators begin to give light signals.
Error codes of the indoor unit of the air conditioner or the Zanussi split system are sent from the sensors to the control module and displayed on the built-in display of the device.
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. The Timer indicator flashes.
If there is a problem with the indoor temperature sensor, 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 with a multimeter. The part may not be connected, short-circuited or open-circuited;
- if the sensor is not connected - connect or close;
- if the sensor is short-circuited, it should be replaced (complete information on the location and connection of the temperature sensor can be found in the wiring diagram).
After fixing the problems, the error is automatically cleared.
Most of the errors of the indoor unit of Zanussi air conditioners are associated with the failure of any sensor and are automatically removed after the problem is eliminated.
E3 - problems with the air conditioner evaporator sensor. Accompanied by a flashing Running light.
The evaporator temperature sensor is responsible for the 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 breakdown.
How to proceed:
- check the functionality of the part. The sensor may not be connected, shorted or open;
- if the part is not connected - connect or close;
- if the sensor is short-circuited, it should be replaced (complete information on the location and connection of the temperature sensor can be found in the wiring diagram).
After fixing the problems, the error is automatically cleared.
E5 - problems with the air conditioner condenser sensor. Accompanied by the defrosting indicator flashing.
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 equipment or its complete breakdown.
How to proceed:
- check the functionality of the part. The sensor may not be connected, shorted or open;
- if the sensor is not connected - connect or close;
- if the sensor is short-circuited, it should be replaced (complete information on the location and connection of the temperature sensor can be found in the wiring diagram).
After fixing the problems, the error is automatically cleared.
If the indoor unit of the Zanussi air conditioner does not work correctly, you should inspect the temperature sensors located in the self-diagnosis system of the device.
F2 - malfunction of the external unit. The Defrosting and Alarm indicators are flashing.
Several technical factors can influence 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 the phase sequence of the power supply;
- eliminate damage to pressure sensors;
- check refrigerant pressure.
After fixing the problems, the error is automatically cleared.
F5 - problems with the drain pan sensor. Accompanied by a flashing Alarm lamp.
A failure of the drain pan sensor leads to an overflow of condensate in the pan, which in turn leads to incorrect operation of the air conditioner or split system, their damage and more complicated repairs.
How to proceed:
- check drain tube, clean if necessary. Sometimes it is enough to simply lower the drainage a little;
- check the performance of the pump;
- check the performance of the sensor, it may not be connected, short-circuited or open;
- if necessary, connect or replace the sensor and pump.
After fixing the problems, the error is automatically cleared.
EI - communication error signal between externally mounted unit and the interior of the system. Accompanied by the flashing of the Running and Defrosting indicators.
This error occurs only in some models of Zanussi brand air conditioners, for example, Zanussi ZACC. The lack of communication between the units leads to a complete stop of the system.
How to proceed:
- check the connection of the interconnect cable;
- check the cable for breakage and damage;
- if everything is in order with the cable, check the functionality of the electronic boards of the outdoor and indoor units.
The error is not automatically cleared; after troubleshooting, it is necessary to disconnect and reconnect the system power.
When installing the external unit of the Zanussi air conditioner, it is very important to securely connect the interconnect cable in order to avoid a failure in communication between the external and internal units.
P6 - EEPROM error signal. The start and timer indicators (Timer and Running) flash.
An EEPROM error can be either an elementary failure that disappears when the equipment is restarted, or a sign of a malfunction of the electronic board of the indoor unit.
How to proceed:
- disconnect from the network, turn on after 10 minutes. After reboot, the system will work normally;
- if the system does not work, check the functionality of the electronic board.
The EEPROM error is not removed automatically after the failure is eliminated; in any case, it is necessary to turn off the power to the air conditioner and reapply it after a while.
When an error signal appears on the display of the equipment, the owner of the household appliance should immediately take up the elimination of the problem. Operation of a problem air conditioner can lead to its permanent breakdown.
Errors in the external block
Errors in the operation of the outdoor unit of the Zanussi air conditioner are signaled by blinking LEDs on the external device board. We have compiled a complete list of problems.
Malfunctions in the outdoor unit of the Zanussi air conditioner are indicated by an indication on the electronic board using built-in LEDs
Most often, in the outdoor unit of the air conditioner, the indication turns on when the protection against a particular failure is triggered:
- blinks 4 times / 6sec - low pressure;
- blinking 3 times / 5 sec - high pressure;
- blinking 9 times / 11 sec - re-phasing;
- flashing 7 times / 9 sec - overcurrent;
- blinking 2 times / 4 sec - overheating of the external heat exchanger;
- flashing 1 time / 3 sec - defrosting;
- blinks 5 times / 7 sec - problems with the temperature sensor;
- blinking 8 times / 10 sec - EEPROM error.
All malfunctions in the external unit of the Zanussi compressor are fixed 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 line temperature sensor, which is a redundant low pressure sensor.
- Exceeding the pressure norm is signaled by the compressor discharge temperature sensor.
- The outdoor temperature sensor blocks the operation of the air conditioner when the outdoor temperature drops below the operating range of the system, provided by the technical parameters.
As in the case of an error in the indoor unit, the owner of the air conditioner should not ignore the alarm signals of the external unit of the system. When a signal appears about a malfunction in the outdoor unit, first of all, you need to pay attention to the sensors.
If there are signals about an error in the operation of the air conditioner for repair, it is recommended to contact a professional master of an authorized service.
How to proceed:
- check the functionality of the parts. Sensors may not be connected, short-circuited or open-circuited;
- if the sensors are not connected - connect or close;
- if the parts are short-circuited, they should be replaced (complete information on the location and connection of temperature sensors can be found on the wiring diagram of the device);
- if no faults are detected in the operation of the sensors, check the electronic board of the unit. 7
For self-repair of an air conditioner or Zanussi split system, it is not enough to know the error code and the cause of the problem. Elimination of a breakdown presupposes the availability of professional equipment for diagnostics and repair, the possibility of purchasing original spare parts and parts for equipment of this brand.
You also need to have enough free time to deal with 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 almost doomed to failure.
Inept attempts self-troubleshooting can cause further damage to the equipment. An amateur's intervention will result in expensive repairs and additional costs. If the owner of the air conditioner is not sure that it meets all of the listed conditions, it is better for him to contact the masters of an authorized Zanussi service center.
