Zanussi Fridge-Freezer Error Codes and How to Resolve Them

When a Zanussi fridge freezer encounters a fault, an error code appears on its display panel. Each specific code indicates which part of the appliance is experiencing a problem. This article examines these Zanussi error codes, their causes, and the necessary steps to resolve them. Read on for a comprehensive guide.

List of Zanussi Fridge Freezer Error Codes and Their Solutions

This section details the error codes listed above. Each code points to a fault in a specific part of the appliance. Understanding them helps you know precisely what actions to take to resolve the issue when it arises.

1. Error: Normal – SH

Cause: The reason for encountering the Normal – SH error on a Zanussi fridge freezer is the detection of a short circuit in the fresh food compartment (fridge) sensor.

Solution: To resolve the Normal – SH error code, you must inspect the fridge sensor and locate the short circuit in its wiring. If necessary, repair or replace the sensor's connections. If you suspect the sensor itself is faulty, consider replacing it.

2. Error: Normal – OP

Cause: The primary reason for displaying the Normal – OP error code is an open circuit in the appliance's sensor, which the auto-diagnostic system indicates with this error.

Solution: To fix the Normal – OP error, go to the fresh food sensor and its connections, and carefully examine all wires connected to it. Wherever you find an open circuit, replace the faulty wire and check the fridge freezer's operation again.

3. Error: E0

Cause: The reason for encountering the E0 error code is that the appliance has detected no fault and reports all systems are functioning correctly.

Solution: If you are looking for a solution to clear the E0 error, you should know this code does not indicate a malfunction. It informs us that the appliance is not facing any error.

4. Error: E1

Cause: The main reason for displaying the E1 error is the detection of a faulty evaporator sensor.

Solution: To resolve the E1 error code, first measure the resistance of the evaporator sensor to ensure it is healthy. Check the wiring connected to this sensor and, if you observe the slightest fault in any of them, replace the defective wire or the faulty sensor.

5. Error: E2

Cause: We encounter the E2 error code because the room temperature sensor is damaged. (The sensor is installed on the power board.)

Solution: To fix the issue related to the E2 error, check the function of the room temperature sensor along with its related connections and ensure they are working correctly. Replace all faulty connections and even the defective sensor, then check the appliance's operation again. If you cannot resolve the E2 error yourself, contact an authorised and reputable Zanussi fridge freezer repair centre.

6. Error: E4

Cause: The reason for encountering the E4 error is a defect or fault in the room temperature sensor at its connection point to the main board.

Solution: The appropriate method to resolve the E4 error is to check the connections and wiring of the appliance's room temperature sensor at the electronic board location. Any fault observed in the connections of this section must be repaired. Replace damaged wires and check again for the display of the E4 error code.

7. Error: E5

Cause: The most important reason for displaying the E5 error is a faulty zero-degree compartment sensor. The sensor may have failed, or one of its connections or wiring may be damaged.

Solution: A good solution to address the E5 error is to inspect the zero-degree compartment sensor and find its faults. If you encounter an issue with the sensor's connections, replace the faulty connections and wiring as soon as possible. Finally, if you see the fault is with the sensor itself, proceed to replace it.

8. Error: ER

Cause: The display of the ER error code is related to faulty connections on the ice maker board. This problem in the Zanussi fridge freezer is communicated to the user with the ER error.

Solution: If you are looking for a way to fix the ER error, carefully examine connectors J4-4, J4-5, and J4-6 on the ice maker board. Check that connector J4 on the main board is intact. Then, on the main board, go to the row of 15-pin connectors and test them. If all connections and connectors appear healthy, replace the control board.

9. Error: T3

Cause: The problem that leads to the display of the T3 error code is related to a short circuit or open circuit in the temperature and humidity sensor.

Solution: To resolve the T3 error at home, you must be able to access the humidity sensor location and examine the wires connected to it. Look for the location of a short circuit or open circuit in the appliance's wiring and, if observed, replace them. The faulty sensor may need repair or even replacement. For this reason, it is better to contact a specialised repair centre like Dareh Chareh to resolve the T3 error.

10. Error: SY – EF

Cause: We face the SY – EF error when the evaporator fan has failed and is faulty.

Solution: The only solution to clear the SY – EF error code is to inspect the evaporator fan, its connections, and its blades. Examine the connections meticulously and replace those that have short-circuited or completely broken. Then, check that nothing is stuck between the fan blades. If the SY – EF error persists, contact the Dareh Chareh home appliance service and repair centre for specialised repair of the appliance.

11. Error: SY – CF

Cause: The important reason for encountering the SY – CF error is that communication establishment between the boards has not been successful.

Solution: To resolve the SY – CF error code, you must be able to check the communications between the boards and find the cause of the failed connection. The connections or wiring between the boards and components may need replacement.

12. Error: SY – CE

Cause: The reason that leads to the display of the SY – CE error is a communication error between the appliance's boards (main board and display), which the auto-diagnostic system warns us about by showing this error.

Solution: The appropriate method to resolve the SY – CE error is to check all connections and communications between the electronic board and the display board. If you observe faulty or broken connections on any of them, promptly proceed to repair the faulty location.

13. Error: OP – Normal

Cause: The reason for displaying the OP – Normal error is the detection of an open circuit in the freezer sensor.

Solution: To clear the OP – Normal error code, first carefully examine the freezer sensor and all its connections to find the cause of the power cut to the sensor and the location of the open circuit. Repair and, if necessary, replace the faulty and non-functioning wires.

14. Error: SH – Normal

Cause: The main reason you have encountered the SH – Normal error code relates to a short circuit in the freezer sensor.

Solution: To resolve the SH – Normal error, first unplug the appliance, then go to the connections and wiring of the freezer sensor and ensure they are all healthy. If you are unable to diagnose the SH – Normal error on your own, contact the Dareh Chareh repair centre.

Troubleshooting Zanussi Fridge Freezer Errors

After familiarising yourself with the error codes, this section covers the tips and tricks for troubleshooting this appliance when the auto-diagnostic system has been unable to locate the fault. In these situations, before seeking help from customer service centres, we recommend trying the instructions provided in this section.

1. The Zanussi Fridge Freezer Has No Power

Cause: The lack of power to the Zanussi fridge freezer can be related to several issues. Some of these are as follows:

• The socket in use may have no power.
• The household electricity may be cut off.
• The fuse in use may be blown or faulty.
• The thermostat control knob may be set to "0".

Solution: To resolve the no-power issue, check the following:

• Check the socket the plug is connected to and ensure it has power. Test other sockets.
• Make sure the house electricity is connected.
• Check the fuse and replace it if it is faulty or blown.
• Check the thermostat settings.

2. Fridge or Freezer Compartment Temperature is Too High

Cause: When you face the problem of high temperature in the fridge or freezer of your Zanussi appliance, two possibilities exist. Either the fridge freezer is placed in a very hot environment, or the thermostat control knob is set to a very low number. Note that this issue is not indicated by any of the Zanussi error codes.

Solution: If you are looking for a way to solve the problem of high temperature in the fridge or freezer, check that the ambient temperature around the appliance is between 10°C and 32°C. Then, adjust the thermostat settings according to the ambient temperature and set it to an appropriate level.

3. The Zanussi Fridge Freezer Compressor Runs Non-Stop

Cause: We face the issue of the compressor running continuously when one of the following has occurred:

• The thermostat control knob is set to the wrong temperature.
• The appliance door is open.
• A large volume of fresh food has been put in at once.
• The door has been opened and closed many times during the day.
• The arrangement of food and containers inside is blocking the ventilation vents.

Solution: The most important available solutions to solve the non-stop running issue are as follows:

• Readjust the thermostat control knob.
• Close the appliance door and only open it when necessary.
• Rearrange the food and containers inside the compartment.

4. Fridge or Freezer Compartment Temperature is Too Low

Cause: The primary cause leading to excessively low temperature in the fridge or freezer compartment is related to the appliance's thermostat settings being on a cold setting and is not related to error codes.

Solution: To fix the problem of excessively low temperature, simply change the thermostat settings and set it to a warmer state.

5. Frost or Ice Build-Up is Observed on Internal Walls and Surfaces

Cause: We face frost and ice build-up on the internal walls when one of the following has happened:

• The temperature and humidity around the appliance are excessively high.
• The appliance doors are left open for long periods.
• The rubber door seal is dirty or damaged.
• You have placed food in unpackaged or open containers inside.

Solution: To resolve the frost and ice build-up issue, try not to open the fridge or freezer door unnecessarily and close it immediately after use. Also, always pour watery foods into sealed containers before storing them in the fridge. Check that nothing is preventing the door from closing, and finally, inspect the rubber door seal carefully. If you observe the smallest gap that allows air exchange, promptly replace this part.

6. The Zanussi Fridge Freezer is Very Noisy

Cause: The most important reason for a noisy fridge freezer is the appliance not being level on the floor or it touching the surrounding walls or cabinets, and is not related to error codes.

Solution: To solve the noise problem, the only thing you can do is check the surface under the appliance and ensure it is flat and level. Also, check that the appliance is not in contact with walls or items placed around it. Note that some of these sounds are completely natural and related to the appliance's normal operation, such as:

• A bubbling or gurgling sound heard when refrigerant is pumped through the pipes.
• A humming or buzzing sound heard when the refrigerant is pumped while the compressor is on.
• A slight clicking sound heard when the thermostat controls the compressor temperature.

Required Actions Regarding Food After Power is Restored

Whenever the household electricity cuts off suddenly, try not to open the freezer door while the power is off to preserve the cold inside. If frozen food items have thawed, follow these instructions for re-freezing them:

• Ice Cream: Once thawed, it should be discarded.
• Fruits and Vegetables: If soft, cook and consume them.
• Bread and Cake: Can be frozen again.
• Cooked Foods: Should be kept in the fridge and consumed promptly.
• Large Meat Cuts: Can be re-frozen, provided ice crystals are still present on the meat tissue.
• Poultry: Should be cooked and then frozen.
