Bosch household appliances are popular among users, but not a single device is insured against breakage. Therefore, if an error code is displayed on the Bosch refrigerator, you need to decrypt it. Its value will indicate to you the element that failed. So you can diagnose and repair the part.
Error codes for Bosch refrigerators
You habitually operate the refrigerator, and suddenly on the display you notice symbols. On some models, indicators may blink or a beep may sound. Before you start looking for damage, eliminate a system failure. For this:
- Unplug the refrigerator.
- Wait 10-15 minutes.
- Run it again.
Look at the screen. If the code disappeared, then the cause was a system failure. If not, then look for a transcript in the instructions or our table.
Malfunction code | What does it mean | Do-it-yourself troubleshooting |
E1 / r1 | The temperature sensor in the refrigerator compartment has failed. | Check the sensor, its contacts and wiring. Tighten the connections, replace the ribbon cable or part. |
E2 | The evaporator sensor in the refrigerator is defective. | In this case, the temperature in the chamber may increase, and ice and snow form on the walls. Run diagnostics and install a new sensor. |
E3 / F1 | The temperature sensor in the freezer does not give a signal. | The sensor informs the control board about the temperature in the chamber, after which the compressor switches off. Therefore, in the event of a breakdown, the element should be urgently replaced. |
E4 | Error E4 reports that the condenser sensor in the freezer is broken. | Inspection of connections and performance checks. Repairs. |
RT | The electronic module does not work correctly. One of its elements is defective. | Need a diagnosis of the module, the continuity of parts with a multimeter. A visual inspection will help determine the location of the burnout. Repair is best entrusted to a specialist. |
d1 | The sensor on the rib is out of order. | Testing the control module and replacing the sensor. |
Dr | The door open sensor has triggered. Probable reasons include:
| What can be done:
|
dF | The door open and close switch in the freezer does not work. | Open and close the door again. Check switch connections, install new part. With prolonged use, the key is buried or stuck in the slot. Therefore, the module cannot determine whether the door is open or not. |
Ef | The flow sensor or solenoid valve does not function. | Diagnose and repair the malfunction. |
Et | The horizontal switch does not work. | Switch replacement required. |
The EU | The on / off key is stuck. | Inspect the key. If it is sunken or stuck, install a new element. |
ES | The ice / water shift lever does not work. | Diagnostics of contacts, wiring and the lever itself. |
Ea | The freezer compartment motor does not work. | It is necessary to check the engine for efficiency. In the absence of signs of "life" is a replacement. |
Eg | The inlet valve does not work. | This is probably a valve that lets water into the ice maker. If the latter is provided in your model, then inspect the valve. |
Signs that portend a breakdown or indicate a malfunction in Bosch refrigeration:
- The compressor is constantly working, without a break for rest. The temperature in the compartment does not reach normal, ice and snow may form on the walls. Check the rubber seal, the position of the thermostat. The temperature may be set too low.
Remember, you do not need to set the relay to maximum, even if the room is hot. If the device is correctly selected, it will cope with the load. See if Super Freeze is on. In mechanical models, it is turned off manually: you may have forgotten to turn it off.
- The compressor does not start, while the light in the compartment is on, which indicates the presence of voltage in the network. In addition, clicks may be heard. This means that the start-up relay is trying to start the motor. It can turn on, but immediately turns off. Conclusion: compressor wear. Urgent replacement.
- Noise is heard during operation of the unit, although this has not happened before. If abnormal sounds are heard while the refrigerator is operating, the cause may be motor wear. Also, his mounts could be loosened, so you need to tighten them. In models with Nou Frost, a fan may make a noise if the blades are covered with ice. Then a defrost of at least 10 hours is required.
- Snow is growing on the walls of the department. There can be many reasons: the seal was torn, the thermostat broke, problems arose with the evaporator or its parts. Full diagnostics required.
- The temperature in the chamber is optimal, but the compressor continues to work. The thermal switch may have broken, a refrigerant leak, or a clogged capillary tube. The most difficult thing is the breakdown of the electronic module.
