Corberó dishwasher error e4

What is the breakdown of the E4 error Corbero that is affecting your dishwasher?

Hello there! If you have a Corberó dishwasher, you may have encountered the E4 error code on its display at some point. This code indicates that there is an issue with the temperature sensor of the appliance, which can affect its operation and efficiency.

But you don't have much to worry about, as this problem is highly fixable; there's no need to toss your dishwasher in the trash. Today, in this article, we'll explain what this error means, its possible causes, and how you can fix it easily and effectively.

The temperature sensor is a component that measures the water temperature entering and exiting the dishwasher, as well as that of the interior washing chamber. This information is crucial for the dishwasher to adjust the time, pressure, and water and energy consumption according to the selected wash program and the level of dish dirtiness. If this sensor fails, the dishwasher may display the E4 error code and stop functioning correctly.

Among the possible causes that can trigger the E4 error code on your Corberó dishwasher are the following:

• The temperature sensor is faulty or damaged: This can occur due to natural wear and tear from use, impact, or electrical overload.
• The temperature sensor is dirty or blocked by food residue, grease, among others: This can prevent the sensor from correctly detecting the water temperature and sending erroneous signals to the dishwasher.
• The temperature sensor is poorly connected or has a loose connection: This can happen due to incorrect installation, excessive vibration, or excessive moisture.
• The wiring or electronic PCB board of the dishwasher is damaged or burnt out: This can cause short circuits or interference that affects the sensor's operation and other components.

While all these causes may sound daunting when it comes to making a repair, the truth is it's not as complicated as it seems. Let's see what the solutions are to fix this problem.

How to fix the E4 error on the Corbero dishwasher?

We'll leave you here a list of possible solutions that you can apply to repair your dishwasher by yourself and fix the E4 error code:

1. Turn off and disconnect the dishwasher from the power supply to reset and refresh its sensors: This may help the sensor to function properly again if it's a one-time or temporary failure. To do this is extremely simple, just turn off the dishwasher completely and disconnect it from the power outlet for a few minutes. Once the time has passed (at least 5 minutes), reconnect the dishwasher, turn it on, and program a short washing cycle to check if the E4 error code has disappeared.
2. Check that the dishwasher is level and does not move or vibrate much during the washing cycle: This will prevent the sensor from shifting or disconnecting accidentally. Make sure the dishwasher is properly installed according to the manufacturer's instructions. Sometimes dishwashers are installed on irregular blocks of cement or wood, which is incorrect. The dishwasher must be installed on a firm and level floor.
3. Clean the temperature sensor with a cloth dampened in a little electronic cleaner: Locate the temperature sensor of your dishwasher and proceed to give it a little maintenance. This will remove any dirt or grease residue that may be obstructing the sensor. Make sure to leave it clean and then check if the E4 error code has disappeared.
4. Check the connections of the temperature sensor and make sure they are well adjusted and have no visible damage: Please ensure that the wiring connecting the sensor to your dishwasher is in good working condition. This wiring has to be in perfect condition, it cannot be torn, cut, burnt, scorched, melted, etc. If necessary, replace the sensor with a new one that is compatible with your dishwasher model.
5. Inspect the wiring and the dishwasher's electronic PCB board and check for any signs of burning, breakage, or corrosion: It often happens that with the steam from the water, some parts of your dishwasher can become sulfated over time and cause error codes to appear on your appliance. If necessary, replace damaged parts and/or those you believe may be affected. You can use a multimeter to assist you with this task and perform maintenance on the electronic components of your dishwasher using a good electronic cleaner.
6. If the problem persists, please repeat all the previous steps and make sure to follow everything to the letter: You may have skipped a step unintentionally, which is why we recommend repeating everything again but this time paying more attention to detail. If you still can't fix the E4 error code, it's most likely a more serious and/or complex problem that requires professional intervention.
7. Call a Corberó technical service and request a home visit for a more thorough inspection: A specialized technician can diagnose the exact cause of the error and offer you the best possible solution, whether it's repairing or replacing a part or even replacing the dishwasher with a new one if it's still under warranty. Give Corberó's technical support a call and request a home visit for a thorough inspection of your dishwasher.
