Error E90 Dryer Bosch

What is the fault of the E90 Bosch error affecting your dryer?

Bosch dryers are undoubtedly appliances of excellent quality and performance in terms of electricity consumption, especially in the newer models. However, dryers are not exempt from experiencing malfunctions, especially when they have not undergone proper maintenance or when events beyond our control, such as electrical supply issues, occur.

Now, is your Bosch dryer displaying the E90 error code on the screen? Then, there's no need to worry. In this article, we will explain what this error might indicate, its possible causes, and how you can easily and quickly resolve it.

The E90 error code is a fault indicating that there's a problem in the electrical system of the dryer. This can be due to various reasons, from poor electrical supply to faulty wiring. If not addressed promptly, this error can damage the dryer's electronic PCB board and lead to more severe malfunctions.

To prevent this from happening, it's important to identify the possible causes of the E90 error code and how to address them. Below is a list of the most common issues:

• Electrical supply failure: The dryer may not be receiving sufficient power to operate correctly. This could be due to a power outage, a faulty plug or outlet, or a blown fuse.
• Damaged electrical wiring: It's possible that one of the cables connecting the dryer to the electrical grid is broken, loose, burned, or scorched. This can lead to short circuits or loose connections that hinder the normal operation of the dryer.
• Loose or damaged terminals or connectors: One of the terminals or connectors connecting the cables to the electronic PCB board of the dryer may be loose, damaged, or improperly placed. This can result in poor communication between the electrical components of the dryer, causing the E90 error code.
• Blown fuses: One of the fuses protecting the electronic PCB board of the dryer may have blown due to overload or a short circuit. This can prevent the board from receiving the proper signal to control the operation of the dryer.

How to fix the E90 error on the Bosch dryer?

Now that you know what are the possible causes that can cause error code E90 to appear on your Bosch dryer, we show you how you will be able to solve this problem on your own:

1. Restart your dryer to reset the sensors: Sometimes electrical supply issues can confuse your dryer's sensors, so we'll reset it to get these sensors back to their normal state. To do this, the first thing you need to do is disconnect the dryer from the electrical outlet for a few minutes and then reconnect it. Now turn it on and check if the error code has disappeared.
2. Check the electrical supply for your dryer: You need to ensure that the dryer is receiving the proper power to operate. Refer to the manufacturer's manual, and once you have this information, thoroughly inspect your home's electrical supply and the outlet where your dryer is connected. If you don't have the manual on hand, you can try connecting the dryer to another electrical outlet in your home. Remember that each outlet has an amperage limit, so we recommend keeping a dedicated outlet for your dryer and disconnecting all other devices or appliances sharing the same connection.
3. Inspect the electrical wiring reaching your dryer: Examine the condition of the cables connecting the dryer to the electrical grid. If you see any cables that are broken, loose, burned, scorched, or in very poor condition, you'll need to replace or repair them as soon as possible. This wiring must be in perfect condition, without exception.
4. Check the terminals and connectors of the electrical wiring on your dryer: Verify that the terminals and connectors connecting the cables to the electronic PCB board of the dryer are properly tightened and positioned. If you notice any loose or improperly placed terminals or connectors, you should tighten or position them correctly.
5. Check the fuses of your dryer: Ensure that the fuses protecting the electronic PCB board of the dryer are not blown. If you see any blown fuses, you'll need to replace them with new ones of the same amperage.
6. Repeat all the previous steps if the problem persists: If after performing all these checks, the E90 error code continues to appear on the screen, you should repeat all the previous steps to make sure nothing has been overlooked. A second check wouldn't hurt, but if the problem persists, it might be time to call in the professionals.
7. Give a call to Bosch technical support to resolve the issue: If after repeating all the previous steps, the E90 error code remains unresolved, you should contact Bosch's official technical service so that a professional can inspect your dryer and provide a definitive solution.

In summary, the E90 error code in Bosch dryers is an electrical fault that can have various causes and solutions. Among the most common causes that can lead to this fault, it could be an electrical supply failure, damaged electrical wiring, loose or improperly placed terminals, or blown fuses. To resolve it, you can follow the steps outlined below:

• Restart your dryer to reset the sensors
• Check the electrical supply for your dryer
• Inspect the electrical wiring reaching your dryer
• Check the terminals and connectors of the electrical wiring on your dryer
• Check the fuses of your dryer
