Siemens Dryer Error e09

What does this failure affect Siemens dryers?

Siemens brand dryers are appliances of excellent quality and performance in terms of electricity consumption, especially in newer models. Siemens is a partner brand of Bosch, so if you have a dryer from either of these two brands, you can be sure that you have an appliance that combines the best of both.

Dryers are not invincible, as like any electronic device, they can have malfunctions in their operation, especially when they have not been given proper maintenance or when there are issues with the power supply.

The E09 error code failure in Siemens dryers is a fault that indicates a problem in the dryer's electrical system. And we haven't made it up, as the Bosch website itself indicates that the problem is indeed an electrical fault. This problem can be due to several reasons, from faults in the power supply to damaged electrical wiring.

Below is a list of the most common causes of this problem that appears on your dryer:

• Power supply failure: It may be that the dryer is not receiving enough power to operate correctly. This could be due to a power outage, a defective plug or outlet, or a blown fuse.
• Damage to electrical wiring: It may be that one of the wires connecting the dryer to the electrical network is broken, loose, or burnt. This can cause short circuits or false contacts that prevent the dryer from functioning normally.
• Loose or damaged terminals or connectors: It may be that one of the terminals or connectors that connect the wires to the electronic board or components of the dryer is loose, damaged, or improperly placed. This can cause poor communication between components and lead to malfunctions like the one you are experiencing.
• Blown fuses: It may be that one of the fuses protecting the dryer's PCB electronic board has blown due to overload or a short circuit. This can prevent the board from receiving the proper signal to control the dryer's operation.

All of these causes are what can trigger this error to be displayed on the screen of your Siemens dryer. But you don't have much to worry about because in this article, we will show you the solutions you can apply to fix this problem.

How can the E09 error of the Siemens dryer be fixed?

To continue using your Siemens dryer normally, you would need to follow the following steps we are going to leave for you below. Let's try to revive that dryer!

1. Reset the Siemens dryer to reset the sensors: Sometimes problems in the power supply can misconfigure your dryer's sensors, so we're going to reset it to get these sensors back to normal. To do this, the first thing you need to do is disconnect the dryer from the power supply for a few minutes and then reconnect it. Now turn it on and check if the error code has disappeared. It is important that the waiting time is at least 10 to 15 minutes.
2. Check the power supply reaching your Siemens dryer: You need to check that the dryer is receiving the correct power to operate. Consult the manufacturer's manual, and once you have this information, thoroughly check the electrical supply in your home and the socket where you have the dryer connected. Remember that each socket has an amperage limit, so we recommend keeping only one socket for your washer and dryer, using only one appliance at a time and disconnecting all other devices or appliances sharing the same connection. If you do not have the manufacturer's manual at hand, you can try connecting the dryer to another electrical outlet in your home and check if it works well there and if the fault has disappeared.
3. Check the electrical wiring reaching your Siemens dryer: You need to inspect the condition of the wires connecting the dryer to the electrical network. If you see any broken, loose, burnt, or very damaged wires, you will need to replace or repair them as you see fit. This wiring must be in perfect condition to avoid problems with your dryer. Consult the manufacturer's manual or consult with an electrician to know the measurement and thickness this wiring should have for this type of heavy appliances.
4. Check the internal electrical wiring of your Siemens dryer: Check the dryer inside and make sure that the terminals and connectors connecting the wires to the PCB electronic board are properly tightened and positioned. If you see any loose or incorrectly placed terminals or connectors, you must tighten or place them correctly in their position. You also need to check that they are not sulfated and that they are clean. If you notice sulfate, then you will have to remove it with a specific product for it or with an electronic cleaner and a soft-bristled brush or sandpaper.
5. Check the fuses of your Siemens dryer: You need to check that the fuses protecting the dryer's PCB electronic board are not blown. Remember that fuses are a protection bridge and are what can save the components of your dryer from a voltage spike. It is better for a fuse to be damaged than for a component of your dryer to be damaged. So, if you see any blown fuses, you will need to replace them with a new one of the same amperage.
6. If the problem persists, please review all the steps mentioned above: If you have tried all the above solutions and the problem persists, it is likely that the problem lies in some internal component of the dryer and requires replacement. A second check wouldn't hurt, but if the problem persists then it might be time to call in the professionals. That is why we advise you to briefly review everything we have mentioned so far to make sure you have not skipped any of the previous steps.
7. Contact Siemens technical support to solve the problem: If you have tried everything and cannot repair this fault on your own or if you have doubts about how to do it, it is best to contact the professionals in the field and ensure that the dryer receives proper treatment from an expert. Remember that Siemens technical service is the same as Bosch technical service as they are allies. So, you can call either of them, explain your case, and they can offer you the most appropriate solution for your precious appliance.

In summary, the fault affecting your Siemens dryer, showing you the e09 error code on the screen, is nothing more than an electrical fault that can be both internal and external to your dryer. Among the most common causes that can cause this fault to occur, we have that it could be a failure in the power supply, damaged electrical wiring, loose, incorrectly placed, and/or sulfated terminals, or blown fuses. You have to follow the steps in this guide to find the solution to this problem!

If you have a Bosch or Siemens dryer, you should know that an efficient and stable power supply can extend the life of your appliance. Make sure to keep your dryer in good condition and we recommend installing a voltage regulator or surge protector in the socket. Good luck and happy drying!
