siemens washing machine error e43

What does this fault mean in Siemens washing machines?

Oh no! Do you have a Siemens washing machine with an error on the screen? The fault of error code e43 has appeared and it could indicate a problem with the motor of your precious appliance. But there are solutions! You don't need to worry because today we will guide you through the possible causes and solutions to get your washing machine working perfectly again.

The error code e43 on your Siemens washing machine reveals a fault in the motor, which is responsible for rotating the drum during the wash cycle. This fault can prevent the washing machine from completing its cycle and leave your laundry unwashed. It's important to act promptly when this error appears on your washing machine to avoid further and irreparable damage. Below, we will explain the possible causes and solutions to this problem:

  • Worn-out or broken motor brushes: Brushes are carbon pieces that make contact with the motor's commutator, allowing the flow of electrical current. If they are worn out or broken, the motor won't receive the necessary energy to operate correctly.
  • Damaged motor wiring: The wiring connects the motor to the washing machine's electronic board. If a wire is broken, burned, or disconnected, the motor won't receive the signal to operate correctly.
  • Foreign objects in the motor: It's possible for small objects like coins, clips, or buttons to get into the drum and reach the motor, blocking it and preventing it from rotating.

These are the causes that can lead to this error on your appliance's screen. Fixing this fault in Siemens washing machines may require a certain level of technical knowledge and specific tools, but we will provide you with some steps that do not require extensive technical expertise.

How can I fix the fault E43 error in Siemens washing machine?

This fault doesn't mean you have to get rid of your washing machine at all, as it can be fixed, so now is not the time to feel discouraged. Follow all the instructions we are about to provide below, and we assure you a quick and effective solution:

  1. Reset the washing machine to reset the sensors: A complete reset of the washing machine can help reprogram these sensors and return them to their normal state. To do this, disconnect the washing machine from the power by locating the power cable and unplugging it from the power outlet. Once unplugged, let the washing machine sit for at least 15 minutes. This time allows the internal capacitors to discharge and the memory to reset completely. After the waiting period, reconnect the power cable to the power outlet and ensure the connection is firm and secure. Wait a few seconds for the washing machine to fully power on and select a short wash program, such as the quick wash cycle or rinse and spin cycle. Watch the washing machine closely during the cycle, and if the problem persists, please proceed with the following steps.
  2. Check the motor brushes and replace them if necessary: To check the condition of the motor brushes, you'll need to remove the rear panel of the washing machine and access the motor. Generally, you'll only need to remove a few screws and disengage the locking tabs. The washing machine motor is typically located at the bottom rear of the appliance (a large, round piece with wires connected to it). Locate the motor brushes, which are two carbon pieces in contact with the motor's commutator and are usually found on the sides. If these brushes are worn out, less than 1cm in length, or if you see them broken or showing signs of excessive wear, they need to be replaced with new ones. Make sure to purchase compatible replacements for your Siemens washing machine model. You can find them at stores specializing in appliance parts.
  3. Inspect the internal motor wiring and repair if necessary: To inspect the internal motor wiring, you'll need to remove the rear panel of the washing machine and access the motor. Carefully inspect the internal motor wiring. Look for broken, burned, or disconnected wires. Also, check the wire tips and their connections, as they can corrode due to moisture or laundry detergent. If you find damaged wires, you can attempt to repair them by soldering or replacing the damaged parts of the wire. Take the opportunity to perform preventive maintenance on the internal motor wiring and clean the wire tips and connections with an electronic cleaner specifically designed for such components. Once you've inspected or repaired the internal motor wiring, reassemble the rear panel of the washing machine and reconnect the power.
  4. Check for any foreign objects stuck in the motor and remove if necessary: Carefully rotate the motor shaft manually. If you notice that the motor is stuck or having difficulty turning, there may be a foreign object inside. If you find a foreign object stuck in the motor, carefully remove it using tweezers or a screwdriver. Perform this procedure carefully and ensure not to damage the motor in the process. Once you've removed the foreign object, reassemble the rear panel of the washing machine and reconnect the power. Now, start a short wash cycle to check if the fault has disappeared.
  5. Repeat all the above steps if the problem persists in your Siemens washing machine: It's possible that you overlooked some details during the inspection of the brushes, wiring, or search for foreign objects. Take time to repeat each step meticulously, ensuring to carefully inspect each component. Watch closely for the condition of the brushes, looking for signs of excessive wear or breakage. Thoroughly examine the motor wiring for broken, burned, or disconnected wires. Don't forget to check the wire tips and connections, as they can corrode over time. If you find any foreign object in the motor, carefully remove it to free its rotation. If the problem still persists, then it may likely be a fault in the electronic PCB of your washing machine.
  6. Verify the electronic PCB board of your Siemens washing machine: If you've ruled out motor problems, the electronic PCB board could be causing this fault. The electronic PCB is the "brain" of the washing machine, controlling all its functions. It's important to note that the electronic PCB is a complex and delicate component to analyze. If you don't have the necessary technical knowledge or the right tools to check it, we recommend calling a qualified Siemens technician or a trusted technician to inspect it and diagnose the problem accurately.
  7. Seek Siemens technical support to resolve the issue: If you're not comfortable performing these types of checks on your washing machine or don't have the necessary technical knowledge, don't hesitate to seek professional help from Siemens. It's better to call a qualified technician or a trusted technician before attempting complex repairs on your own, as you could potentially cause further damage to the washing machine, resulting in higher costs and voiding any warranty it may have.

To summarize and conclude for today, you need to know that the e43 error code fault on your Siemens washing machine is related to the motor, whether it's due to blockage, worn brushes, or a wiring issue. To fix it, it's important to follow the steps described in this guide meticulously and with attention to detail. If the problem persists, don't hesitate to seek professional help from Siemens technical support or a qualified technician. Thank you very much for reading us today. Good luck!
