Siemens Washing Machine Error f21

What does this issue mean that is affecting your Siemens washing-machine?

Ahhhhh! If you have a Siemens washing-machine and an error code f21 has appeared on the display, it means you have a serious problem with your precious appliance. But today we are here to tell you that this issue might be repairable and that you don’t have much to worry about. We’re going to help you today!

The f21 error code issue in your Siemens washing-machine indicates that there is a problem with the motor of the washing-machine, which can have various causes and solutions. It’s important that you check this issue as soon as possible to prevent further damage to your washing-machine. Today we will explain what this issue might be, what its possible causes are, and how you could solve it in the best possible way.

A failure in the washing-machine motor can prevent the drum from spinning correctly and completing the washing cycles. This failure can be due to several reasons, such as:

• The motor brushes are worn out or broken: The brushes are components that make contact with the motor’s commutator and allow a smooth flow of electric current. If the brushes are in bad condition, either due to wear or a poorly assembled motor, the washing-machine will not receive sufficient energy and will not function properly.
• The motor wiring is damaged or disconnected: The wiring is the set of cables that connect the motor to the washing-machine’s electronic board. If any of these cables are broken, disconnected, or burned, the motor will not work as it normally would.
• There is some foreign object stuck in the motor: As odd as it may seem, it can happen that a small object, like a coin, a clip, or a button, gets into the washing-machine drum and reaches the motor. This can cause the motor to jam and not spin.

Undoubtedly, this type of issue might be somewhat complicated to solve, as you will have to open up your Siemens washing-machine quite a bit to get to the root of the problem. However, we have prepared a list of solutions for you, including some that might be very easy to apply. Let’s go!

How can the f21 issue of the Siemens washing-machine be fixed?

This type of issue can have a solution, so don't get completely discouraged. Follow all the instructions we will leave you below, and you will surely be able to clear the f21 error from your Siemens washing-machine:

1. Restart the washing-machine to reset the sensors: This problem might be solved with a brief restart of the washing-machine. However, this solution is only temporary, as if the problem persists, you will need to thoroughly check the motor of your washing-machine. To restart the appliance and recalibrate the sensors, you need to disconnect the washing-machine from the power outlet for about 15 minutes and then reconnect it. Turn on your Siemens washing-machine and now start a short wash cycle and see if the error has disappeared.
2. Check the motor brushes and replace them if necessary: If the problem is that the motor brushes are worn out or broken, you will need to replace them with new ones. You need to check these brushes thoroughly and verify the condition of the carbon, as this is what usually wears out. To do this, you will have to disassemble the back of the washing-machine and access the motor. Then, you will have to remove the brushes and replace them with compatible ones for your washing-machine model. Reassemble everything, put all the parts back together, and run a wash test to see if the washing-machine works correctly.
3. Check the internal wiring of the motor and repair it if necessary: This issue may occur because the motor wiring is damaged, burned, or disconnected, so you will need to check it and make the necessary repairs. Also check the ends of these cables and their respective connections, as they tend to corrode due to moisture or the washing-machine detergent. To do this, you will have to disassemble the back of the washing-machine and access the motor. Then, you will need to check for any broken, cut, or loose wires and solder or connect them properly. Take the opportunity to perform preventive maintenance with an electronic cleaner on the cable ends, connections, and the electronic board of your Siemens washing-machine. Afterward, reassemble everything and check if the washing-machine works properly by running a wash cycle.
4. Check if there is any foreign object stuck in the motor and remove it if necessary: If the problem is that there is a foreign object stuck in the motor, you will need to carefully remove it to free it. To do this, you will need to disassemble the back of the washing-machine and access the motor. Now, manually turn the motor shaft and see if there is any object blocking it or if it has some type of jam. If there is, you will need to carefully extract it without damaging the motor. Reassemble everything and turn on your washing-machine on a wash cycle to check if it works correctly.
5. Repeat all the previous steps if the problem persists in your Siemens washing-machine: If after performing all the possible solutions above, the issue still appears in your Siemens washing-machine, it may be that the motor problem is more complicated than we thought or that the electronic board is damaged. In that case, you will need to repeat all the previous steps and ensure that everything is in perfect order. If you do not find any anomalies, it may be that the motor or the electronic board are defective and need to be replaced.
6. Contact Siemens technical support to solve the problem: If after repeating all the previous steps, the issue has not disappeared from your Siemens washing-machine, then you will most likely need the help of a professional to find a solution. Remember that Siemens technical support has the knowledge and the right tools for this complicated task, as well as the original spare parts that will give your washing-machine a long life.

In conclusion, we could say that this issue is related to the motor of your washing-machine. It may be that the motor is blocked by a foreign object, or that the brushes are already worn out, or there is a problem with the internal wiring of your washing-machine. To find a solution, you will need to follow the steps we have left for you in this guide and very carefully and meticulously review each one of them.

Remember that to avoid this type of situation in your Siemens washing-machine, it would be ideal to maintain the appliance with good preventive maintenance.
