How serious is the Siemens E21 error?

What does the Siemens E21 error code mean?

The E21 error code appears when the washing machine’s motor is not working correctly. This usually prevents the drum from spinning, which means your laundry won’t be washed or rinsed properly.

Common reasons for this error include:

1. Mechanical issues preventing the drum from turning
2. Worn motor brushes
3. Problems with the wiring
4. Faulty motor or control electronics

How to fix the Siemens E21 error code

Here’s a step-by-step guide you can try before calling a professional:

1. Reset the washing machine
   1. Turn off the machine and unplug it for 5–10 minutes.
   2. Plug it back in and restart. Sometimes the error clears if it was caused by a temporary glitch.
2. Check the drum movement
   1. Open the door and try to turn the drum by hand.
   2. If it’s stuck or difficult to turn, there may be a mechanical obstruction like a stuck item of clothing or debris.
3. Inspect the motor brushes
   1. Motor brushes wear out over time and can stop the motor from running.
   2. If you’re comfortable, remove the back panel and check for worn brushes. Replace them if needed.
4. Check wiring connections
   1. Loose or damaged wires can prevent the motor from receiving power.
   2. Inspect visible wiring for damage or disconnections. Only attempt this if you feel confident; otherwise, call a professional.
5. Replace worn or faulty components

💡Top Tip: The E21 error can sometimes be model-specific, so check your washing machine’s manual for guidance. If you’re unsure or the problem persists, it’s safer to contact Siemens customer service or a qualified technician.
