Error codes are model dependent, so the same brand may have more than one listed.
| Code | Brand | What it means | Confidence |
|---|---|---|---|
| F21 | Bosch | Means a motor-related fault that often stops the machine mid-cycle, prevents spinning, and may lock the door. It is usually caused by worn-out carbon brushes, a motor issue, or a control board glitch. | High |
| F4 | Bosch | Means a motor-related fault, with some models interpreting it as a drainage timeout. It is usually caused by worn carbon brushes, faulty motor wiring, or a malfunctioning control module. | High |
| F42 | Bosch | Means a motor-related fault where the motor is not communicating its speed properly or is running uncontrollably. It is usually caused by a motor tachometer error or worn-out motor carbon brushes. | High |
| F43 | Bosch | Means a motor or spin failure where the drum cannot turn, causing the cycle to fail and often leaving the door locked. It is usually caused by worn carbon brushes, an unbalanced load, or a faulty motor control module. | High |
| F63 | Bosch | Means a critical motor or control board failure, signalling a communication issue between the motor and the main electronics. It is usually caused by worn motor brushes or a faulty motor control module. | High |
| E42 | Siemens | Means there is a motor circuit fault and the motor is not running properly. It is usually caused by worn carbon brushes, a tacho connection failure, or a control module (PCB) issue. | High |
| E43 | Siemens | Means there is a motor circuit fault and the motor cannot turn or spin. It is usually caused by a seized motor, worn carbon brushes, or a drum blockage. | High |
| E44 | Siemens | Means there is a motor error in the motor circuit. It is usually caused by a fault in the motor circuit, the tacho generator, or heavily worn carbon brushes. | High |
| E60 | Siemens | Means the motor cannot turn the drum, particularly as E6009 or E60-09. It is usually caused by drive circuit faults such as a malfunctioning inverter or worn motor carbon brushes. | High |
| F48 | Siemens | Means the motor cannot turn, or the control board loses connection with the motor. It is usually caused by motor failure, electronic control module issues, or damaged wiring. | High |
| F7 | Siemens | Means there is a motor fault or a failure to reach the correct speed during a cycle, which often cuts out the spin, or on some models a door lock issue. It is usually caused by a motor fault, a pump that is not operating, or a door that is not locking. | High |
| F74 | Siemens | Means there is a problem within the motor circuit or a motor control communication failure. It is usually caused by a faulty control board, a faulty control panel, a worn component, or damaged wiring. | High |
| F9 | Siemens | Means the motor cannot reach the required speed or is not communicating with the control module, often because of a severe unbalanced load that prevented the drum from spinning. It is usually caused by a motor fault, a control board fault, or an unbalanced load. | High |

General fitting guidance. The exact steps can vary slightly with the make and model of your washing machine.
Safety: Switch off and unplug at the mains before you start.
This is a pair of high-quality carbon brushes for your washing machine motor. The carbon brushes measure 10mm in width and 43mm in length.
Carbon brushes touch the spinning armature, which helps connect all the electrical components and sends power to the drum or pump. The brushes pull double duty, keeping an eye on how fast the motor goes and making sure everything runs smoothly.
Your carbon brushes need to be replaced when they wear down. Damaged carbon brushes can cause reduced motor performance, intermittent operation, or even motor failure.
These two washing machine carbon brushes fit Bosch, Balay, Constructa, Koenic, Lynx, Neff, Pitsos, Profilo, Siemens, and Viva models.
Before ordering, please verify that this set fits your model using our compatibility checker.
My Bosch VarioPerfect washing machine started showing an E43 error, and wouldn't allow me to finish a washing cycle. After searching online, I found a YouTube video stating it could be the carbon brushes. I always come back to RansonSpares because 1) the prices are good if not better than others, and 2) I've never had a part so far that didn't fit my appliance. The carbon brushes that arrived are cheaper than the originals (different part number) but still work. A bit fiddly to replace but so far, no more errors and the washing machine is working fine.
Used the built in search on the web page and selected this part. paid for next day delivery and it did arrive the next day. Part works as intended but only gave 4 stars for ease of fitting because it has a fiddly spring, once I did the first one and got a bit of a idea of how to do it the second one went on a lot easier. Would defiantly use this company again.
Washing machine on the blink with erratic LED display and error codes indicating door interlock or motor problem or main panel. Didn't want to buy Bosch brushes at twice the price in case I'd mis-diagnosed the fault. Fitted these pattern ones and they did sort the problem so well pleased. Very fiddly to fit but that's due to the Bosch motor design and not these parts. They were spot on for size. Original ones lasted 9 years; if I can get a few years out of these then it's a win, only time will tell. Ransome's service was excellent. I ordered on a Friday and they arrived Wednesday even thought a Bank Holiday Monday was in between. Thanks.
