Dyson washing machine error F11
Dyson CR01 error F11 means “no motor action” – the control PCB is not receiving any signal that the motor is turning. This tells you the drum is not rotating, but not why. The cause could be anything from a dislodged drive belt to a wiring fault, worn carbon brushes, or a failed motor. Do not replace parts speculatively.
What Error F11 Means on a Dyson CR01
Dyson’s official explanation for F11 is “no motor action.” In practice this means one of two things: either the motor is genuinely not running, or it is running but the PCB is not receiving the signal that it is (typically from the tacho coil that monitors motor speed).
F11 is a good example of an error code that identifies a symptom rather than a cause. The fact that the drum is not turning is observable without any error code – looking through the door glass during a cycle would reveal the same thing. What the error does not tell you is which component in the drive chain has failed. That requires proper diagnosis.
| Possible cause | How to check | DIY accessible? |
|---|---|---|
| Drive belt off or broken | Spin drum by hand – if unusually free, belt has likely come off. Remove back panel to inspect | Yes – belt replacement is accessible on most machines |
| Worn carbon brushes | Check brushes for wear and charring. See our guide on diagnosing carbon brush faults | Yes – if brushes are accessible and confirmed as the cause |
| Wiring or connection fault | Check wiring connectors at the motor plug and wiring harness for loose or corroded terminals | Yes – visual inspection is straightforward |
| Tacho coil fault | The tacho coil monitors motor speed and reports back to the PCB – a fault here triggers F11 even if the motor is technically running. See our guide on how appliance error codes work | Engineer recommended |
| Motor fault | Only confirmed after belt, brushes, and wiring have been eliminated. Motor testing requires a multimeter | Engineer recommended |
| PCB fault | Control board faults are rarely visible. Only suspect after all other causes have been ruled out | Engineer required |
F11 covers a wide range of possible causes from a simple connection to an expensive motor or PCB. Buying and fitting a new motor because the error says “no motor action” is very likely to be unnecessary and expensive. Work through the accessible checks first – belt, brushes, wiring – before considering costly components.

Frequently Asked Questions
What does error F11 mean on a Dyson CR01 washing machine?
F11 means “no motor action” – the control PCB is not receiving confirmation that the motor is turning. This could mean the motor has genuinely stopped, or that the motor is running but the tacho coil monitoring its speed is not sending a signal. The code identifies the symptom (drum not turning) but not the cause.
What should I check first when I get error F11?
Start with the accessible mechanical causes. Spin the drum by hand – if it turns unusually freely, the drive belt has likely come off or broken. Remove the back panel and inspect the belt. If the belt is intact, check the carbon brushes for wear and charring. Check all wiring connectors at the motor plug for loose or corroded terminals. Only consider motor or PCB replacement after these accessible causes have been eliminated.
Can I fix a Dyson CR01 F11 error myself?
Possibly, depending on the cause. A dislodged drive belt, worn carbon brushes, or a loose wiring connector are all DIY-accessible repairs. A motor fault, tacho coil fault, or PCB fault require more specialist knowledge and equipment to diagnose and repair safely.
