Dyson Washing Machine Error F11? (here’s why & how to fix)
If you own a Dyson washing machine and it’s displaying the F11 error code the washer will not work. This can be worrying and annoying especially once you find out exactly what the F11 error code indicates.
To find out exactly what the F11 error code means on a Dyson washing machine, and the best way to fix it, keep reading.
What Does The F11 Error Code Mean On A Dyson Washing Machine?
The F11 error code on a Dyson washing machine indicates that there is no motor action. In other words, the motor isn’t working, which will be quite obvious because the drum will not spin.
It means that the motor won’t turn or the PCB (printed circuit board) is receiving signals that the motor isn’t turning. This isn’t really a very helpful error code because it is too generic.
It doesn’t tell you what exactly is wrong with the motor or what’s causing it not to turn, just that the motor isn’t turning.
What Could Cause The F11 Error Code On A Dyson Washer?
There are a number of reasons why the Dyson washing machine could be displaying the F11 error code which include;
| Probable Cause | Solution |
|---|---|
| Electrical Glitch | Disconnect power supply for 10 to 15 minutes |
| Wiring Fault | Contact a technician |
| Failed Bridge Rectifier | Contact a technician |
| Blown Thermal Fuse | Contact a technician |
| Defective Motor | Contact a technician |
| Defective PCB | Contact a technician |
Let’s take a closer look at each of these possibilities;
Electrical Glitch
There’s always the possibility of an electrical or software glitch that causes the PCB to think there’s a problem with the motor. This can often be solved by disconnecting the power supply for 10 to 15 minutes to allow any residue power to dissipate.
Once the power is restored, the error code will have cleared and the washing machine will work normally again. However, if the error code remains or returns shortly afterwards, there is a genuine fault that will need investigating by a technician.
Wiring Fault
It is possible that one of the myriad wires or connectors has become loose or disconnected or even shorted out. This would be enough to prevent the motor from turning or for the PCB to think the motor wasn’t turning.
As there are so many wires and connections that could possibly have failed, we recommend getting a technician to investigate and fix this for you.
The Bridge Rectifier Has Failed
The bridge rectifier or diode bridge as it is also known is designed to convert AC input power (from the mains) into DC output (power that can be used by the appliance). If it fails the motor will not turn.
Investigating and replacing the bridge rectifier is a job best left to a technician.
Blown Thermal Fuse
The thermal fuse is a safety device designed to prevent any of the components overheating or burning out if the temperature of the washing machine gets too high. If the thermal fuse blows the washer will not work and the motor will definitely not turn.
You need to dismantle parts of the washer to access the thermal fuse which is why we recommend contacting a technician to investigate and fix this issue for you.
Defective Motor
It is possible that the motor has developed a fault and has stopped working. If the motor does develop a fault, it won’t turn and nor will the drum of the washer.
This is another job best left to a technician as it involves removing panels from the washing machine and checking the motor, then possibly replacing it.
Washing machine motors can be expensive parts and the technician will be best placed to advise you on whether it’s worth replacing the motor on your existing appliance or buying a new washing machine.
Defective PCB
In some cases, it’s the PCB that has developed a fault. Possibly one of the circuits has shorted or a wire has fused into the board. This could be enough to cause the F11 error code to be displayed.
This is another fault best left to a technician to investigate and replace if necessary. PCBs can also be expensive so you’ll need to work out whether it’s better to replace the PCB or the washing machine.

Frequently Asked Questions
The F11 error code on a Dyson washing machine indicates that the motor isn’t turning.
The F11 error code on a Dyson washing machine could be caused by an electrical glitch, a wiring fault, the bridge rectifier has failed, the thermal fuse has blown, the motor is defective or the PCB (printed circuit board is defective.
You can usually clear an error code from a Dyson washing machine by simply disconnecting the power supply for 10 to 15 minutes. This removes any residue power. Once the washer is reconnected to the power supply, the error code should have disappeared.
