i have the above f7 fault code. ive done the button and power to reset the machine but this has not cured the fault. is there anything else i can do or is this the end or call a dyson repair man out?

if you are able to work on your machine in confidence

try removing the rear metal cover and checking the plug that is connected to each motor is fully inserted into its socket
before starting any work make sure to unplug the machine from the electrical supply and turn off the water taps until you are finished
