Dyson washing machine diagnostic code?

Dyson CR02. Had a few different door problems, but the machine seems to have a mind of its own and generally resets itself while we are asleep at night! The message first said to close the outer door. When we tried to close it, something was blocking it and stopping it from closing shut.
We tried the 4 step procedure (temp button, power on, etc) to try and reset the controls and maybe release the door mechanism but then the error code: 404F4F5F6V205S appeared.
We still cannot close the outer door. Any help to reset door mechanism?
