The Dyson CR01 washing machine error code f11 is one of the many next-to-useless codes that I talk about in my error codes (useful or not?) article.

Samsung washing machines can display an error code 5E. This means the washing machine has a “water drain error”. It’s basically timed out on empty, it’s tried draining out the water for 10 minutes and the water level still hasn’t fallen below a specified level (or at least it thinks it hasn’t)

Some Whirlpool washing machines may display the error FP. This error means “drain failure”. Presumably if your washing machine is displaying this code it will still have some water stuck inside. At the very least the washing machine thinks you have, which is why this error appears.

Indesit washing machines displaying error code F08 or the lights flashing cyclically 8 times usually indicate “Heater relay can’t be activated” or “heater relay stuck”.
