What does an "F8" error code mean on a Hotpoint WD860 Washer Drier?

failure 8 look at manual to fix it or i hate to say it unplug it to see if it will reset.

very very easy! Unplug your machine. (WARNING SOME PARTS WILL STILL BE LIVE EVEN WHEN IT IS UNPLUGGED) The pump could be faulty however the pump could be cut out by your floating valve. Tip the washer up to 45 degrees, and lean it against a wall, cuboard etc get someone to hold it so it doesnt slip and fall on you, use a towel so it doesn mark or scratch a cupboard . Get some towels, you will need them to mop up the water, under your machine you will see a black rubber pipe. Pull the pipe off using pliars to loosen the ring clip or a screwdriver if it's a hotpoint or depending on the model, inside the pipe you will find fluff/feathers/money etc blocking it, pull it all out. If you find a small clear 'ping pong' ball, put that back in (as it is a floating non return valve), and now re-fit the pipe. Re-fitting is a little awkward sometimes but take your time and try to push it on as far as you can and tighten the clip or whatever holds it into place. Your washing machine can now be used, wash all the wet towels and try it out with a quickwash and spin.

I didn't find that specific code, but here are some review of this particular washer/dryer.
