How can I fix my indesit wie 147 washing machine?

My indesit wie 147 wahing machine has come up with f10 error code when looking up I checked the hose for kinks and the water fill seems ok. I put some unblock drain liqued down over night and put it onto 30 min wash it appeared to be ok but after completing wash the f10 code has appeared again and again it wont turn off without unplugging it and wont do any programme. Any solutions as to what to do?
