I bought a mixer from a local charity selling page, still boxed and PAT tested, for £3. I used the dough hooks today (homemade focaccia) and the 'hooks' are oriented wrong. The spiral twist, in the hooks, should move the dough downwards (pushing it back into the bowl when kneading). These don't, they pull the dough back up towards the mixer and make a right old mess.
Looking at the mixer the hooks rotate in opposite directions to each other

so the simple fix would be to swap the hooks into the opposite holes, unfortunately there is a fixed washer on one of the hooks so it only fits on one side (one hole is bigger)

a few minutes with the dough hook in the cordless drill and a flat file it's sorted.

The hooks now fit in the opposite holes and dough kneading is restored mess free. I'm presuming it's a manufacturing error, the washer was fitted on the wrong hook.
