For all that cannot find the red buttons:
Take the top cover away, look at the back (with your head above the machine) down, there in the middle on a metal plate covering the drive belt, you see a black round switch with a little dark red button and 2 white wires connected to it, this is a thermal resettable fuse. Push this, you almost don't feel it go, but it will sound a little soft click.
To check if there are more fuses that can be reset, check how much wires go from connector P6(a) (on the upper side and little to the left, of the controller board) and follow these to the switches and reset.
Mine had only the one discribed.
check if error is cleared and replace top cover.
Of coarse needless to say that one should CLEAN the filter regulary from preventing this to happen.
