in this case the problem is the main control board to blame for this error.
You could live with the problem as it doesn't really affect the operation other than showing the fluff condition.
Or you can replace the board, which is pretty easy to do and I will help if you choose to do that.
The board requires no soldering, it all plugs in, a lot of plugs so please take a pic or two of the plug placement before removing any wires from that board.
If you need a source for that board I would use this site for price and quality: http://www.ransomspares.co.uk/
I would call them to order this board as they will then ship it out the same day to you;-)
