Hi Peter,
The filter is the only thing on the machine that hasn't been changed. Usually if there is anything with a faulty board, they show physical sigs of failing, but this looks perfect - as new.
I will have to see if I can get a filter board for this machine - can't go back to Warco as we are in a bit of a battle with them over the useless machine they had sold me. Do you - or anyone else reading this thread - have any idea where I could find a board to replace this one?
