Just a message left on answer phone. Think it’s a cooker January 27, 2015 at 7:44 pm #424113 deltraParticipant Re: Miele f90 It is a cooker! Problem is oxygen sensor (found on fixya) January 29, 2015 at 8:52 am #424114 philfishParticipant Re: Miele f90 Done one years ago. Think miele recommend changing all 3 boards (have no idea why) and we all know how expensive miele parts are, so just go for the small oxy sensor board but I would still sit down when they give you the price.
