Is this the only way they can make sure they break down frequently enough to force you to buy a new device every few years rather than building something that would normally last a generation. Also I guess they might save a couple of pounds in controls. I found a good local appliance repair guy recently (could probably do it myself, but I'm not good at that sort of thing). I intend to try and repair anything from now on rather than buy new.
