Hi, have a bush over than is 15months old, it will no longer switch on for any of the settings. Took apart and found that the first stage of the cam on the 9 position selector switch has failed. Sprung loaded arrangement is burnt out looks quite poor quality. Have got round the probelm by bypassing stage one of the cam (used male to male spade connector) obviously now to switch on/off I have to use the fused spur.To me i feel the item should have lasted much longer, either fault at POS or poor quality materials. Anyone found this on the bush range or how common is this on ovens in general.
