the control knob will not turn. Have taken front panel off and there does not appear to be any broken parts. If i press the water control valve the water comes through as normal. When I put panel back on the control Knob is still jammed. Someone may have tried to turn knob the wrong way could this have caused the problem. Any suggestions?

mine did the same. if you take the front cover off you will probably see next to the coged wheel (on the back of the front cover) that a piece of plastic has broken off. I have bought a new front cover but must admit I cannot work out how to now switch it off!
