Tumble Dryer Help Forum

Hi guys hope someone can help me out with this bosch t/dry and point me in the right direction. when the dial is turned to choose a program the bottom light (drying) light flashes and it does not start. I have just removed loads of excess fluff from inside the cabinet and just cleared the pump but with no joy. If anyone can help it would be much appreciated.
Thankrob

If anyone is interested it was the front senser that had gone faulty, i also cleared out loads of fluff and it has worked fine..
