So there was a burning smell coming from the drier and it would cut out after about 30 mins. I’d cleaned the filter at the front even going so far so force my hand in the filter slot where more fluff had accumulated. (Drier is at least 8 years old). Still burning smell and still cutting out. I couldn’t get hold of a repair guy so did some googling and apparently you should vacuum out the fluff from inside the machine occasionally! Well I couldn’t get the back off to do this but instead disconnected the vent hose from the back and stuck my hand in. The whole inside of the drier was a mass of fluff! I pulled out heaps of it then stuck the vacuum cleaner nozzle and got out as much as I could. No more smell and no more cutting out. But when I think of all that flammable fluff inside the drier...
