How can I fix my Simpson Maxidry 362 tumble dryer?

I have recently moved into a flat with a Simpson Maxidry 362 tumble dryer. When I checked the filture was blocked to the stage it did not work, so I emptyed the filture and it ran great for a couple of week. Then suddenly it started stopping every 5 minutes and needs the reset button pressing every time it stops. Is there any way to fix it? Rather then me pressing the reset button every 5 minutes?
