Bosch WTV74103G int fault

Hi guys. Hope everyone is well at Whitegoods Towers. I would appreciate your help with an intermittent fault on my old 2004? Bosch Classix Tumble Dryer WTV74103G. FD 8804 200265 I am having increasing episodes whereby the dryer starts for about 30 secs then switches off with either the top drying and bottom anti crease/end lights flashing together and a series of beeps or just the bottom anti crease/end light illuminating also with the 3 ? beeps. After about 4 attempts to start the machine it works.I have defluffed everything that can be defluffed. The exhaust hose and lint filter are clear.I have removed the blanking disc and cleaned out the void at the bottom of the dryer. I have wiped the sensor inside.Rearranged the washing in the drum. Should I call it a day or is it worth having it fixed?
