Indicator light codes for a Bosch Clasixx Condenser Tumble Dryer?

I have a 'new' (14 months) Bosch Clasixx Condenser Tumble Dryer. It starts up as normal with all functions working but after about 5 minutes it stops and two of the program lights flash and a beeper sounds. The two lights that flash are:

Drying ( the top light) and
Anti-Crease/End

This is obviously some type of code to indicate a fault or maintenance function but there is no guide to tell you what it means.

I have cleaned out all the filters/ air coolers etc.

Does anyone have a clue or do I have to call out the Bosch man to tell me its something simple!

Thanks
